Alpha angle values predict the severity of hip chondral damage in patients with cam-type femoroacetabular impingement syndrome: a systematic review and meta-analysis. Arthroscopy 2024:S0749-8063(24)00634-0. [PMID: 39303967 DOI: 10.1016/j.arthro.2024.08.032] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/20/2024] [Revised: 08/19/2024] [Accepted: 08/20/2024] [Indexed: 09/22/2024]
Abstract
PURPOSE To assess the role of alpha angle (AA) in predicting the severity of hip chondral damage in patients with cam-type femoroacetabular impingement (FAI) syndrome. METHODS Following PRISMA guidelines, a systematic review was performed to summarize and critically appraise studies analyzing the prognostic capability of AA values in predicting the severity of intraoperatively evaluated hip chondral damage in patients with cam-type FAI syndrome. The risk of bias was assessed through the QUIPS tool. Meta-analyses based on groups and individual data from studies with a low risk of bias were conducted. We employed a Cumulative Link Mixed Model (CLMM) to analyze the relationship between AA and the ordinal outcome (chondral damage). The model was adjusted for sex, age, and the lateral center-edge angle (LCEA). Interactions between sex and AA were also investigated, and probabilities were calculated. RESULTS Twelve studies with 4,564 patients were included in a qualitative review (aged 30 to 39 years, 1,822 women [40%]). Studies with a low risk of bias (n = 4; 2945 patients) indicated that AA values are significantly smaller (MD [95% CI] of 10.5° [6.5° to 15°]) in the low-grade chondral damage group (grades 0/I/II) compared to the high-grade chondral damage group (III/IV). The CLMM with individual patient data from studies with low risk of bias (n = 3; 1460 patients) indicated that for each 1° increase in AA, the odds of being in a higher category of chondral damage increase by a factor of 1.04 (OR = 1.04, p < 0.0001). Men were at significantly higher risk (OR = 2.11, p < 0.0001) than women, but no significant interaction between sex and AA was observed (p=0.054). We estimate the average probability of having high-grade chondral damage to be greater than 33% when AA values surpass 71° for men and 90° for women, and greater than 50% when 89° for men and 108° for women. However, the heterogeneity observed across studies should be considered. CONCLUSION The alpha angle is a significant predictor of hip chondral damage severity in patients with cam-type FAI syndrome, regardless of sex, and independently of age and LCEA. Additionally, men are at a higher risk of chondral damage than women, and this risk increases with aging but decreases with the magnitude of the LCEA. LEVEL OF EVIDENCE Level III, systematic review of Level II and III studies.

Rotational femoral osteotomies and cam resection improve hip function and internal rotation for patients with anterior hip impingement and decreased femoral version. J Hip Preserv Surg 2024; 11:85-91. [PMID: 39070203 PMCID: PMC11272641 DOI: 10.1093/jhps/hnad018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/09/2023] [Revised: 03/07/2023] [Accepted: 05/24/2023] [Indexed: 07/30/2024] Open
Abstract
Femoroacetabular impingement (FAI) patients with reduced femoral version (FV) are poorly understood. The aim of this study is to assess (i) hip pain and range of motion, (ii) subjective satisfaction and (iii) subsequent surgeries of symptomatic patients who underwent rotational femoral osteotomies. A retrospective case series involving 18 patients (23 hips, 2014-2018) with anterior hip pain that underwent rotational femoral osteotomies for treatment of decreased FV was performed. The mean preoperative age was 25 ± 6 years (57% male), and all patients had decreased FV < 10° and minimum 1-year follow-up (mean follow-up 2 ± 1 years). Surgical indication was the positive anterior impingement test, limited internal rotation (IR) in 90° of flexion (mean 10 ± 8°) and IR in extension (mean 24 ± 11°), anterosuperior chondrolabral damage in Magnet resonance (MR) arthrography, CT-based measurement of decreased FV (mean 5 ± 3°, Murphy method) and no osteoarthritis (Tönnis Grade 0). Most patients had intra- and extra-articular subspine FAI (patient-specific 3D impingement simulation). Subtrochanteric rotational femoral osteotomies to increase FV (correction 20 ± 4°) were combined with cam resection (78%) and surgical hip dislocation (91%). (i) The positive anterior impingement test decreased significantly (P < 0.001) from pre- to postoperatively (100% to 9%). IR in 90° of flexion increased significantly (P < 0.001, 10 ± 8° to 31 ± 10°). (ii) Subjective satisfaction increased significantly (P < 0.001) from pre- to postoperatively (33% 77%). The mean Merle d'Aubigné and Postel score increased significantly (P < 0.001) from 14 ± 2 (8-15) points to 17 ± 1 (13-18, P < 0.001) points. Most patients (85%) reported at follow-up that they would undergo surgery again. (iii) At follow-up, all 23 hips were preserved (no conversion to total hip arthroplasty). One hip (4%) underwent revision osteosynthesis. Proximal rotational femoral osteotomies combined with cam resection improve hip pain and IR in most FAI patients with decreased FV at short-term follow-up. Rotational femoral osteotomies to increase FV are safe and effective.

Delayed hip arthroscopy for femoroacetabular impingement syndrome does not increase revision but does increase rates of chronic opiate use. J Orthop 2024; 53:49-54. [PMID: 38456177 PMCID: PMC10915368 DOI: 10.1016/j.jor.2024.02.046] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/20/2024] [Accepted: 02/24/2024] [Indexed: 03/09/2024] Open
Abstract
Introduction In recent years, the utilization of hip arthroscopy to treat femoroacetabular impingement syndrome (FAIS) has increased due to its low complication rates, positive impact on patient-reported outcomes (PROs), and association with faster rehabilitation. Despite this, there are high rates of revision and conversion to total hip arthroplasty (THA) in some of these patients. It is unclear whether time from initial FAIS diagnosis to surgery is a risk factor for poor outcomes. In this study, we examined the relationship between timing of hip arthroscopy for FAIS and rates of 2-year revision hip procedures, 2-year conversion to total hip arthroplasty (THA), post-operative medical complications, and opioid prescriptions. Methods This is a retrospective cohort study utilizing the PearlDiver database. Current Procedural Terminology (CPT) and International Classification of Diseases (ICD) codes were used to identify patients who had surgery for FAIS with minimum 2 years follow-up available. Patients were stratified by 3-month intervals into 5 groups based on time from diagnosis of FAIS to hip arthroscopy. Multivariate logistic regression was performed to determine factors independently associated with continued opiate use and subsequent surgeries. Results A total of 14,677 patients were included in the study. The 2-year rate of revision hip arthroscopy was 4.2%. As time from diagnosis to surgery increased, even in multivariate regression analysis, there was a higher risk of filling an opioid prescription 90 days after surgery (P < 0.001). Regression analysis demonstrated that timing of surgery was not associated with 2-year revision hip arthroscopy or conversion to THA. Age, sex, obesity, and tobacco use were significant predictors of revision hip arthroscopy and conversion to THA (p < 0.001). Conclusion There is no significant difference between timing of surgery for FAIS and odds of revision or conversion to THA. Prolonged opiate use after hip arthroscopy was significantly higher as duration from initial FAIS diagnosis to surgery increased. Age, sex, obesity, and tobacco use are significant predictors for revision, conversion to THA, and continued opiate prescriptions.

Abstract
BACKGROUND Although hip arthroscopy has been shown to have beneficial outcomes, there is a paucity of literature examining predictive factors of 10-year clinical outcomes. PURPOSE (1) To identify predictive factors of 10-year outcomes of hip arthroscopy and (2) to compare these factors with those found in 2-year and 5-year studies. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Data were prospectively collected and retrospectively reviewed on all patients undergoing hip arthroscopy between February 2008 and June 2012. Patients were included if they had a minimum 10-year follow-up on 2 patient-reported outcome measures: Nonarthritic Hip Score (NAHS) and modified Harris Hip Score. Exclusion criteria included previous ipsilateral hip conditions. Using bivariate and multivariate analyses, that authors analyzed the effects of 37 pre- and intraoperative variables on the NAHS, modified Harris Hip Score, and conversion to total hip arthroplasty. RESULTS Of the 883 patients who met the inclusion criteria, 734 (83.1%) had follow-up data. The mean follow-up time was 124.4 months (range, 120.0-153.1 months). Six variables were significant predictors of NAHS in both multivariate and bivariate analyses: revision status, body mass index (BMI), duration of symptoms, preoperative NAHS, age at onset of symptoms, and need for acetabular microfracture. Positive predictors of 10-year survivorship included acute injury and gluteus medius repair, while negative predictors included revision arthroscopy, Tönnis grade, acetabular inclination, iliopsoas fractional lengthening, and notchplasty. CONCLUSION Multiple predictive factors including age, BMI, revision status, and preoperative outcome scores were identified for long-term survivorship and functional outcomes. These may prove useful to clinicians in refining indications and guiding patients on expected outcomes of hip arthroscopy.

Abstract
Many patients who cannot squat well in a neutral toe position can only squat in an excessively out-toeing position. This excessive out-toeing squat is thought to be caused by rotational problems of the lower extremities. In this study, we aimed to identify the cause for the inability to squat by measuring and comparing femoral and tibial torsion between an excessive out-toeing squat patient group and a control group representing the general population. Between 2008 and 2022, a patient group comprising 50 lower extremities with excessive out-toeing squats was established. A control group representing the general population was selected from patients aged 0 to 29 years, who underwent lower-extremity CT angiography between 2012 and 2022, using the Clinical Data Warehouse with exclusion criteria applied. A total of 94 lower extremities were included in the control group. The femoral torsional angle (FTA) and tibial torsional angle (TTA) of both groups were measured and compared using Student t test. Additionally, 30 each of those with the highest and lowest 30 FTA values were selected from the patient and control groups, and the TTA was compared between the high- and low-FTA groups using Student t test. The mean FTA was 0.34° (SD, 11.11°) in the patient group and 10.14° (SD, 11.85°) in the control group, with a mean difference of 9.8° and P < .001. The mean TTA was 27.95° (SD, 7.82°) in the patient group and 32.67 ° (SD, 7.58°) in the control group, with a mean difference of 4.72° (P = .001). The mean TTA was 34.3° (SD, 7.72°) in the high-FTA group and 28.17° (SD, 8.35°) in the low-FTA group, with a mean difference of 6.13° (P = .005). Patients with excessive out-toeing squat showed lower FTA and TTA values than the general population. Furthermore, although a correlation between FTA and TTA was not established through Pearson correlation analysis, a tendency was observed where a decrease in FTA was associated with a decrease in TTA. Based on these results, decreased FTA was demonstrated to be one of the major causes of excessive out-toeing squats.

Abstract
PURPOSE To evaluate a large cross-sectional sample of patients utilizing administrative database records and analyze the effects of income, insurance type, and education level on outcomes after hip arthroscopy, including 2-year revision surgery, conversion to total hip arthroplasty (THA), and 90-day hospitalizations. METHODS Current Procedural Terminology codes were used to query the PearlDiver Mariner database from October 2015 to January 2020 for patients undergoing hip arthroscopy with a minimum 2-year follow-up. Patients were categorized by mean family income in their zip code of residence (MFIR), health insurance type, and educational attainment in their zip code of residence (EAR). Two-year revision arthroscopy, conversion to THA, and 90-day hospital readmissions or emergency department (ED) visits were analyzed along socioeconomic strata. RESULTS Multivariate analysis of 33,326 patients revealed that patients with MFIR between $30,000 and $70,000 had lower odds of 2-year revision arthroscopy (odds ratio [OR], 0.63; P < .001), THA conversion (OR, 0.76; P = .050), and 90-day readmission (OR, 0.53; P = .007) compared to MFIR >$100,000. Compared to patients with commercial insurance, patients with Medicare had lower odds of revision arthroscopy (OR, 0.60; P = .035) and THA conversion (OR, 0.46, P < .001) but greater odds of 90-day readmission (OR, 1.74; P = .007). Patients with Medicaid had higher odds of 90-day ED visits (OR, 1.84; P < .001). Patients with low EAR had higher odds of revision arthroscopy (OR, 1.42; P = .005) and THA conversion (OR, 1.58; P = .002) compared to those with high EAR. CONCLUSIONS Following hip arthroscopy, patients residing in areas with lower mean family income were less likely to undergo reoperations and readmissions. Medicare patients showed lower reoperation but higher readmission odds, while Medicaid patients showed higher odds of ED visits. Additionally, higher educational attainment in the zip code of residence is protective against future reoperation. LEVEL OF EVIDENCE Level III, retrospective case series.

Effects of Preexisting Anxiety and Depression on Postoperative Outcomes in Patients Aged 30 Years and Younger Following Hip Arthroscopy for Femoroacetabular Impingement Syndrome. HSS J 2024; 20:214-221. [PMID: 39281985 PMCID: PMC11393620 DOI: 10.1177/15563316231164614] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/14/2022] [Accepted: 12/16/2022] [Indexed: 09/18/2024]
Abstract
Background: Mental health influences postoperative outcomes in orthopedic procedures. Increasing attention is being paid to this effect. Purpose: We sought to evaluate the effect of diagnosed depression, anxiety, or both on postoperative outcomes in patients who have undergone hip arthroscopy for femoroacetabular impingement syndrome (FAIS). Methods: We conducted a retrospective cohort study of 289 patients aged 30 years or younger who underwent hip arthroscopy for FAIS at a single institution from January 2014 to June 2021. Univariate statistics were used to assess differences between patients diagnosed with depression, anxiety, or both, and those without these diagnoses. Differences included demographics, operative characteristics, and postoperative outcomes: duration of postanesthesia care unit (PACU) stay, PACU pain scores, complications, reoperations, postoperative injections, 90-day emergency department (ED) visits, and patient-reported outcome measures (PROMs). Multivariate analysis was used to evaluate risk factors for postoperative complications, including wound infection, documented reinjury, postoperative intra-articular hip injection, and any reoperation. Results: Patients diagnosed with depression, anxiety, or both were more likely to be older, female, and have a higher comorbidity burden. At the time of surgery, they were more likely to undergo concomitant procedures, including bursectomy and iliotibial band release. Postoperatively, they had longer PACU stays (90.5 vs 75.1 minutes) and higher first PACU pain scores (5.9 vs 4.6), as well as higher rates of postoperative injection (18.1 vs 9.2%), any reoperation (13.9% vs 4.6%), and revision hip arthroscopy (11.1% vs. 3.7%). Diagnoses of depression, anxiety, or both were independently predictive of any reoperation (odds ratio [OR] = 2.841) and revision hip arthroscopy (OR = 3.401). Conclusion: This retrospective cohort study found that, in patients undergoing hip arthroscopy for FAIS, there was an association between a diagnosis of depression, anxiety, or both, and increased comorbidities, higher first PACU pain scores, longer PACU stays, and increased rates of postoperative injection, any reoperation, or revision hip arthroscopy. Targeted interventions may improve outcomes, but further study is warranted.

Abstract
PURPOSE To analyze the effects of surgeon-specific factors, including case volume, career duration, fellowship training, practice type, and region of practice, on rates of 2-year revision surgery, conversion to total hip arthroplasty (THA), and 90-day hospitalizations following hip arthroscopy. METHODS The PearlDiver Mariner Database was used to query patients undergoing hip arthroscopy between 2015 and 2018. Surgeons performing these procedures were identified, and surgeon-specific demographics and variables were collected from publicly available data. Patients were followed for 2 years to assess for reoperations, including revision hip arthroscopy and conversion to THA, as well as 90-day hospitalizations, including emergency department visits and hospital readmissions. International Classification of Diseases, Tenth Revision codes were used to track the laterality of revision hip procedures. Associations between surgeon-specific factors and postoperative outcomes were assessed through univariate and multivariate analyses. RESULTS In total, 20,834 patients underwent hip arthroscopy procedures by 468 surgeons. Multivariate analysis with logistic regression adjusted for patient-related factors (age, sex, obesity, Charlson Comorbidity Index, and smoking status) identified increasing surgeon case volume to be associated with increased risk for 2-year revision hip arthroscopy (P < .001), but not 2-year conversion to THA or 90-day hospitalizations. Nonsports medicine fellowship-trained surgeons were associated with greater risk for 2-year THA conversion (P < .001) and 90-day hospital readmissions (P < .01). Surgeons practicing in an academic setting demonstrated greater risk for 90-day hospital readmissions (P < .001). Surgeons practicing in the West region of the United States were more likely to incur 2-year revision hip arthroscopy procedures compared to surgeons in the South, Midwest or Northeast (P < .001). CONCLUSIONS Increasing surgeon hip arthroscopy case volume is associated with an increased risk for 2-year revision hip arthroscopy but not conversion to THA or 90-day hospitalizations. Further, non-sports medicine fellowship-trained surgeons were associated with higher risk for 2-year THA conversion after hip arthroscopy. LEVEL OF EVIDENCE Level III, retrospective cohort analysis.

[PMID: 38352174 PMCID: PMC10863482 DOI: 10.1177/23259671231217494] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/06/2023] [Accepted: 07/31/2023] [Indexed: 02/16/2024] Open
Abstract
Background The conversion rate of hip arthroscopy (HA) to total hip arthroplasty (THA) has been reported to be as high as 10%. Despite identifying factors that increase the risk of conversion, current studies do not stratify patients by type of arthroscopic procedure. Purpose/Hypothesis To analyze the rate and predictors of conversion to THA within 2 years after HA. It was hypothesized that osteoarthritis (OA) and increased patient age would negatively affect the survivorship of HA. Study Design Cohort study; Evidence level, 3. Methods The IBM MarketScan database was utilized to identify patients who underwent HA and converted to THA within 2 years at inpatient and outpatient facilities between 2013 and 2017. Patients were split into 3 procedure cohorts as follows: (1) femoroacetabular osteoplasty (FAO), which included treatment for femoroacetabular impingement; (2) isolated debridement; and (3) isolated labral repair. Cohort characteristics were compared using standardized differences. Conversion rates between the 3 cohorts were compared using chi-square tests. The relationship between age and conversion was assessed using linear regression. Predictors of conversion were analyzed using multivariable logistic regression. The median time to conversion was estimated using Kaplan-Meier tests. Results A total of 5048 patients were identified, and the rates of conversion to THA were 12.86% for isolated debridement, 8.67% for isolated labral repair, and 6.76% for FAO (standardized difference, 0.138). The isolated labral repair cohort had the shortest median time to conversion (isolated labral repair, 10.88 months; isolated debridement, 10.98 months; and FAO, 11.9 months [P = .034). For patients >50 years, isolated debridement had the highest rate of conversion at 18.8%. The conversion rate increased linearly with age. Factors that increased the odds of conversion to THA were OA, having an isolated debridement procedure, and older patient age (P < .05). Conclusion Older patients and those with preexisting OA of the hip were at a significantly increased risk of failing HA and requiring a total hip replacement within 2 years of the index procedure. Younger patients were at low risk of requiring a conversion procedure no matter which arthroscopic procedure was performed.

EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY & TRAUMATOLOGY : ORTHOPEDIE TRAUMATOLOGIE 2024; 34:1219-1251. [PMID: 37768398 PMCID: PMC10858160 DOI: 10.1007/s00590-023-03691-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/04/2023] [Accepted: 08/13/2023] [Indexed: 09/29/2023]
Abstract
PURPOSE Four joint arthroplasty registries (JARs) levels exist based on the recorded data type. Level I JARs are national registries that record primary data. Hospital or institutional JARs (Level II-IV) document further data (patient-reported outcomes, demographic, radiographic). A worldwide list of Level II-IV JARs must be created to effectively assess and categorize these data. METHODS Our study is a systematic scoping review that followed the PRISMA guidelines and included 648 studies. Based on their publications, the study aimed to map the existing Level II-IV JARs worldwide. The secondary aim was to record their lifetime, publications' number and frequency and recognise differences with national JARs. RESULTS One hundred five Level II-IV JARs were identified. Forty-eight hospital-based, 45 institutional, and 12 regional JARs. Fifty JARs were found in America, 39 in Europe, nine in Asia, six in Oceania and one in Africa. They have published 485 cohorts, 91 case-series, 49 case-control, nine cross-sectional studies, eight registry protocols and six randomized trials. Most cohort studies were retrospective. Twenty-three per cent of papers studied patient-reported outcomes, 21.45% surgical complications, 13.73% postoperative clinical and 5.25% radiographic outcomes, and 11.88% were survival analyses. Forty-four JARs have published only one paper. Level I JARs primarily publish implant revision risk annual reports, while Level IV JARs collect comprehensive data to conduct retrospective cohort studies. CONCLUSIONS This is the first study mapping all Level II-IV JARs worldwide. Most JARs are found in Europe and America, reporting on retrospective cohorts, but only a few report on studies systematically.

Prior hip arthroscopy increases the risk of dislocation, reoperation, and revision after hip arthroplasty: An updated meta-analysis and systematic review. J Orthop Sci 2024; 29:157-164. [PMID: 36669953 DOI: 10.1016/j.jos.2022.12.016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/30/2022] [Revised: 12/13/2022] [Accepted: 12/22/2022] [Indexed: 01/20/2023]
Abstract
BACKGROUND The indications for hip arthroscopy have been increasing, as have been the number of patients undergoing total hip arthroplasty (THA) after hip arthroscopy. Several matched cohort studies have assessed the impact of prior hip arthroscopy on THA, but conflicting results have been observed. The purpose of this study was to evaluate the influence of prior arthroscopy on subsequent THA. METHODS This systematic review and meta-analysis were performed in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) 2020 checklist. PubMed, the Cumulative Index to Nursing and Allied Health Literature (CINAHL), and the Cochrane Library were searched to identify relevant studies. Dichotomous variables were summarized qualitatively as a meta-analysis of pooled odds ratios (ORs) and 95% confidence intervals (CIs), and continuous variables were summarized as standardized mean differences and 95% CIs. P-values <0.05 were considered statistically significant. The risk of bias was evaluated for each study, as was publication bias. RESULTS In patients who underwent hip arthroscopy prior to THA, the ORs for dislocation, reoperation, and revision were 2.02 (P = 0.01), 1.66 (P = 0.01), and 2.15 (P = 0.001), respectively. There were no significant between-group differences in the Harris Hip Score (HHS; P = 0.40), WOMAC (P = 0.069), FJS-12 (P = 0.77), estimated blood loss (P = 0.48), and surgical time (P = 0.16). CONCLUSIONS Prior hip arthroscopy is a risk for postoperative dislocation, reoperation, or revision after conversion THA. However, prior hip arthroscopy has no effect on patient-reported outcomes, or operative factors such as surgical time and blood loss.

Abstract
This study aimed to compare the efficacy and safety of arthroscopy with physiotherapy or joint lavage in patients with femoroacetabular impingement (FAI). A meta-analysis using PubMed, Embase, Scopus, and the Cochrane Collaboration Library databases was performed in September 2022. We included studies focusing on patients with FAI who underwent arthroscopic surgery versus those who underwent physiotherapy or arthroscopic lavage. The outcomes were functional scores (iHOT-33 and HOS ADL) and adverse events. Randomized clinical trials were included in the study. The risk of bias in each study was assessed according to Cochrane guidelines for clinical trials. The data were combined using Review Manager version 5.4. (PROSPERO CRD42022375273). Six RCTs were included, from a pool of 839 patients (407 females). The iHOT-33 and HOS ADL scales showed significant differences at 12 months in favor of the arthroscopy group (MD, 10.65; 95% CI 6.54-4.76) and (MD, 8.09; 95% CI 3.11-13.07). MCID was not achieved through arthroscopy in functional variables. The rates of osteoarthritis (OR, 6.18; 95% CI 1.06-36.00) and numbness (OR, 73.73; 95% CI 10.00-43.92) were significantly higher in the arthroscopy group. Arthroscopic surgery showed statistical superiority over the control group without exceeding the MCID in most studies; however, the results might have been influenced by secondary variables. Finally, arthroscopic surgery results in a high rate of conversion to osteoarthritis.

Abstract
Patient-reported outcome measures (PROMs) provide structured information on the patient's health experience and facilitate shared clinical decision-making. Registries that collect PROMs generate essential information about the clinical course and efficacy of interventions. Whilst PROMs are increasingly being used in adult orthopaedic registries, their use in paediatric orthopaedic registries is not well known. The purpose of this systematic review was to identify the frequency and scope of registries that collect PROMs in paediatric orthopaedic patient groups. In July 2023, six databases were systematically searched to identify studies that collected PROMs using a registry amongst patients aged under 18 years with orthopaedic diagnoses. Of 3190 identified articles, 128 unique registries were identified. Three were exclusively paediatric, 27 were majority paediatric, and the remainder included a minority of paediatric patients. One hundred and twenty-eight registries collected 72 different PROMs, and 58% of these PROMs were not validated for a paediatric population. The largest group of orthopaedic registries collected PROMs on knee ligament injuries (21%). There are few reported dedicated orthopaedic registries collecting PROMs in paediatric populations. The majority of PROMs collected amongst paediatric populations by orthopaedic registries are not validated for patients under the age of 18 years. The use of non-validated PROMs by registries greatly impedes their utility and impact. Dedicated orthopaedic registries collecting paediatric-validated PROMs are needed to increase health knowledge, improve decision-making between patients and healthcare providers, and optimise orthopaedic management.

Abstract
BACKGROUND Femoroacetabular impingement (FAI) is a common cause of hip pain, especially in young patients. When left untreated, it has been demonstrated to be a risk factor for the onset or progression of osteoarthritis (OA) and has been identified as one of the main contributors leading to the need for total hip arthroplasty (THA) at a young age. While the short-term therapeutic potential of hip arthroscopy is widely recognized, little is known regarding its potential mid- to long-term preventive effect on the progression of hip OA. PURPOSE To (1) report clinical outcomes of arthroscopically treated FAI syndrome with a minimum 5-year follow-up and compare the results to a cohort with FAI treated nonsurgically and (2) determine the influence of hip arthroscopy on the onset and progression of hip OA in patients diagnosed with FAI. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Patients who had hip pain and were diagnosed with FAI were included. Exclusion criteria were (1) previous or concomitant hip surgery, (2) <5 years of follow-up, and (3) insufficient radiographs. Patients treated with hip arthroscopy were compared with a cohort of patients with FAI who were treated nonsurgically. Kaplan-Meier estimates of failure (defined as conversion to THA) were performed. Bivariate analysis and Cox regression were used to identify factors associated with inferior clinical and radiographic outcomes. RESULTS A total of 957 patients (650 female, 307 male; 1114 hips) (mean age, 28.03 ± 8.9 years [range, 6.5-41.0 years]) with FAI were included. A total of 132 hips underwent hip arthroscopy and 982 hips were nonoperatively treated. The mean follow-up was 12.5 ± 4.7 years (range, 5.0-23.4 years). At the final follow-up, the rate of OA progression was 26.5% in the operative group and 35.2% in the nonoperative cohort (P < .01). Conversion to THA was performed in 6.8% of the surgical patients and 10.5% of the initially nonsurgical patients (P = .19). Additionally, there was no significant difference in the risk of failure between the operatively and nonoperatively treated patients. Male sex, increased age at initial diagnosis, presence of cam morphology, and increased initial Tönnis grade were risk factors for failure (male sex: hazard ratio [HR], 2.3; P < .01; per year of increased age: HR, 1.1; P < .01; presence of cam: HR, 3.5; P < .01; per Tönnis grade: HR, 4.0; P < .01). CONCLUSION At a mean follow-up of nearly 13 years, 7% of patients of the surgical group experienced progression to THA, compared with 11% of the nonoperative control group. While most of the operative group showed little to no OA at final follow-up, moderate OA (Tönnis grade 2) was present in 12% of the cohort compared with 22% of nonsurgical patients. Increased age at diagnosis, male sex, presence of a cam morphology, and presence of initial arthritic joint changes were found to be risk factors for failure. The results of this study demonstrated evidence for a preventive effect of hip arthroscopy on the development and progression of OA in young patients with FAI at mid- to long-term follow-up.

Abstract
OBJECTIVE Although hip arthroscopy is a widely adopted treatment option for hip-related pain, it is unknown whether preoperative clinical information can be used to assist surgical decision-making to avoid offering surgery to patients with limited potential for a successful outcome. We aimed to develop and validate clinical prediction models to identify patients more likely to have an unsuccessful or successful outcome 1 year post hip arthroscopy based on the patient acceptable symptom state. METHODS Patient records were extracted from the Danish Hip Arthroscopy Registry (DHAR). A priori, 26 common clinical variables from DHAR were selected as prognostic factors, including demographics, radiographic parameters of hip morphology and self-reported measures. We used 1082 hip arthroscopy patients (surgery performed 25 April 2012 to 4 October 2017) to develop the clinical prediction models based on logistic regression analyses. The development models were internally validated using bootstrapping and shrinkage before temporal external validation was performed using 464 hip arthroscopy patients (surgery performed 5 October 2017 to 13 May 2019). RESULTS The prediction model for unsuccessful outcomes showed best and acceptable predictive performance on the external validation dataset for all multiple imputations (Nagelkerke R2 range: 0.25-0.26) and calibration (intercept range: -0.10 to -0.11; slope range: 1.06-1.09), and acceptable discrimination (area under the curve range: 0.76-0.77). The prediction model for successful outcomes did not calibrate well, while also showing poor discrimination. CONCLUSION Common clinical variables including demographics, radiographic parameters of hip morphology and self-reported measures were able to predict the probability of having an unsuccessful outcome 1 year after hip arthroscopy, while the model for successful outcome showed unacceptable accuracy. The externally validated prediction model can be used to support clinical evaluation and shared decision making by informing the orthopaedic surgeon and patient about the risk of an unsuccessful outcome, and thus when surgery may not be appropriate.

The HAR-index: a reliable method for evaluating the risk of total hip arthroplasty conversion after hip arthroscopy for femoroacetabular impingement. Knee Surg Sports Traumatol Arthrosc 2023:10.1007/s00167-023-07368-1. [PMID: 36884127 DOI: 10.1007/s00167-023-07368-1] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/08/2022] [Accepted: 02/24/2023] [Indexed: 03/09/2023]
Abstract
PURPOSE Hip arthroscopy is a growing technique in the treatment of femoroacetabular impingement (FAI), but can sometimes lead to unsatisfactory results such as the early conversion to total hip arthroplasty (THA). The purpose of this study is to describe a new tool for assessing the preoperative risk of THA conversion after hip arthroscopy in patients with FAI. METHODS This study is a retrospective analysis of a prospective cohort of 584 patients with FAI who underwent hip arthroscopy at a single centre with a minimum 2 years follow-up. The preoperative variables of these patients were analysed to calculate the risk of each variable for THA. By selecting variables with an area under the receiver operating characteristic (ROC) curve greater than 0.7, a calculator was created to provide a risk index for each patient. RESULTS Four variables (age, body mass index, Tönnis score and ALAD) were associated with an increased risk of THA conversion. The optimal cut-off points for each variable were determined, and a risk index was created. The Hip-Arthroplasty-Risk Index (HAR-Index) is a 0-4 points scale obtained from four binary scores of 0 or 1 depending on whether the cut-off point for each variable was reached or not. The increased risk of THA for each HAR-Index value was 1.1%, 6.2%, 17.9%, 55.1% and 79.3% respectively. The HAR-Index showed a very good predictive capacity with an area under the ROC curve of 0.89. CONCLUSION The HAR-Index is a simple and practical tool for practitioners to make more informed decisions about performing hip arthroscopy in patients with FAI. With a very good predictive capacity, the HAR-Index can help to reduce the rate of conversion to THA. LEVEL OF EVIDENCE Level III.

Abstract
PURPOSE To provide an updated review of recent literature on postoperative outcomes following hip arthroscopy for femoroacetabular impingement syndrome (FAIS), focusing on larger-population studies with a minimum 2-year follow-up published within the last 5 years. METHODS A literature search of the PubMed, Ovid Medline, Web of Science, and Cochrane databases was performed in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Articles were screened for clinical studies published from 2017 to 2022 with greater than 100 patients and minimum 2-year follow-up. Exclusion criteria included failure to report postoperative patient-reported outcomes (PROs), no preoperative radiographic measurements, and surgery for pathology other than FAIS. Data collection included study characteristics, patient demographics, radiographic findings, intraoperative findings, procedures performed, postoperative PROs, and subsequent surgeries. RESULTS Nine studies met inclusion criteria. Mean or median patient ages ranged from 32.3 to 41 years, with 4 studies reporting on greater than 50% female patients. Mean preoperative lateral center edge angles and alpha angles ranged from 30.2° to 37° and from 56.2° to 71°, respectively. Labral repairs (range 69.7%-100%) were performed more commonly than debridements (range 0%-26.3%). All studies demonstrated improved PROs at most recent follow-up. Seven studies reported mean or median modified Harris Hip Scores, with preoperative and postoperative values that ranged from 53.1 to 80 and from 67.4 to 100, respectively. Revision hip arthroscopies and conversions to hip arthroplasty ranged from 0.8% to 11.6% and from 0% to 34%, respectively. CONCLUSIONS All included studies found improvements in PROs after hip arthroscopy for FAIS at a minimum of 2-year follow-up. Conversion to total hip arthroplasty is most common in older patients at minimum 10-year follow-up. LEVEL OF EVIDENCE Level IV, systematic review of Level I through IV studies.

Abstract
PURPOSE To assess whether preoperative joint space measures would be predictive of survivorship in patients undergoing hip arthroscopy (HA) for femoroacetabular impingement (FAI). METHODS Data on consecutive patients who underwent hip arthroscopy between February 2008 and February 2018 were retrospectively reviewed. To be eligible for final analysis, patients were required to have preoperative radiographs for joint space measurements and data indicating conversion to a total hip arthroplasty (THA), hip resurfacing, or neither; at a minimum of 2 years after primary hip arthroscopy. Survivorship following HA was defined as remaining conversion free and served as the primary outcome. A multivariate logistic regression analysis and receiver operator curve (ROC) were used to evaluate the correlation between joint space measurements and survivorship following HA. RESULTS A total of 1,885 primary arthroscopy cases were included in this study. The multivariate regression analysis found preoperative lateral-to-medial joint space ratio (L/M ratio) to be the strongest predictive factor of survivorship after primary hip arthroscopy (OR = 2.084, CI95% = 1.239-3.503; P = .006). The ROC curve for the model demonstrated acceptable discrimination with an area under the curve (AUC) of 0.792. Patients with an L/M ratio ≥0.75 had a survivorship rate of 91.7% compared to a rate of 75% for patients with an L/M ratio <0.75 (OR: 3.68). CONCLUSIONS This study found that, of the factors evaluated in this study, the most significant factor in predicting survivorship at 2 years after undergoing primary hip arthroscopy was a larger lateral-to-medial joint space ratio. This may suggest an initiation of primary arthritis at the edge-loading area of the lateral acetabulum. LEVEL OF EVIDENCE: III, retrospective comparative observation study.

Femoral Version May Impact Hip Arthroscopy Outcomes in Select Patient Populations: A Systematic Review. Arthroscopy 2023; 39:114-127. [PMID: 35810977 DOI: 10.1016/j.arthro.2022.06.026] [Citation(s) in RCA: 8] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/07/2022] [Revised: 06/14/2022] [Accepted: 06/23/2022] [Indexed: 02/02/2023]
Abstract
PURPOSE To provide further clarity regarding the management of patients with abnormal femoral version in the setting of hip arthroscopy and will discuss the definition of femoral version, the diagnostic and clinical evaluation of abnormal femoral version, and several described measurement techniques. METHODS A systematic review was conducted in literature published before August 2021 that measured femoral version and reported patient-reported outcomes measures or rates of subsequent procedures following hip arthroscopy. Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed and the electronic databases, PubMed, OvidMedLine, Scopus, and Web of Science were searched. Two blinded reviews screened and evaluated data quality using the Newcastle-Ottawa Scale. RESULTS Eighteen studies were included with 11 studies reporting patient outcomes and 7 studies reporting rates of subsequent procedures. The most commonly used definition of femoral version was 5° to 20° of femoral anteversion. Computed tomography scan was the most commonly used imaging modality. The majority of studies (7 of 11) demonstrated that femoral version does not have an impact on patient-reported outcomes measures and is not predictive of clinically meaningful improvement scores. However, in select studies, patients with femoral retroversion were found to experience slightly inferior outcomes following hip arthroscopy for femoroacetabular impingement. While femoral retroversion may be a risk factor for subsequent procedures, 3 of 7 studies refute this claim. Although in patients with borderline hip dysplasia, excessive femoral anteversion led to greater rates of subsequent hip procedures. CONCLUSIONS While the majority of studies show that femoral version does not have an impact on patient-reported outcomes following hip arthroscopy, those with femoral retroversion and with excessive anteversion with coexisting borderline hip dysplasia need to be educated on their increased risk of subsequent operation. Ultimately, this review suggests that clinical improvement can likely be achieved regardless of femoral version. LEVEL OF EVIDENCE IV; systematic review of Level I-IV studies.

Abstract
Hip cartilage defects are most common in the anterosuperior acetabulum and central femoral head, and, while chondrolabral delamination can be treated satisfactorily with repair, articular defects are variably treated, with overall heterogenous outcomes. Hip chondral lesions have consistently predicted arthroplasty following arthroscopy. Microfracture in isolation has waned in attractiveness and use in both the hip and knee, given similar results to debridement alone and the addition of intraoperative time and potential postoperative complications such as subchondral fracture and intralesional osteophyte formation. We recommend debridement for small-to-moderate (<6 cm2) full-thickness chondral defects. However, the poor prognosis for grade III to IV defects highlights the need for novel treatment options. One such approach is "biologically enhanced" microfracture in conjunction with (autologous) platelet-rich plasma, micronized allograft extracellular cartilage matrix, and fibrin glue. This certainly satisfies our biologic mantra of "cells, signal, and scaffold," providing the influx of marrow-based stromal cells, platelet-rich plasma, and matrix-associated growth factors, and fibrin-sealed defect fill.

Abstract
BACKGROUND Symptomatic patients with femoroacetabular impingement (FAI) have limitations in daily activities and sports and report the exacerbation of hip pain in deep flexion. Yet, the exact impingement location in deep flexion and the effect of femoral version (FV) are unclear. PURPOSE To investigate the acetabular and femoral locations of intra- or extra-articular hip impingement in flexion in patients with FAI with and without femoral retroversion. STUDY DESIGN Cross-sectional study; Level of evidence, 3. METHODS An institutional review board-approved retrospective study involving 84 hips (68 participants) was performed. Of these, symptomatic patients (37 hips) with anterior FAI and femoral retroversion (FV <5°) were compared with symptomatic patients (21 hips) with anterior FAI (normal FV) and with a control group (26 asymptomatic hips without FAI and normal FV). All patients were symptomatic, had anterior hip pain, and had positive anterior impingement test findings. Most of the patients had hip/groin pain in maximal flexion or deep flexion or during sports. All 84 hips underwent pelvic computed tomography (CT) to measure FV as well as validated dynamic impingement simulation with patient-specific CT-based 3-dimensional models using the equidistant method. RESULTS In maximal hip flexion, femoral impingement was located anterior-inferior at 4 o'clock (57%) and 5 o'clock (32%) in patients with femoral retroversion and mostly at 5 o'clock in patients without femoral retroversion (69%) and in asymptomatic controls (76%). Acetabular intra-articular impingement was located anterior-superior (2 o'clock) in all 3 groups. In 125° of flexion, patients with femoral retroversion had a significantly (P < .001) higher prevalence of anterior extra-articular subspine impingement (54%) and anterior intra-articular impingement (89%) compared with the control group (29% and 62%, respectively). CONCLUSION Knowing the exact location of hip impingement in deep flexion has implications for surgical treatment, sports, and physical therapy and confirms previous recommendations: Deep flexion (eg, during squats/lunges) should be avoided in patients with FAI and even more in patients with femoral retroversion. Patients with femoral retroversion may benefit and have less pain when avoiding deep flexion. For these patients, the femoral location of the impingement conflict in flexion was different (anterior-inferior) and distal to the cam deformity compared with the location during the anterior impingement test (anterior-superior). This could be important for preoperative planning and bone resection (cam resection or acetabular rim trimming) during hip arthroscopy or open hip preservation surgery to ensure that the region of impingement is appropriately identified before treatment.

A Matched Cohort Study. Orthop J Sports Med 2022; 10:23259671221126508. [PMID: 36199826 PMCID: PMC9528006 DOI: 10.1177/23259671221126508] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/30/2022] [Accepted: 07/27/2022] [Indexed: 12/03/2022] Open
Abstract
Background: Hip arthroscopy (HA) procedures have increased exponentially in recent years. Their effect on outcomes after subsequent total hip arthroplasty (THA) remains unclear. Purpose: To compare rates of complications and opioid claims after elective THA among patients with prior HA versus controls. Study Design: Cohort study; Level of evidence, 3. Methods: Patients who underwent THA were identified in the PearlDiver database. Arthroplasty performed for hip fractures and hip avascular necrosis were excluded. Within this population, patients with HA before arthroplasty (n = 3156) were propensity score matched 1:1 with controls on age, sex, US region, and several comorbidities. Rates of medical complications within 90 days and prosthesis-related complications within 2 years were queried. The number of patients with an opioid claim within 0 to 30 days and subsequent opioid claim(s) during the 90-day global period were obtained to assess rates of prolonged opioid use after arthroplasty. Rates of postoperative complications and opioid claims were compared using logistic regression. Results: Patients with prior HA exhibited significantly lower rates of readmission (5.6% vs 7.3%; odds ratio [OR], 0.72), pulmonary embolism (0.2% vs 0.6%; OR, 0.45), urinary tract infection (3.1% vs 4.0%; OR, 0.75), and blood transfusion (3.6% vs 6.1%; OR, 0.55). The prior HA cohort also exhibited a significantly lower rate of prosthetic joint infection at 1 year postoperatively (0.6% vs 1.3%; OR, 0.50). Rates of dislocation, periprosthetic fracture, mechanical complications, and aseptic revision arthroplasty were statistically comparable between the cohorts within 2 years. The prior HA cohort was significantly less likely to file persistent opioid claims after 30 days postoperatively, including between 31 and 60 days (27.2% vs 33.1%; OR, 0.74) and 61 to 90 days (16.2% vs 20.9%; OR, 0.71). Conclusion: After elective THA, patients with prior HA exhibited significantly lower rates of medical complications and prolonged opioid claims within 90 days and prosthetic joint infection at 1 year. Rates of all other prosthesis-related complications within 2 years were statistically comparable.

Abstract
Purpose To review short-term functional outcomes in patients who underwent hip arthroscopy and to compare their outcomes to those of a demographically similar cohort who underwent total hip arthroplasty (THA). Methods Data were prospectively collected and retrospectively reviewed for patients undergoing hip arthroscopy (SCOPE) between April 2008 and October 2015. SCOPE patients were included if they were ≥35 years, had preoperative and postoperative 2-year follow-up, and had no prior hip condition or ipsilateral hip surgery. SCOPE patients were matched 1:1 to a demographically similar cohort of patients who underwent THA at our institution. Matching criteria included similar age (within 5 years), gender, and body mass index (within 5). SCOPE patients were assessed with modified Harris Hip Score (mHHS), non-arthritic hip score, and visual analogue scale (VAS). THA patients were assessed with mHHS, forgotten joint score, and VAS. Results Sixty-seven patients were included in each cohort. Patients who underwent hip arthroscopy for management of labral tears achieved nearly equivalent mHHS, Health Survey Short Form (SF-12) Mental, SF-12 Physical, Veterans RAND 12 Item Health Survey (VR-12) Mental, VR-12 Physical scores at latest follow-up compared to demographically similar patients who underwent THA. There was no significant difference in mHHS scores (SCOPE = 82.9 ± 16.4 vs THA = 87.3 ± 15, P = .095) between the 2 group groups. In addition, average patient satisfaction on a 10-point scale was 8.1 for the SCOPE cohort and 8.8 for the THA cohort (P = .052). Conclusions Our results show that hip arthroscopy, when performed in patients with the appropriate indications, can lead to comparably excellent outcomes as total hip arthroplasty with significant pain relief at short term follow-up. Level of Evidence Level III, retrospective cohort study.

Abstract
BACKGROUND Increased understanding of the acetabular labrum's role in hip joint biomechanics has led to a greater focus on the conservation and restoration of normal labral anatomic characteristics; however, labral repair is often not possible in the setting of severe intrasubstance damage or deficiency. PURPOSE To compare 5-year postoperative patient-reported outcomes between hips treated with primary complete arthroscopic labral reconstruction and those treated with primary labral repair. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS All hips that underwent primary labral repair or reconstruction by the senior surgeon between January 2015 and December 2015 were included. Hips that had undergone a previous intra-articular procedure were excluded. Visual analog scales and patient-reported outcome (PRO) instruments were completed by patients within 1 week before surgery as a baseline measurement, between 22 and 26 months postoperatively for 2-year outcomes, and between 58 and 62 months for 5-year outcomes. PRO scores collected included the modified Harris Hip Score (mHHS), the 12-Item International Hip Outcome Tool, and the visual analog scale for pain and satisfaction. Pain and satisfaction were assessed using visual analog scales. RESULTS A total of 68 primary labral repairs and 62 primary complete labral reconstructions were included in the final analysis. Patients in the reconstruction cohort were older (38.3 vs 29.9 years; P < .001), had a higher incidence of severe labral tearing (62.90% vs 5.88%; P < .001), required a greater number of concomitant procedures (P < .001), and were more likely to have Beck grade III or IV chondral damage (12.94% vs 1.47%; P < .001). Both groups demonstrated statistically significant increases in outcome scores at minimum 5-year follow-up. Patients who underwent labral reconstruction had a significantly greater increase in mHHS from the preoperative assessment to latest follow-up compared with patients undergoing labral repair (27.43 vs 17.13; P = .04). No statistically significant differences between the 2 cohorts were found in achievement of minimal clinically important difference, Patient Acceptable Symptom State, maximum outcome improvement, and substantial clinical benefit at latest follow-up (P > .05). In total, 2 patients in the repair cohort and 3 patients in the reconstruction cohort required revision arthroscopy (P = .574). Further, 1 patient from each group converted to arthroplasty (P = .947). CONCLUSION The results of this study suggest that primary complete labral reconstruction is a viable surgical option for hips with moderate to severe labral pathology. At minimum 5-year follow-up, labral reconstruction produced similar outcomes to labral repair despite less favorable preoperative patient characteristics in the reconstruction cohort.

Abstract
BACKGROUND The body of literature comparing hip arthroscopy between athletes and nonathletes is relatively scarce. Analyzing these groups can help to shed light on the severity of intra-articular damage and end-stage osteoarthritis that may result from participation in strenuous activities. PURPOSE (1) To compare the intra-articular damage at the time of hip arthroscopy between athletes and nonathletes, and (2) to compare the pre- and postoperative outcomes between the groups. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Patients were considered eligible for analysis if they had received a primary hip arthroscopy between August 2008 and June 2018, were participating in competitive athletics, and had preoperative baseline scores and minimum 2-year follow-up for the following patient-reported outcomes: modified Harris Hip Score, Nonarthritic Hip Score (NAHS), Hip Outcome Score-Sports Specific Subscale, and visual analog scale. Propensity score matching was used to match eligible patients in a 1:1 ratio to patients who were not participating in any sports greater than a recreational level before surgery. RESULTS A total of 234 patients were included. There were no significant differences in the severity of labral tears, ligamentum teres tears, or cartilage damage (P > .05). The procedures performed between cohorts were similar (P > .05). The athlete population had higher preoperative means scores for the modified Harris Hip Score and NAHS (each P < .001). Likewise, the athlete population had higher postoperative means scores for the NAHS, Hip Outcome Score-Sports Specific Subscale, and visual analog scale (P = .031, P = .030, and P = .032, respectively). Additionally, the athlete cohort reported higher minimum 2-year outcomes than the nonathlete cohort for the 12-Item Short Form Health Survey (mental component; P = .003) and Veterans RAND 12-Item Health Survey (mental component, P = .032; physical component, P = .005). CONCLUSION At the time of hip arthroscopy, athletes demonstrate similar intra-articular damage to their nonathlete counterparts. Given their higher preoperative scores, it is possible that athletes better tolerate the damage to the hip joint. Despite their strenuous activities and potentially higher tolerance to pain, athletes should not necessarily be expected to have greater severity of intra-articular pathology.

Abstract
Aims The frequency of severe femoral retroversion is unclear in patients with femoroacetabular impingement (FAI). This study aimed to investigate mean femoral version (FV), the frequency of absolute femoral retroversion, and the combination of decreased FV and acetabular retroversion (AR) in symptomatic patients with FAI subtypes. Methods A retrospective institutional review board-approved observational study was performed with 333 symptomatic patients (384 hips) with hip pain due to FAI evaluated for hip preservation surgery. Overall, 142 patients (165 hips) had cam-type FAI, while 118 patients (137 hips) had mixed-type FAI. The allocation to each subgroup was based on reference values calculated on anteroposterior radiographs. CT/MRI-based measurement of FV (Murphy method) and AV were retrospectively compared among five FAI subgroups. Frequency of decreased FV < 10°, severely decreased FV < 5°, and absolute femoral retroversion (FV < 0°) was analyzed. Results A significantly (p < 0.001) lower mean FV was found in patients with cam-type FAI (15° (SD 10°)), and in patients with mixed-type FAI (17° (SD 11°)) compared to severe over-coverage (20° (SD 12°). Frequency of decreased FV < 10° was significantly (p < 0.001) higher in patients with cam-type FAI (28%, 46 hips) and in patients with over-coverage (29%, 11 hips) compared to severe over-coverage (12%, 5 hips). Absolute femoral retroversion (FV < 0°) was found in 13% (5 hips) of patients with over-coverage, 6% (10 hips) of patients with cam-type FAI, and 5% (7 hips) of patients with mixed-type FAI. The frequency of decreased FV< 10° combined with acetabular retroversion (AV < 10°) was 6% (8 hips) in patients with mixed-type FAI and 5% (20 hips) in all FAI patients. Of patients with over-coverage, 11% (4 hips) had decreased FV < 10° combined with acetabular retroversion (AV < 10°). Conclusion Patients with cam-type FAI had a considerable proportion (28%) of decreased FV < 10° and 6% had absolute femoral retroversion (FV < 0°), even more for patients with pincer-type FAI due to over-coverage (29% and 13%). This could be important for patients evaluated for open hip preservation surgery or hip arthroscopy, and each patient requires careful personalized evaluation.

Abstract
BACKGROUND Master athletes (MAs), or athletes older than 40 years, make up a patient population whose outcomes after primary arthroscopic hip surgery are largely unknown. PURPOSE To report minimum 2-year outcomes of MAs after primary hip arthroscopy and compare their results to a propensity-matched nonathlete (NA) control group. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Data were prospectively collected between February 2008 and April 2019 and retrospectively reviewed for all patients who underwent primary hip arthroscopy. Patients were included if they were older than 40 years and had preoperative data for the modified Harris Hip Score, Nonarthritic Hip Score, Hip Outcome Score-Sports Specific Subscale, and visual analog scale score for pain. MAs reported participating in organized sports competition within 1 year before surgery and were propensity matched to a control group of patients who did not report participating in organized sports competition (NAs). Patient characteristics, radiographic and intraoperative findings, surgical procedures performed, and patient-reported outcome measures (PROMs) were reported and compared between the groups. The rates of achieving the minimal clinically important difference and maximum outcome improvement satisfaction threshold were recorded. RESULTS A total of 366 hips were eligible; 328 (89.6%) had adequate follow-up data. 328 patients met inclusion criteria but 88 were not included due to the restrictions of the propensity score match ratio. Of these, 80 hips (76 patients) were classified as MAs (mean age, 48.9 ± 6.2 years) and were propensity matched 1:2 to an NA control group. Groups were comparable for baseline demographic and radiographic parameters, intraoperative findings, and procedures performed. MAs had significantly better baseline and minimum 2-year PROM scores (P < .05), higher satisfaction (P = .01), and higher rates of achieving clinically meaningful improvement across all the outcome tools used (P < .05). MAs, when compared with NAs, had lower rates of secondary arthroscopy (0% vs 7.5%, respectively; P = .001) and conversion to total hip arthroplasty (12.5% vs 26.9%, respectively; P = .011). CONCLUSION MAs demonstrated favorable outcomes after primary hip arthroscopy. When compared with a propensity score-matched control group of NA patients, MAs demonstrated better preoperative and postoperative PROMs, higher rates of clinically meaningful improvement, and lower rates of secondary arthroscopy and conversion to total hip arthroplasty. Absolute improvements in PROM scores were similar between the groups.

Abstract
PURPOSE To report minimum 2-year patient-reported outcome scores (PROs) and return to sport (RTS) for competitive athletes undergoing primary hip arthroscopy for femoroacetabular impingement syndrome within 1 year of symptom onset and to compare these results with a propensity-matched control group of competitive athletes with symptoms for over 1 year. METHODS Data on professional, collegiate, high-school, and organized amateur athletes who underwent primary hip arthroscopy within 1 year of symptom onset between April 2008 and November 2017 were collected. RTS and minimum 2-year PROs were collected for the modified Harris Hip Score (mHHS), Non-arthritic Hip Score (NAHS), Hip Outcome Score-Sport Specific Subscale (HOS-SSS), International Hip Outcome Tool (iHOT-12), and visual analog pain scale (VAS). Rates of achieving minimal clinically important difference (MCID) were also evaluated. These patients were propensity-matched to a control group of competitive athletes with symptoms for over one year for comparison. RESULTS Fifty competitive athletes (51 hips, 54.9% female) were included in the study group with a mean follow-up of 70.9 ± 29.1 months and age of 23.6 ± 11.3 years. They demonstrated significant improvement from preoperative to latest follow-up for all recorded PROs (P < .001) and RTS at a rate of 72.9%. When outcomes were compared to the control group, the study group demonstrated similar preoperative scores for all PROs but significantly better minimum 2-year postoperative scores for NAHS (93.8 vs 85.1, P = .0001), HOS-SSS (89.1 vs 77.2, P = .001), iHOT-12 (87.7 vs 76.4, P = 0.011), and VAS (1.5 vs 2.4, P = 0.027). Rates of achieving MCID for HOS-SSS and mHHS were comparable between groups. Further, RTS rates were similar between groups (P = .301). CONCLUSION Competitive athletes undergoing primary hip arthroscopy with symptoms for less than 1 year demonstrated superior 2-year PROs compared to a propensity-matched control group with symptoms for over 1 year, but the rates achieving MCID and RTS were similar between groups. LEVEL OF EVIDENCE Level III, retrospective comparative study.

High-Level Athletes Who Did Not Return to Sport for Reasons Unrelated to Their Hip Achieve Successful Midterm Outcomes With a Benchmarking Against High-Level Athletes Who Returned to Sport. Arthroscopy 2022; 38:1879-1887. [PMID: 34863903 DOI: 10.1016/j.arthro.2021.11.040] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/13/2021] [Revised: 11/12/2021] [Accepted: 11/27/2021] [Indexed: 02/02/2023]
Abstract
PURPOSE 1) To report minimum 2- and 5-year outcomes of high-level athletes who did not return to sport (RTS) after hip arthroscopy for reasons unrelated to their hip (T athletes) and 2) to benchmark these findings against a propensity-matched control group of high-level athletes who returned to sport (RTS athletes). METHODS Data were prospectively collected and retrospectively reviewed for professional, collegiate, and high school athletes between April 2008 and October 2015, who underwent primary hip arthroscopy. Athletes were considered eligible if they did not return to sport for reasons unrelated to their hip such as loss of interest, graduation, or a lifestyle transition (T athletes). Inclusion criteria were preoperative and minimum 5-year postoperative patient-reported outcomes (PROs) for the modified Harris Hip Score (mHHS), Non-Arthritic Hip Score (NAHS), Hip Outcome Score-Sports Specific Subscale (HOS-SSS), and the visual analog scale (VAS) for pain. Clinical outcomes were assessed using the minimal clinically important difference (MCID) and maximum outcome improvement satisfaction threshold (MOIST). T athletes were then propensity-matched to a control group of high-level athletes who returned to sport after hip arthroscopy (RTS athletes) for comparison. RESULTS Twenty-seven T hips (25 patients) were included in the analysis with a mean follow-up time of 38.9 ± 16.8 and 72.1 ± 16.8 months for minimum 2- and 5-year outcomes, respectively. They demonstrated significant improvement in all measured PROs. When compared to a propensity-matched control group of RTS athletes, T athletes demonstrated similar improvement in PROs (mHHS, NAHS, and HOS-SSS) and achieved MCID at similar rates for NAHS (T: 77.8% vs RTS: 68.8%; P = .570) and HOS-SSS (T: 70.3% vs RTS: 76.6%, P = .824) compared to RTS athletes; however T athletes demonstrated higher rates of achieving MCID for mHHS (T: 88.9% vs RTS: 72.9% P = .033). CONCLUSION Athletes who did not return to sport for reasons unrelated to their hip demonstrated favorable outcomes at minimum 2- and 5-year follow-up. They had similar PROs and rates of achieving MCID for HOS-SSS compared to a propensity-matched control group of high-level athletes who returned to sport. Return to sport status may not necessarily be correlated to the patient's perception of their own outcome. LEVEL OF EVIDENCE III, retrospective cohort study.

Abstract
BACKGROUND Personalized medicine models to predict outcomes of orthopaedic surgery are scarce. Many have required data that are only available postoperatively, mitigating their usefulness in preoperative decision making. PURPOSE To establish a method for predictive modeling to enable individualized prognostication and shared decision making based on preoperative patient factors using data from a prospective hip preservation registry. STUDY DESIGN Cohort study (Prognosis); Level of evidence, 2. METHODS Preoperative data of 2415 patients undergoing hip arthroscopy for femoroacetabular impingement syndrome between February 2008 and November 2017 were retrospectively analyzed. Two machine-learning analyses were evaluated: Tree-structured survival analysis (TSSA) and Cox proportional hazards modeling for predicting time to event and for computing hazard ratios for survivorship after hip arthroscopy. The Fine-Gray model was similarly used for repeat hip arthroscopy. Variables were selected for inclusion using the minimum Akaike Information Criterion (AIC). The stepwise selection was used for the Cox and Fine-Gray models. A web-based calculator was created based on the final models. RESULTS Prognostic models were successfully created using Cox proportional hazards modeling and Fine-Gray models for survivorship and repeat hip arthroscopy, respectively. The Harrell C-statistics of the Cox model calculators for survivorship after hip arthroscopy and the Fine-Gray model for repeat hip arthroscopy were 0.848 and 0.662, respectively. Using the AIC, 13 preoperative variables were identified as predictors of survivorship, and 6 variables were identified as predictors for repeat hip arthroscopy. In contrast, the TSSA model performed poorly, resulting in a Harrell C-statistic <0.6, rendering it inaccurate and not interpretable. A web-based calculator was created based on these models. CONCLUSION This study successfully created an institution-specific machine learning-based prognostic model for predictive analytics in patients undergoing hip arthroscopy. Prognostic models to predict survivorship and the need for repeat surgeries were both adapted into web-based tools to assist the physician with shared decision making. This prognostic model may be useful at other institutions after performing external validation. Additionally, this study may serve as proof of concept for a methodology for the development of patient-specific prognostic models. This methodology may be used to create other predictive analytics models in different realms of orthopaedic surgery, contributing to the evolution from evidence-based medicine to personalized medicine.

Combined abnormalities of femoral version and acetabular version and McKibbin Index in FAI patients evaluated for hip preservation surgery. J Hip Preserv Surg 2022; 9:67-77. [PMID: 35854804 PMCID: PMC9291377 DOI: 10.1093/jhps/hnac016] [Citation(s) in RCA: 15] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/01/2021] [Revised: 02/20/2022] [Accepted: 03/07/2022] [Indexed: 01/04/2023] Open
Abstract
Frequencies of combined abnormalities of femoral version (FV) and acetabular version (AV) and of abnormalities of the McKibbin index are unknown. To investigate the prevalence of combined abnormalities of FV and AV and of abnormalities of the McKibbin index in symptomatic patients with femoroacetabular impingement (FAI), a retrospective, Institutional Review Board (IRB)-approved study of 333 symptomatic patients (384 hips) that were presented with hip pain and FAI was performed. The computed tomography/magnetic resonance imaging based measurement of central AV, cranial AV and FV was compared among five subgroups with distinguished FAI subgroups and patients that underwent a hip preservation surgery. The allocation to each subgroup was based on AP radiographs. Normal AV and FV were 10–25°. The McKibbin index is the sum of central AV and FV. Of patients that underwent a hip preservation surgery, 73% had a normal McKibbin index (20–50°) but 27% had an abnormal McKibbin index. Of all patients, 72% had a normal McKibbin index, but 28% had abnormal McKibbin index. The prevalence of combined abnormalities of FV and AV varied among subgroups: a higher prevalence of decreased central AV combined with decreased FV of patients with acetabular-retroversion group (12%) and overcoverage (11%) was found compared with mixed-type FAI (5%). Normal AV combined with normal FV was present in 41% of patients with cam-type FAI and in 34% of patients with overcoverage. Patients that underwent a hip preservation surgery had normal mean FV (17 ± 11°), central AV (19 ± 7°), cranial AV (16 ± 10°) and McKibbin index (36 ± 14°). Frequency of combined abnormalities of AV and FV differs between subgroups of FAI patients. Aggravated and compensated McKibbin index was prevalent in FAI patients. This has implications for open hip preservation surgery (surgical hip dislocation or femoral derotation osteotomy) or hip arthroscopy or non-operative treatment.

Abstract
PURPOSE To identify clinical and radiographic factors that predict return to sport in athletes undergoing hip arthroscopy and to determine thresholds for significant predictors. METHODS Data were reviewed on all patients who underwent primary hip arthroscopy between November 2008 and August 2018. Patients were included if they played professional, college, or high school sports within 1 year before surgery and had preoperative, 3-month, 1-year, and 2-year postoperative patient-reported outcome scores for modified Harris Hip Score, Hip Outcome Score-Sport Specific-Subscale, and Nonarthritic Hip Score. Rates of achieving the minimal clinically important difference also were evaluated. Patients were divided into groups based on whether they returned to sport at the same or greater level. Multivariate logistic regression and receiver operator characteristic analysis were used to evaluate the correlation between significant variables and return to sport. RESULTS A total of 136 patients with a mean age of 20.8 ± 7.07 years were included. Among athletes who attempted to return, professional and collegiate athletes returned to sport at any level at a rate of 85.0% (51/60), and high-school athletes returned at a rate of 88.1% (52/59). Competition level, postoperative alpha angle, change in alpha angle, and postoperative patient-reported outcomes were significantly different between groups. Athletes who returned to sport achieved the minimal clinically important difference for Hip Outcome Score-Sport Specific-Subscale at significantly higher rates than athletes who did not return to sport (91.6% vs 71.7%, P = .002, S = 8.97). The multivariate logistic regression model identified postoperative alpha angle as a statistically significant predictor of return to sport (P < .001, S > 9.97 [odds ratio 0.85, 95% confidence interval 0.79-0.91]). The receiver operator characteristic curve for postoperative alpha angle demonstrated acceptable discrimination between patients returning to sport and patients not returning to sport with an area under the curve of 0.71 and a threshold value of 46°. Athletes with a postoperative alpha angle ≤46° returned to sport at significantly higher rates than those with a postoperative alpha angle >46° [(P < .001, S > 9.97 [odds ratio 6.3, 95% confidence interval 2.6-15.2]). CONCLUSIONS Postoperative alpha angle was identified as a predictor of return to sport in athletes. The odds of returning to sport were 6.3 times greater in athletes with postoperative alpha angles ≤46° compared with athletes with angles >46°. LEVEL OF EVIDENCE III, retrospective cohort study.

Dunn View Alpha Angle More Useful Than Femoral Head-Neck Offset to Predict Acetabular Cartilage Damage in Patients With Femoroacetabular Impingement Syndrome Undergoing Hip Arthroscopy. Arthroscopy 2022; 38:1193-1200. [PMID: 34537312 DOI: 10.1016/j.arthro.2021.08.039] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/29/2021] [Revised: 07/06/2021] [Accepted: 08/15/2021] [Indexed: 02/02/2023]
Abstract
PURPOSE To identify radiographic measurements and demographics that are predictive of acetabular cartilage damage in patients with femoroacetabular impingement syndrome (FAIS) undergoing hip arthroscopy. More specifically, to compare the predictive value of alpha angle and femoral head-neck offset, as measured on Dunn view radiographs, in determining the preoperative likelihood and severity of acetabular cartilage damage. METHODS Patients were included if they underwent primary hip arthroscopy for FAIS between February 2008 and June 2020. Exclusion criteria were prior ipsilateral hip conditions, Tönnis grade of osteoarthritis >1, unwilling to participate, missing intraoperative, demographic or radiographic variables of interest, and lateral center-edge angle (LCEA) >40° or ≤25°. Fourteen variables were assessed in a bivariate comparison and analyzed in a multivariate logistic model. The Acetabular Labrum Articular Disruption (ALAD) and Outerbridge (OB) classifications were used to define acetabular cartilage defects. Those without damage or those with mild acetabular cartilage damage belonged to the ALAD/OB ≤2 group and those with severe damage belonged to the ALAD/OB ≥ 3 group. RESULTS A total of 1485 patients were analyzed, including 1038 patients with ALAD/OB ≤2 and 447 patients with ALAD/OB ≥3. There was a greater proportion of males in the ALAD/OB ≥3 group (64.21% vs 25.82%; P <.001). The multivariate logistic regression selected age, sex, anterior center-edge angle (ACEA), and alpha angle. Every additional degree in the alpha angle was associated with a 6% increase in the odds of severe acetabular cartilage damage (odds ratio [OR], 1.06 [95% confidence interval [CI], 0.12-8.11]). The multivariate analysis did not identify femoral head-neck offset as a predictor. The odds of severe acetabular cartilage damage were 3.73 times higher in males than females (OR, 3.73 [95% CI, 0.01-1705.96]). Higher age was found to increase the likelihood of ALAD/OB ≥3 (OR, 1.04 [95% CI, 0.13-7.75]). CONCLUSIONS In a multivariate analysis, factors identified as preoperative predictors of acetabular cartilage damage in patients with FAIS were age, sex, ACEA, and alpha angle. Femoral head-neck offset was not predictive, suggesting that Dunn view alpha angle may take precedence as a predictor of acetabular cartilage damage. LEVEL OF EVIDENCE Level III, cohort study.

Abstract
BACKGROUND The workers' compensation (WC) status has been associated with inferior outcomes in orthopaedic procedures and is usually excluded from clinical outcome studies. Therefore, comparative studies based on WC status are scarce. PURPOSE (1) To determine outcomes of patients with WC claims treated with hip arthroscopy for labral tears at a minimum 5-year follow-up and (2) to compare these findings with a propensity score-matched control group without WC claims. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Patients were propensity score matched to a control group without WC claims. Data were prospectively collected for all patients undergoing hip arthroscopy. Patients were included if they received primary hip arthroscopy for labral tears in the setting of femoroacetabular impingement, had a WC claim, and had preoperative and minimum 5-year follow-up patient-reported outcomes ([PROs]; modified Harris Hip Score [mHHS], Non-Arthritic Hip Score [NAHS], Hip Outcome Score-Sports Specific Subscale [HOS-SSS], and visual analog scale [VAS] for pain). Clinical outcomes were measured using the Patient Acceptable Symptom State (PASS), minimal clinically important difference (MCID), and maximum outcome improvement satisfaction threshold (MOI). RESULTS A total of 111 from 132 (84.1%) eligible WC patients met the inclusion criteria with an average follow-up time of 80.3 ± 37.3 months. WC cases demonstrated significant improvement from preoperatively to a minimum 5-year follow-up for mHHS, NAHS, HOS-SSS, and VAS for pain (P < .05). WC patients returned to work at a 66% rate, with an average clearance time of 4.7 months to light duty and 9.5 months to heavy duty. When compared with the control group, the WC group demonstrated lower pre- and postoperative PROs (P < .05); however, WC cases had a greater magnitude of improvement (ΔmHHS [P = .0012], ΔNAHS [P < .001], and ΔHOS-SSS [P = .012]). Rates of achieving MCID and MOI were similar in both groups (P > .05). The WC group went on to receive a future arthroscopy in 19 cases (17.1%), while 10 cases (4.5%) in the control group required revision arthroscopy (P < .001). Patients in both the WC and the control groups converted to total hip arthroplasty at similar rates (13.3% and 15.4%, respectively; P > .05). CONCLUSION Patients with WC claims treated with hip arthroscopic surgery showed significant improvement and high rates of returning to work at a minimum 5-year follow-up. Although having lower scores in PROs and achieving PASS rates, no differences were found in MCID and MOI rates. Furthermore, WC patients had a greater magnitude of improvement from preoperatively to a minimum 5-year follow-up after hip arthroscopy. Therefore, even though more studies are needed to determine the causes of inconsistent outcomes in the WC population, hip arthroscopy can effectively treat labral tears in the setting of femoroacetabular impingement, regardless of the WC status.

Abstract
BACKGROUND Predictors of outcomes in adolescent athletes undergoing hip arthroscopy have not been established. The purpose of this study was to identify factors correlated with achieving the Patient Acceptable Symptomatic State (PASS) for the Hip Outcome Score-Sports Specific Subscale (HOS-SSS) at a minimum 5-year follow-up in adolescent athletes undergoing primary hip arthroscopy. METHODS Data were reviewed on adolescent (below 18 y old) athletes who underwent primary hip arthroscopy for femoroacetabular impingement syndrome between March 2008 and October 2015. Patients were included if they participated in sport within 1 year before surgery and had preoperative, 2-year, and minimum 5-year postoperative patient-reported outcome (PRO) scores for the modified Harris Hip Score, HOS-SSS, Visual Analog Scale for pain (VAS), and Non-Arthritic Hip Score (NAHS). Patients were divided into 2 groups based on whether they achieved PASS for HOS-SSS. Demographics, intraoperative findings, radiographic variables, surgical treatments, and PRO were compared. Multivariate logistic regression with corresponding odds ratios (ORs) quantified the correlation between variables and achievement of the PASS. RESULTS A total of 123 athletes with a mean age of 16.2±1.1 years were included. These athletes demonstrated significant imrpovement from preoperative to minimum 5-year follow-up for all recorded PROs (P<0.001). The multivariate logistic regression model identified preoperative NAHS (P=0.019, OR: 1.033), 2-year postoperative HOS-SSS (P=0.014, OR: 1.037), and 2-year postoperative VAS (P=0.003, OR: 0.590) as statistically significantly correlated with achieving the PASS. Athletes with a 2-year postoperative VAS pain score ≤2 achieved PASS at a rate of 81.9%, while those with a score >2 achieved PASS at a rate of 24.1% (P<0.001, OR: 14.2, 95% confidence interval: 5.23-38.7). CONCLUSIONS Favorable outcome were achieved at mid-term follow-up in adolescent athletes undergoing primary hip arthroscopy. Preoperative NAHS, 2-year postoperative HOS-SSS, and 2-year postoperative VAS pain scores were correlated with achieving the PASS for HOS-SSS at a minimum 5-year follow-up. Patients with 2-year postoperative VAS ≤2 were significantly more likely to achieve the PASS at 5-year follow-up than those with scores >2. LEVEL OF EVIDENCE Level III-case-control study.

Abstract
BACKGROUND Athletes who compete in flexibility sports (FS) place unique demands on their hip joints because of the supraphysiologic range of motion required. PURPOSE To compare the pathologic features, outcomes, and return-to-sports (RTS) rates of high-level athletes participating in FS who underwent hip arthroscopy for femoroacetabular impingement syndrome (FAIS) and labral tear against a propensity score-matched cohort of high-level athletes participating in non-flexibility sports (NFS). STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Data were prospectively collected and retrospectively reviewed for high-level athletes who underwent primary hip arthroscopy for FAIS from April 2008 to December 2018. Patients who participated in FS such as dancing, gymnastics, martial arts, figure skating, and cheerleading were propensity score matched by body mass index, age at time of surgery, sex, sports competition level, and labral treatment to a cohort of high-level athletes participating in all other sports, such as distance running, soccer, volleyball, and softball. Baseline patient characteristics, intraoperative findings, and surgical procedures were compared. Minimum 2-year patient-reported outcome measures were compared for the modified Harris Hip Score, Nonarthritic Hip Score, Hip Outcome Score-Sport Specific Subscale, and visual analog scale for pain and satisfaction. Rates of secondary surgery and RTS were compared. RESULTS A total of 47 patients (50 hips) who participated in FS were included and propensity score matched to 130 patients (150 hips) who participated in NFS. Follow-up time was 37.5 ± 10.4 months (mean ± SD). Most patients (96.0%) were female with a mean age of 19.5 ± 7.3 years. FS athletes had significantly higher rates of femoral head cartilage lesions (Outerbridge ≥2; 12.0% vs 2.0%; P = .008) and ligamentum teres tears (48% vs 26%; P = .003). FS and NFS athletes demonstrated significant clinical improvements after surgery for all patient-reported outcome measures. Of the patients who attempted, 34 (75.6%) participating in FS were able to RTS while 11 (24.4%) were not because of ongoing hip issues. This was not significantly different than the NFS group (P = .073). CONCLUSION High-level athletes who participated in FS and were treated for FAIS with hip arthroscopy exhibited higher rates of femoral head cartilage lesions and ligamentum teres tears requiring debridement when compared with a benchmark group of athletes who participated in other sports. Despite this, both groups demonstrated similar improvements in outcome scores and comparable rates of RTS at minimum 2-year follow-up.

Abstract
BACKGROUND There is a paucity of literature evaluating the effect of low body mass index (BMI) in female patients undergoing primary hip arthroscopy. PURPOSE (1) To report minimum 2-year patient-reported outcome scores for female patients with low BMI who underwent primary hip arthroscopy for femoroacetabular impingement syndrome and (2) to compare these results with a propensity-matched control group of female patients with normal BMI. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Data were collected on all female patients who had low BMI (<18.5) and underwent primary hip arthroscopy between April 2008 and January 2019. Patients were excluded if they had a previous hip arthroscopy; had workers' compensation; were unwilling to participate in the study; or had Tönnis osteoarthritis grade >1, acetabular dysplasia, or a previous hip condition. Minimum 2-year patient-reported outcomes were collected for the modified Harris Hip Score (mHHS), Non-Arthritic Hip Score, Hip Outcome Score-Sport Specific Subscale (HOS-SSS), visual analog scale for pain, and satisfaction. The percentage of patients achieving the minimal clinically important difference (MCID), Patient Acceptable Symptom State (PASS), and maximum outcome improvement satisfaction threshold (MOIST) was also recorded. These patients were propensity matched in a 1:2 ratio to female patients with normal BMI for comparison. RESULTS A total of 43 patients (49 hips) were included with a mean ± SD follow-up of 26.9 ± 8.3 months, age of 24.1 ± 12.6 years, and BMI of 17.7 ± 0.67. These patients demonstrated significant improvement from presurgery to minimum 2-year follow-up for the mHHS, Non-Arthritic Hip Score, HOS-SSS, and visual analog scale (P < .05). When outcomes were compared with 93 control patients (97 hips), female patients with low BMI demonstrated lower rates of achieving the PASS for the mHHS (61.2% vs 77.3%; P = .041) and HOS-SSS (39.5% vs 57.1%; P = .031). Rates of achieving the MCID and MOIST were similar between the groups (P > .05). Female patients with low BMI also had higher rates of revision when compared with the control group, but this did not reach statistical significance (14.2% vs 7.2%; P = .171). CONCLUSION Female patients with low BMI undergoing primary hip arthroscopy for femoroacetabular impingement syndrome demonstrated significant improvement in patient-reported outcomes at minimum 2-year follow-up. When compared with a propensity-matched control group with normal BMI, these patients demonstrated lower rates of achieving the PASS for the mHHS and HOS-SSS. Low BMI in females undergoing primary hip arthroscopy for FAIS may adversely affect outcomes at short-term follow-up.

Abstract
BACKGROUND The Hip Sports Activity Scale (HSAS) is a hip-specific instrument for assessing the present levels of physical activity among patients with femoroacetabular impingement (FAI) syndrome. When evaluating treatment outcomes in patients with FAI syndrome, it is necessary to use joint-specific instruments and ones that can evaluate the levels of physical activity in these patients, such as the HSAS-Brazil. OBJECTIVE To validate the HSAS-Brazil among a group of physically active patients after arthroscopic treatment of FAI syndrome. DESIGN AND SETTING Cross-sectional research of quantitative and qualitative types using data obtained from July 2018 to October 2019. METHODS A total of 58 patients of both genders diagnosed with FAI syndrome and who had undergone hip arthroscopy participated in this research. To establish reliability and validity, patients first answered the Brazilian versions of the 12-Item Short-Form Health Survey (SF-12), Nonarthritic Hip Score (NAHS), and HSAS; after a 48-hour interval, they answered the HSAS-Brazil again. RESULTS For test-retest reliability, the interclass correlation was 0.908 (P < 0.001). The HSAS-Brazil correlated to the NAHS-Brazil (r = 0.63, P < 0.001), as well as the SF-12 (Physical Health) (r = 0.42, P = 0.001). CONCLUSION The HSAS-Brazil was validated and proved to be a reliable and valid scale to assess sports activity levels in physically active patients with FAI syndrome after arthroscopic treatment.

Abstract
PURPOSE To perform a systematic review and meta-analysis of literature and to evaluate the relationship between abnormal femoral version and the development of hip osteoarthritis (OA). METHODS A systematic review was performed following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, evaluating Level I and II studies. Included studies had to provide granular femoral version (FV) information. The severity of OA was ranked on the Kellgren-Lawrence (KL) scale. Excel version 1808 (Microsoft, Redmond, WA) was used to perform a student t test statistical analyses. RESULTS Our review identified 19 qualifying studies-5 Level I and 14 Level II with 1,756 patients. Patients with FV above normal range (>14°) had greater KL scores than patients with normal range FV (mean ± standard deviation; 3.37 ± 1.44 vs 2.05 ± 1.72, P < .05). Analysis of KL scores in patients with FV >24° (>1 standard deviation) versus patients with FV >14° but <24° also demonstrated a positive correlation between increasing FV and KL (4.00 ± 1.96 vs 2.34 ± 0). This was significant independent of the presence or absence of developmental dysplasia of the hip. Retroverted hips (FV<10°) in the present study showed variable OA results upon analysis. CONCLUSIONS The present review suggests that elevated FV may be a risk factor for more severe hip OA with or without the presence of concurrent dysplasia of the hip. The relative amount of increased anteversion appears positively correlated with severity of OA. Although femoral retroversion may impact hip mechanics, in this review it does not appear to strongly correlate with the development of OA. LEVEL OF EVIDENCE II: systematic review of Level I and II studies.

Orthop J Sports Med 2021; 9:23259671211053012. [PMID: 34805421 PMCID: PMC8600560 DOI: 10.1177/23259671211053012] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/03/2021] [Accepted: 08/04/2021] [Indexed: 11/26/2022] Open
Abstract
Background: Research has identified factors that influence achievement rates of threshold
scores on patient-reported outcome measures (PROMs) after hip arthroscopy.
However, little data exist on whether failure to achieve a threshold score
(minimal clinically important difference [MCID] or substantial clinical
benefit [SCB]) in the short term after hip arthroscopy predicts the risk of
future hip surgery. Purpose/Hypothesis: The purpose of this study was to determine if failure to achieve the MCID or
SCB on PROMs within 1 year of hip arthroscopy can be considered a risk
factor for repeat surgery within 5 years of primary hip arthroscopy. It was
hypothesized that failure to achieve threshold scores would increase the
risk of subsequent hip surgery. Study Design: Case-control study; Level of evidence, 3. Methods: A retrospective review of prospectively collected data was completed. Four
PROMs were collected preoperatively and within 1 year of hip arthroscopy:
modified Harris Hip Score, Hip Outcome Score–Activities of Daily Living, Hip
Outcome Score–Sports, and the 33-Item International Hip Outcome Tool. Results: Two cohorts were formed: (1) a study cohort (n = 88) composed of patients who
underwent repeat hip surgery within 5 years of hip arthroscopy and (2) a
control cohort (n = 288) composed of patients who did not require repeat hip
surgery. The study cohort had significantly (P < .001)
lower scores on all postoperative PROMs, and a significantly
(P < .001) smaller percentage of the study cohort
met the MCID and SCB. Multivariable regression analysis demonstrated that
not achieving the MCID or SCB on each of the PROMs is an independent risk
factor for repeat hip surgery. For every PROM in which a patient failed to
achieve the MCID, the odds of subsequent surgery increased by 1.68 (95% CI,
1.42-1.98; P < .001). For every PROM in which a patient
failed to achieve the SCB, the odds of subsequent surgery increased by 1.63
(95% CI, 1.35-1.97; P < .001). Conclusion: Failure to meet threshold scores on PROMs after hip arthroscopy was an
independent risk factor for subsequent hip surgery. This study establishes a
novel utility of PROMs and confirms the importance of these metrics in the
orthopaedic literature.

Abstract
BACKGROUND Outcomes of revision hip arthroscopy in the athletic population have not been well established. PURPOSE (1) To report clinical outcomes for high-level athletes undergoing revision hip arthroscopy in the setting of femoroacetabular impingement syndrome (FAIS) or labral tears and (2) to compare these outcomes against a propensity-matched group of high-level athletes undergoing primary hip arthroscopy. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Data for professional, college, and high school athletes were prospectively collected and retrospectively reviewed between January 2012 and October 2018. Patients were included if they underwent revision or primary hip arthroscopy and had preoperative and minimum 2-year patient-reported outcome (PRO) scores for modified Harris Hip Score (mHHS), Non-Arthritic Hip Score (NAHS), Hip Outcome Score Sports-Specific Subscale (HOS-SSS), and visual analog scale (VAS) for pain. The findings and outcomes of revision athletes were compared with a propensity-matched control group of high-level athletes undergoing primary hip arthroscopy. RESULTS A total of 32 hips (29 patients) undergoing revision hip arthroscopy and 92 hips (88 patients) undergoing primary hip arthroscopy were included in our final analysis with a median follow-up time of 29.5 months (95% CI, 27.2-32.1 months) and 36.5 months (95% CI, 33.5-37.7 months), respectively. Athletes undergoing revision surgery showed significant improvement in all recorded PRO measurements and achieved patient acceptable symptomatic state (PASS) and minimal clinically important difference (MCID) for mHHS at high rates (80.6% and 83.9%, respectively). When compared with a propensity-matched primary control group, patients undergoing revision surgery demonstrated lower preoperative and postoperative scores for mHHS, NAHS, and HOS-SSS, but the magnitude of improvement in functional scores was similar between groups. Athletes undergoing revision surgery achieved PASS for HOS-SSS at lower rates than the control group (P = .005), and they were less likely to attempt to return to sport compared with the control group (62.5% vs 87.0%; P < .01). CONCLUSION Revision hip arthroscopy is a viable treatment option to improve PROs in high-level athletes at minimum 2-year follow-up. The study group showed significant improvement in functional scores and a high rate of successful outcomes. They experienced similar magnitude of improvement as that of a propensity-matched control group; however, they achieved lower postoperative PRO scores and attempted to return to sport at lower rates.

Abstract
BACKGROUND High-level athletes (HLAs) have been shown to have better short-term outcomes than nonathletes (NAs) after hip arthroscopy. PURPOSE (1) To report midterm outcomes of HLAs after primary hip arthroscopy and (2) to compare their results with a propensity-matched cohort of NA patients. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Data were prospectively collected and retrospectively reviewed between February 2008 and November 2015 for HLAs (professional, college, or high school) who underwent primary hip arthroscopy in the setting of femoroacetabular impingement syndrome (FAIS). HLAs were included if they had preoperative, minimum 2-year, and minimum 5-year follow-up data for the modified Harris Hip Score (mHHS), Non-Arthritic Hip Score (NAHS), and Hip Outcome Score Sports-Specific Subscale (HOS-SSS). Radiographic and intraoperative findings, surgical procedures, patient-reported outcomes (PROs), patient acceptable symptomatic state (PASS), minimal clinically important difference (MCID), and return to sport were reported. The HLA study group was propensity-matched to a control group of NA patients for comparison. RESULTS A total 65 HLA patients (67 hips) were included in the final analysis with mean follow-up time of 74.6 ± 16.7 months. HLAs showed significant improvement in all PROs recorded, achieved high rates of MCID and PASS for mHHS (74.6% and 79.4%, respectively) and HOS-SSS (67.7% and 66.1%, respectively), and returned to sport at high rates (80.4%). When compared with the propensity-matched NA control group, HLAs reported higher baseline but comparable postoperative scores for the mHHS and NAHS. HLA patients achieved MCID and PASS for mHHS at similar rates as NA patients, but the HLA patients achieved PASS for HOS-SSS at higher rates that trended toward statistical significance (66.1% vs 48.4%; P = .07). NA patients underwent revision arthroscopic surgery at similar rates as HLA patients (14.9% vs 9.0%, respectively; P = .424). CONCLUSION Primary hip arthroscopy results in favorable midterm outcomes in HLAs. When compared with a propensity-matched NA control group, HLAs demonstrated a tendency toward higher rates of achieving PASS for HOS-SSS but similar arthroscopic revision rates at minimum 5-year follow-up.

Clin Orthop Relat Res 2021; 479:2256-2264. [PMID: 33929975 PMCID: PMC8445580 DOI: 10.1097/corr.0000000000001778] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/29/2020] [Accepted: 03/24/2021] [Indexed: 01/31/2023]
Abstract
BACKGROUND Arthroscopic treatment of symptomatic femoroacetabular impingement (FAI) has promising short-term to mid-term results. In addition to treating acute pain or impaired function, the goal of hip-preserving surgery is to achieve a lasting improvement of hip function and to prevent the development of osteoarthritis. Long-term results are necessary to evaluate the effectiveness of surgical treatment and to further improve results by identifying factors associated with conversion to THA. QUESTIONS/PURPOSES (1) How do the Merle d'Aubigné-Postel scores change from before surgery to follow-up of at least 10 years in patients undergoing hip arthroscopy for the treatment of FAI? (2) What is the cumulative 10-year survival rate of hips with the endpoints of conversion to THA or a Merle d'Aubigné-Postel score less than 15? (3) Which factors are associated with conversion to THA? METHODS Between 2003 and 2008, we treated 63 patients (65 hips) for symptomatic FAI with hip arthroscopy at our institution. During that period, the indications for using arthroscopy were correction of anterior cam morphology and anterolateral rim trimming with debridement or reattachment of the labrum. We excluded patients who were younger than 16 years and those who had previous trauma or surgery of the hip. Based on that, 60 patients (62 hips) were eligible. A further 17% (10 of 60) of patients were excluded because the treatment was purely symptomatic without treatment of cam- and/or pincer-type morphology. Of the 50 patients (52 hips) included in the study, 2% (1) of patients were lost before the minimum study follow-up of 10 years, leaving 49 patients (51 hips) for analysis. The median (range) follow-up was 11 years (10 to 17). The median age at surgery was 33 years (16 to 63). Ninety percent (45 of 50) of patients were women. Of the 52 hips, 75% (39 of 52) underwent cam resection (femoral offset correction), 8% (4 of 52) underwent acetabular rim trimming, and 17% (9 of 52) had both procedures. Additionally, in 35% (18 of 52) of hips the labrum was debrided, in 31% (16 of 52) it was resected, and in 10% (5 of 52) of hips the labrum was reattached. The primary clinical outcome measurements were conversion to THA and the Merle d'Aubigné-Postel score. Kaplan-Meier survivorship and Cox regression analyses were performed with endpoints being conversion to THA or Merle d'Aubigné-Postel score less than 15 points. RESULTS The clinical result at 10 years of follow-up was good. The median improvement of the Merle d'Aubigné-Postel score was 3 points (interquartile range 2 to 4), to a median score at last follow-up of 17 points (range 10 to 18). The cumulative 10-year survival rate was 92% (95% CI 85% to 99%) with the endpoints of conversion to THA or Merle d'Aubigné-Postel score less than 15. Factors associated with conversion to THA were each year of advancing age at the time of surgery (hazard ratio 1.1 [95% CI 1.0 to 1.3]; p = 0.01) and preoperative Tönnis Grade 1 compared with Tönnis Grade 0 (no sign of arthritis; HR 17 [95% CI 1.8 to 166]; p = 0.01). CONCLUSION In this series, more than 90% of patients retained their native hips and reported good patient-reported outcome scores at least 10 years after arthroscopic treatment of symptomatic FAI. Younger patients fared better in this series, as did hips without signs of osteoarthritis. Future studies with prospective comparisons of treatment groups are needed to determine how best to treat complex impingement morphologies. LEVEL OF EVIDENCE Level IV, therapeutic study.

Abstract
Arthroscopic techniques in the treatment of femoroacetabular impingement have experienced an exponential increase over recent years for both diagnosis and treatment. The main risks with treatment are poor clinical outcomes and the conversion to prosthesis. Better knowledge and understanding of the various risk factors leading to prosthesis will improve patient selection for arthroscopic treatments rendering better results. The published papers that have been selected are related to series of hip arthroscopies with risk factors that lead to total hip arthroplasty (THA), in the PubMed database, without a time limit, number of patients, or follow-up time. We selected over 302 papers, 19 papers that show risk factors for conversion to THA. The main risk factors found were femoral chondropathy grade III/IV (relative risk 58.1-12 times increased), acetabular (20-2.96 times), an articular space <2 mm (39-4.26 times), age (14.6-1.06 times), Tönnis 2 in radiographic studies (7.73-3.1 times), obesity (5.6-2.3 times), and osteoarthritis (4.6-2.4 times). There are several risk factors which in an isolated way, highly increase the risk of THA. Some of them have a clear relationship (chondropathy, reduced joint space, Tönnis 2, and osteoarthritis). Based on the review we observed that the elements that are most associated with a conversion to THA after a hip arthroscopy are a high degree of femoral and acetabular chondropathy, a reduced joint space below 2 mm, older age, Tönnis 2, obesity, and hip osteoarthritis.

Abstract
BACKGROUND Labral reconstruction has shown promise for the treatment of irreparable labral tears in high-level athletes. The literature is scarce regarding outcomes and timing of return to sports (RTS) in these patients. PURPOSE (1) To report minimum 2-year patient-reported outcome (PRO) scores and RTS characteristics for high-level athletes undergoing primary labral reconstruction for irreparable labral tears and (2) to compare clinical results with a matched control group of athletes undergoing labral repair. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Data were prospectively collected and retrospectively reviewed for high school, college, and professional athletes who underwent a primary arthroscopic labral reconstruction between January 2010 and June 2018. Minimum 2-year PROs were compared for the modified Harris Hip Score (mHHS), Nonarthritic Hip Score (NAHS), and Hip Outcome Score-Sport Specific Subscale (HOS-SSS), as well as the visual analog scale (VAS) pain score, patient satisfaction, and RTS. The percentages of patients achieving the Patient Acceptable Symptom State (PASS) and minimal clinically important difference (MCID) for the mHHS (PASS, >74 points; MCID, >8 points) and HOS-SSS (PASS, >75 points; MCID, >6 points) were also recorded. These patients were propensity score matched in a 1:3 ratio to other high-level athletes undergoing labral repair. RESULTS A total of 17 high-level athletes with primary arthroscopic labral reconstruction were included with a median follow-up time of 37.1 months (95% CI, 37.2-60.3 months). They demonstrated significant improvement from preoperatively to the latest follow-up for mHHS, NAHS, HOS-SSS, and VAS for pain (P < .05). Further, patients achieved PASS/MCID for mHHS at high rates (PASS, 84.2%; MCID, 68.4%). Athletes were able to return to sport-specific training at a median of 3.33 months (95% CI, 3.07-4.71 months) and RTS at a median of 6.2 months (95% CI, 5.08-11.98 months). Fourteen (82.4%) of reconstructions and 29 (82.8%) of repairs either returned to sport or decided not to do so for reasons unrelated to the hip. PROs, RTS rate, and PASS/MCID rates were similar between the labral reconstruction group and a control labral repair group (P > .05). CONCLUSION Primary arthroscopic labral reconstruction for irreparable labral tears was associated with significant improvement in PROs and high rates of RTS in high-level athletes. These results were comparable with those of a control group of athletes undergoing labral repair.

Association Between Comorbid Depression and Rates of Postoperative Complications, Readmissions, and Revision Arthroscopic Procedures After Elective Hip Arthroscopy. Orthop J Sports Med 2021; 9:23259671211036493. [PMID: 34514010 PMCID: PMC8427924 DOI: 10.1177/23259671211036493] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/01/2021] [Accepted: 05/13/2021] [Indexed: 11/16/2022] Open
Abstract
Background: Depression and related psychiatric diagnoses are common in patients undergoing hip arthroscopy for femoroacetabular impingement syndrome (FAIS). The effects of depression on postoperative complications, readmissions, and additional ipsilateral hip surgery are not well studied. Hypothesis: Patients with preoperative depression who undergo hip arthroscopy for FAIS would experience higher rates of 90-day postoperative complications and readmissions, with an increased risk of additional ipsilateral hip procedures, as compared with patients without depression. Study Design: Cohort study; Level of evidence, 3. Methods: A retrospective cohort study between 2010 and 2019 was performed using the Mariner/PearlDiver database. Current Procedural Terminology and International Classification of Diseases codes were used to compare patients with and without preexisting depression who underwent hip arthroscopy for FAIS. Patients were matched at a 1:1 ratio based on age, sex, Charlson Comorbidity Index, body mass index, and tobacco use. Patients undergoing shoulder or knee arthroscopy were also identified to compare lifetime preoperative depression prevalence amongst groups. Results: The lifetime preoperative depression prevalence was significantly higher in patients undergoing hip arthroscopy as compared with patients undergoing shoulder or knee arthroscopy (25.4% vs 22.2% vs 19.8%; P < .001). When compared with the patients without depression, patients with preoperative depression had higher rates of 90-day readmissions (2.4% vs 1.5%) and complications, including urinary tract infection (36.2% vs 28.9%), pneumonia (12.9% vs 9.1%), hematoma formation (3.1% vs 1.9%), acute kidney injury (4.0% vs 2.6%), deep venous thrombosis/pulmonary embolism (2.6% vs 1.7%), and superficial infection (4.9% vs 2.8%; P < .01 for all comparisons). Preoperative depression was associated with significantly higher odds of undergoing revision hip arthroscopy within 2 years (6.3% vs 2.4%; P < .001). Conclusion: Patients with preexisting depression experienced higher rates of 90-day postoperative complications and hospital readmissions after elective hip arthroscopy for FAIS and were more likely to undergo revision hip arthroscopy within 2 years of the index procedure.

Abstract
There is a paucity of literature investigating the effect of lumbopelvic mobility on patient-reported outcome scores (PROs) after primary hip arthroscopy. The purpose of this study was (i) to report minimum 1-year PROs in patients with limited lumbopelvic mobility (LM) who underwent primary hip arthroscopy for femoroacetabular impingement syndrome (FAIS) and (ii) to compare clinical results with a propensity-matched control group of patients with normal lumbopelvic mobility (NM). Data were reviewed for surgeries performed between November 2019 and March 2020. Patients were considered eligible if they received a primary hip arthroscopy for FAIS in the setting of LM (seated to standing change in sacral slope ≤ 10°). LM patients were propensity-matched to a control group of patients with normal lumbopelvic motion (seated to standing change in sacral slope > 10°) for comparison. A total of 17 LM and 34 propensity-matched NM patients were included in the study. LM patients showed significant improvement in all outcome measures and achieved the minimum clinically important difference (MCID) and patient acceptable symptomatic state (PASS) at high rates for modified Harris Hip Score (MCID: 94% and PASS: 82%) and International Hip Outcome Tool-12 (iHOT-12; MCID: 94% and iHOT-12: 76%). When LM patients were compared to a propensity-matched control group of NM patients, they demonstrated similar postoperative PROs and rates of achieving MCID/PASS. LM patients who undergo primary hip arthroscopy may expect favorable short-term PROs at minimum 1-year follow-up. These results were comparable to a control group of NM patients.

Abstract
BACKGROUND Return to sports (RTS) rates and patient-reported outcomes (PROs) after hip arthroscopy in athletes with borderline dysplasia (BD) have not been established. PURPOSE (1) To report minimum 2-year PROs and RTS rates in high-level athletes with BD who underwent hip arthroscopy for labral pathology in the setting of microinstability and (2) to compare clinical results with those of a matched control group of athletes with normal acetabular coverage. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Data were reviewed for surgery performed between January 2012 and July 2018. Patients were considered eligible if they received a primary hip arthroscopy in the setting of BD (lateral center-edge angle, 18°-25°) and competed in professional, collegiate, or high school sports. Inclusion criteria included preoperative and minimum 2-year follow-up scores for the modified Harris Hip Score, Non-arthritic Hip Score, Hip Outcome Score-Sport Specific Subscale, and visual analog scale for pain. Athletes with BD were matched to a control group of athletes with normal acetabular coverage (lateral center-edge angle, 25°-40°). RESULTS A total of 65 patients with BD were included in the study with a mean ± standard deviation follow-up of 47.5 ± 20.4 months. Athletes with BD showed significant improvement in all outcome measures recorded, demonstrated high RTS rates (80.7%), and achieved the minimal clinically important difference (MCID) and Patient Acceptable Symptom State (PASS) for the Hip Outcome Score-Sport Specific Subscale at high rates (MCID, 90.8%; PASS, 75.4%). When compared with a propensity-matched control group with normal acetabular coverage, capsular plication was performed more commonly in the BD group (93.8% vs 82.7%; P = .037). PROs and RTS, PASS, and MCID rates were similar between the BD and control groups (P > .05). CONCLUSION High-level athletes with BD who undergo primary hip arthroscopy for labral pathology in the setting of microinstability may expect favorable PROs and RTS rates at minimum 2-year follow-up. These results were comparable with those of a control group of athletes with normal coverage.

Abstract
INTRODUCTION Femoroacetabular impingement (FAI) is a dynamic pathomechanical process of the femoral head-neck junction. Arthroscopic surgery for FAI has increased exponentially in the last decade, and this trend is expected to increase. SOURCE OF DATA Recent published literatures. AREAS OF AGREEMENT FAI promotes quick rehabilitation and low complication rates in the short-term follow-up. AREAS OF CONTROVERSY Despite the growing interest on arthroscopic surgery for FAI, current evidence regarding the medium- and long-term role of arthroscopy are unsatisfactory. GROWING POINTS Systematically summarize current evidences, analyse the quantitative available data and investigate the medium- and long-term outcomes of arthroscopic surgery for FAI. AREAS TIMELY FOR DEVELOPING RESEARCH Arthroscopic surgery achieves very satisfactory outcomes for patients with FAI at a mean follow-up of 4 years.

Abstract
BACKGROUND Femoroacetabular impingement (FAI) is a recognized cause of hip pain and decreased quality of life and has been linked to primary idiopathic hip osteoarthritis (OA). Although the operative indications for FAI have expanded to include older patients, we do not know whether there is an increased risk of conversion to THA after femoroacetabular osteoplasty (FAO) via the mini-open approach for FAI in patients older than 40 years compared with younger patients, after controlling for other confounding variables. QUESTIONS/PURPOSES (1) After matching for gender, BMI, preoperative symptomatic period, surgeon experience, Tönnis grade, and degree of chondral lesion, are patients older than 40 years who undergo FAO for FAI more likely to be revised to THA at a minimum of 2 years' follow-up than are patients younger than 40? (2) Is there a difference in delta (postoperative minus preoperative) improvement in functional outcome scores in those patients who did not go on to THA between patients older than and younger than 40 years? METHODS Between 2003 and 2017, one surgeon performed 281 FAOs via the mini-open approach in patients older than 40 years and 544 of the same procedure in patients younger than 40 years. During that period, the general indications for FAO were the same in both age groups: (1) history and physical exam consistent with FAI, (2) radiographic evidence of focal impingement (cam, pincer, or both), (3) evidence of labral or chondrolabral tears, and (4) minimal to no arthritic changes (all four criteria required). In general, age was not used as a contraindication for surgery. A total of 86% (241 of 281) of patients older than 40 and 91% (494 of 544) of those younger than 40 were available for minimum of 2 years' follow-up, had complete datasets (radiographs as well as preoperative and most recent patient-reported outcomes scores) at a minimum of 2 years after surgery, and were considered eligible for the match. Propensity score matching was used to match for BMI, gender, preoperative symptomatic period, surgeon experience, Tönnis grade, and degree of intraoperative chondral lesion. We matched at a 1:2 ratio 130 patients older than age 40 with 260 patients younger than age 40. The mean ± SD follow-up duration for both groups was 5 ± 2 years. The mean age of the cohort of interest was 47 ± 5 years compared with 28 ± 7 years in the control. Fifty-four percent (70 of 130) of patients older than 40 years were women and 46% (60 of 130) were men; for those younger than 40, 51% (133 of 260) of participants were women and 49% (127 of 260) were men. Tönnis grade distribution for patients older than 40 was as follows: 46% (60 of 130) had Grade 0, 42% (55 of 130) had Grade 1, and 12% (15 of 130) had Grade 2. In comparison, Tönnis grade for patients younger than 40 was as follows: 52% (136 of 260) had Grade 0, 38% (100 of 260) had Grade 1, and 9% (24 of 260) had Grade 2 (p = 0.49). Chondral lesion degree was determined intraoperatively as none, a partial-thickness tear, or a full-thickness tear. Tönnis grade was determined based on preoperative plain AP hip radiographs. We then compared the percentage of patients who converted to THA during the surveillance period (our primary study outcome). We also compared the difference in delta (preoperative minus postoperative) improvement in functional outcome scores using the modified Harris Hip Score (mHHS) between the groups, excluding those who had already been converted to THA. RESULTS In patients older than 40 years, 16% (21 of 130) converted to THA at a mean time to conversion of 2 ± 1 years compared with 7% (17 of 260) at a mean time of 2 ± 2 years in patients younger than 40 years (p = 0.01). At a mean of 5 ± 2 years after FAO, among those patients who had not undergone conversion to THA, the mean delta mHHS score for patients older than 40 was 11 ± 17, compared with 20 ± 26 for patients younger than 40 (p = 0.04). CONCLUSION Since approximately 1 in 6 patients older than 40 years in this series who underwent FAO for FAI opted for early conversion to THA at a mean time of 2 years after the osteoplasty procedure, and the remaining patients who did not undergo THA reported lower improvement in functional outcomes, we recommend surgeons avoid this procedure in patients in this age group until or unless we can better refine our indications. This is especially true because loss to follow-up causes us to believe that, if anything, our estimates of the risk of conversion to THA are conservative. LEVEL OF EVIDENCE Level III, therapeutic study.
