Abstract
BACKGROUND Hip arthroscopy has demonstrated effectiveness as a treatment for femoroacetabular impingement (FAI) in adult patients, with promising long-term outcomes. However, there is a paucity of literature regarding the adolescent population. The purposes of our study were to report on survivorship and patient-reported outcomes (PROs) at a minimum 10-year follow-up in adolescent patients who underwent hip arthroscopy for FAI and labral tears and to compare the survivorship and outcomes of this population with those of a nested, propensity-matched adult control group. METHODS Data regarding adolescent patients who underwent primary hip arthroscopy between February 2008 and January 2012 were reviewed. Patients with a minimum 10-year follow-up for the modified Harris hip score (mHHS), Non-Arthritic Hip Score (NAHS), Hip Outcome Score Sport-Specific Subscale (HOS-SSS), International Hip Outcome Tool-12 (iHOT-12), and visual analog scale (VAS) for pain were eligible. The exclusion criteria were previous ipsilateral hip conditions or surgical procedures, a Tönnis grade of >1, or dysplasia. In the subanalysis, adolescent patients were matched to young adult patients with use of a 1:1 ratio on the basis of sex, body mass index, Tönnis grade, lateral center-edge angle (LCEA), labral treatment, capsular treatment, and additional procedures performed during the surgery. RESULTS A total of 74 patients (61 female and 13 male; 74 hips) with a mean (and standard deviation) age of 16.7 ± 1.4 years and a minimum follow-up of 10 years were included. The latest follow-up occurred at a mean of 125.4 ± 5.3 months (range, 120.0 to 144.1 months). Significant improvement in all PROs from baseline and 100% survivorship were demonstrated at the 10-year follow-up. In the subanalysis, 58 adolescent hips were propensity-matched to 58 young adult hips. The adolescent group had higher postoperative scores for the HOS-SSS (p = 0.021), NAHS (p = 0.021), and iHOT-12 (p = 0.042) than the young adult group. Patient satisfaction at the latest follow-up was also significantly higher in the adolescent group (p = 0.00061). The rate of survivorship free from conversion to THA was similar between the adolescent and control groups (100% versus 96.6%; p = 0.200). CONCLUSIONS Adolescents undergoing hip arthroscopy for the treatment of FAI and labral tears demonstrated excellent outcomes and a high rate of survivorship. These outcomes were superior to those seen in a matched adult group. The results of this study indicate that hip arthroscopy in adolescents is a safe procedure that leads to improvement in outcomes at long-term follow-up. LEVEL OF EVIDENCE Therapeutic Level IV .

Time-Driven Activity-Based Costing Analysis Identifies Use of Consumables and Operating Room Time as Factors Associated With Increased Cost of Outpatient Primary Hip Arthroscopic Labral Repair. Arthroscopy 2024; 40:1517-1526. [PMID: 37977413 DOI: 10.1016/j.arthro.2023.10.050] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/10/2023] [Revised: 10/02/2023] [Accepted: 10/20/2023] [Indexed: 11/19/2023]
Abstract
PURPOSE To use time-driven, activity-based costing (TDABC) methodology to investigate drivers of cost variation and to elucidate preoperative and intraoperative factors associated with increased cost of outpatient arthroscopic hip labral repair. METHODS A retrospective analysis of data from January 2020 to October 2021 was performed. Patients undergoing primary hip arthroscopy for labral repair in the outpatient setting were included. Indexed TDABC data from Avant-garde Health's analytics platform were used to represent cost-of-care breakdowns. Patients in the top decile of cost were defined as high cost, and cost category variance was determined as a percent increase between high and low cost. Analyses tested for associations between preoperative and perioperative factors with total cost. Surgical procedures performed concomitantly to labral repair were included in subanalyses. RESULTS Data from 151 patients were analyzed. Consumables made up 61% of total outpatient cost with surgical personnel costs (30%) being the second largest category. The average total cost was 19% higher for patients in the top decile of cost compared to the remainder of the cohort. Factors contributing to this difference were implants (36% higher), surgical personnel (20% higher), and operating room (OR) consumables (15% higher). Multivariate linear regression modeling indicated that OR time (Standardized β = 0.504; P < .001) and anchor quantity (standardized β = 0.443; P < .001) were significant predictors of increased cost. Femoroplasty (Unstandardized β = 15.274; P = .010), chondroplasty (Unstandardized β = 8.860; P = .009), excision of os acetabuli (unstandardized β = 13.619; P = .041), and trochanteric bursectomy (Unstandardized β = 21.176; P = .009) were also all independently associated with increasing operating time. CONCLUSIONS TDABC analysis showed that OR consumables and implants were the largest drivers of cost for the procedure. OR time was also shown to be a significant predictor of increased costs.

Abstract
Aims The purpose of this study was to evaluate the mid-term outcomes of autologous matrix-induced chondrogenesis (AMIC) for the treatment of larger cartilage lesions and deformity correction in hips suffering from symptomatic femoroacetabular impingement (FAI). Methods This single-centre study focused on a cohort of 24 patients with cam- or pincer-type FAI, full-thickness femoral or acetabular chondral lesions, or osteochondral lesions ≥ 2 cm2, who underwent surgical hip dislocation for FAI correction in combination with AMIC between March 2009 and February 2016. Baseline data were retrospectively obtained from patient files. Mid-term outcomes were prospectively collected at a follow-up in 2020: cartilage repair tissue quality was evaluated by MRI using the Magnetic Resonance Observation of Cartilage Repair Tissue (MOCART) score. Patient-reported outcome measures (PROMs) included the Oxford Hip Score (OHS) and Core Outcome Measure Index (COMI). Clinical examination included range of motion, impingement tests, and pain. Results A total of 12 hips from 11 patients were included (ten males, one female, mean age 26.8 years (SD 5.0), mean follow-up 6.2 years (SD 5.2 months)). The mean postoperative MOCART score was 66.3 (SD 16.3). None of the patients required conversion to total hip arthroplasty. Two patients had anterior impingement. External hip rotation was moderately limited in four patients. There was a correlation between MOCART and follow-up time (rs = -0.61; p = 0.035), but not with initial cartilage damage, age, BMI, or imaging time delay before surgery. PROMs improved significantly: OHS from 37.4 to 42.7 (p = 0.014) and COMI from 4.1 to 1.6 (p = 0.025). There was no correlation between MOCART and PROMs. Conclusion Based on the reported mid-term results, we consider AMIC as an encouraging treatment option for large cartilage lesions of the hip. Nonetheless, the clinical evidence of AMIC in FAI patients remains to be determined, ideally in the context of randomized controlled trials.

Adhesions After Hip Arthroscopy Are Associated With Revision But Show Poorly Defined Criteria for Diagnosis and Operative Management: A Systematic Review. Arthroscopy 2024:S0749-8063(24)00303-7. [PMID: 38697325 DOI: 10.1016/j.arthro.2024.04.008] [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: 01/02/2024] [Revised: 04/01/2024] [Accepted: 04/09/2024] [Indexed: 05/04/2024]
Abstract
PURPOSE To evaluate the current body of evidence surrounding the diagnosis, management, and clinical outcomes of adhesions that developed after hip arthroscopy (HA). METHODS A systematic search of the MEDLINE, Embase, Web of Science, and CENTRAL (Cochrane Central Register of Controlled Trials) databases was designed and conducted in accordance with PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines. Eligible studies included patients with confirmed adhesions after HA that reported one or more of the following: (1) diagnostic procedures and criteria used; (2) indications for and details surrounding surgical management; and (3) clinical outcomes after the operative management of adhesions (e.g., patient-reported outcome measures). RESULTS Nineteen studies involving a total of 4,145 patients (4,211 hips; 38% female sex) were included in this review. The quality of evidence was found to be fair for both comparative studies (mean, 17; range, 13-21) and noncomparative studies (mean, 10; range, 5-12) according to the Methodological Index for Non-randomized Studies (MINORS) instrument, with the level of evidence ranging from IIB to IV. Adhesions were often diagnosed intraoperatively at the time of revision surgery (10 of 19 studies, 53%), with only 3 studies specifying the criteria used to adjudicate adhesions. The most common indication for operative management (i.e., release or lysis of adhesions) was persistent pain (9 of 19, 47%), but this was often grossly stated for revision HA rather than being specific to adhesions. Patient-reported outcome measures were the most reported postoperative outcomes (9 of 19, 47%) and generally showed significant improvement from preoperative assessment across the short-term follow-up period (range, 24.5-38.1 months). There was a paucity of objective measures of clinical improvement (3 of 19, 16%) and of mid- and long-term follow-up (i.e., 5-7 years and ≥10 years, respectively). CONCLUSIONS Despite the growing body of evidence suggesting that adhesions are highly contributory to revision HA, there is ambiguity in the diagnostic approach and indications for operative management of adhesions. Additionally, although the operative management of adhesions after HA has shown satisfactory clinical outcomes in the short term, there is a paucity of research elucidating the mid- to long-term outcomes, as well as minimal use of objective assessment of clinical improvement (e.g., biomechanics). LEVEL OF EVIDENCE Level IV, systematic review of Level II to IV studies.

MEDICINA (KAUNAS, LITHUANIA) 2024; 60:738. [PMID: 38792921 PMCID: PMC11123463 DOI: 10.3390/medicina60050738] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/21/2024] [Revised: 04/25/2024] [Accepted: 04/26/2024] [Indexed: 05/26/2024]
Abstract
Background and Objectives: The number of hip arthroscopy procedures is on the rise worldwide, and awareness regarding proper management of the hip capsule has increased. No capsulotomy shape is agreed upon as a standard approach, with literature supporting both isolated interportal and T-shaped capsulotomies. The aim of this retrospective cohort study is to report the clinical results of a standardized extended interportal capsulotomy (EIPC) during hip arthroscopy. Materials and Methods: Patients operated on between 2017 and 2020 with a hip arthroscopy were eligible. The inclusion criteria were ages 18-60 years, failed non-operative treatment, and at least a 2-year follow-up. Exclusion criteria were bilateral femoroacetabular impingement syndrome (FAS) cases or labral lesions, ipsilateral knee injury, history of ipsilateral hip surgery, and significant spine lesions. Data regarding demographic characteristics such as age, gender, operation date, BMI, but also Beighton score, presence of postoperative pudendal nerve damage, and revision for any reason were gathered from patients' records. All patients were evaluated preoperatively with a visual analog scale (VAS), the Hip Disability and Osteoarthritis Outcome Score (HOOS), and the modified Harris Hip Score (mHHS). Results: Of the 97 patients operated on with a hip arthroscopy between the defined dates, only 90 patients were included. The mean age was 37.9 ± 9.8, and 58.9% of patients were male. The most frequent surgical indication was an isolated FAS lesion (73.3%), followed by FAS associated with a labral tear (12.2%), an isolated labrum tear (10.0%), synovitis (3.3%), and a loose body (1.1%). The mean follow-up for the study cohort was 39.3 months. The majority of the patients had uneventful surgeries (76.7%), while there were three cases of sciatic nerve neuropraxia and 12 cases of pudendal nerve neuropraxia. Two patients underwent revision surgery during the study period. Comparison between preoperative and postoperative clinical scores showed a significant improvement with a final mHHS mean value of 67.7 ± 18.2, an HOOS value of 74.1 ± 13.2, and a low VAS score of 1.3 ± 1.2. Conclusions: A hip arthroscopy procedure with a standardized and unrepaired, extended interportal capsulotomy is a safe procedure with satisfactory mid-term results and high overall patient satisfaction. At a minimum of 2 years and a mean of 39.2 months, patients showed improved clinical scores and a low revision rate.

Abstract
BACKGROUND Management of femoroacetabular impingement (FAI) through an arthroscopic or surgical hip dislocation (SHD) approach has been shown to have similar clinical success and patient-reported outcomes. However, there are limited data comparing functional outcomes. The purpose of this study was to compare gait and functional outcomes of adolescent/young adult patients with FAI treated by either an arthroscopic or open SHD approach. METHODS We identified prospectively enrolled adolescent/young adult patients (≤20 years old) who underwent surgical treatment for FAI through an SHD or arthroscopic approach. Participants were evaluated in a movement science lab preoperatively and postoperatively (minimum 8 months postoperatively) with barefoot walking and a 30-second single-limb balance trial on the affected side. Participants also completed the Harris Hip Score at the same timepoints. Differences from preoperative to postoperative were determined using a paired-samples t test for each surgical technique, and differences between the SHD and arthroscopic groups were determined using an independent samples t test (α=0.05). RESULTS Fifty-five participants (42F, 16.2±1.4 y) were tested and grouped by surgical intervention. The SHD and arthroscopy groups consisted of 28 and 27 participants, respectively, with no significant difference between the SHD and arthroscopic cohorts in age (16.4±1.2 vs. 15.9±1.5 y, respectively, P =0.218) or sex distribution (78.6% vs. 74.1% females, respectively, P =0.75). Each group demonstrated significant postoperative improvement in Harris Hip Score (SHD: 64.8±16.4 to 81.8±17.8; arthroscopy: 57.0±16.7 to 84.7±19.7; preoperatively to postoperatively, respectively, both P <0.001). During gait, increased maximum hip flexion was observed following surgical intervention for the SHD group (32.3±5.7 vs. 36.1±5.2, P =0.003). No other clinically significant changes were detected in the SHD or arthroscopic groups preoperatively to postoperatively in trunk, pelvis, or hip kinematics in the coronal plane. During the balance task, neither cohort demonstrated markers of clinically significant abductor dysfunction. However, post operatively, the arthroscopy group was able to balance longer than the SHD group (18.8±7.8 vs. 14.2±2.7 s, respectively, P =0.008), although no differences were detected in trunk or pelvis position in the coronal plane during balance. CONCLUSIONS Both open SHD and arthroscopic treatment of FAI resulted in improved clinical outcomes with no clinically significant abductor dysfunction 1 year post operatively. However, further study is needed to determine whether more dynamic tasks can potentially elicit subtle differences between the groups. LEVELS OF EVIDENCE Level II-prospective study.

Abstract
PURPOSE To assess the evolution of surgical hip dislocation (SHD) utilization over the past 20 years, concentrating mainly on the patients' population (adults vs. paediatric), the hip conditions treated using this approach, and reporting on complications of this procedure. METHODS This scoping review was conducted according to Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) guidelines. A PubMed database search was performed using specific search terms for articles related to SHD published between January 2001 and November 2022. RESULTS Initial search revealed 321 articles, of which 160 published in 66 journals from 28 countries were eligible for final analysis. The number of publications increased by 10.2 folds comparing the period from 2001 to 2005 with 2018 to 2022. USA and Switzerland contributed to more than 50% of the publications. Case series studies represented the majority of publications (65.6%). Articles including adult patients represented 73.1% of the publications while 10% were on paediatric patients; however, there was 14 folds increase in publications on paediatric patients comparing the first with the last five years. Managing non-traumatic conditions was reported in 77.5% of the articles, while traumatic conditions in 21.9%. Femoroacetabular impingement (FAI) was the most treated non-traumatic condition reported in 53 (33.1%) articles. In contrast, femoral head fractures (FHF) were the most treated traumatic condition, which was reported in 13 articles. CONCLUSION The publications on SHD and its usage for managing traumatic and non-traumatic hip conditions showed an increasing trend over the past two decades from worldwide countries. Its use in adult patients is well established, and its utilization in treating paediatric hip conditions is becoming more popular.

Youm T. Editorial Commentary: In Patients Undergoing Periacetabular Osteotomy for Hip Dysplasia, Whether Combined or Staged, the Labrum Should Be Arthroscopically Repaired. Arthroscopy 2023; 39:1866-1868. [PMID: 37400170 DOI: 10.1016/j.arthro.2023.03.011] [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: 03/19/2023] [Accepted: 03/20/2023] [Indexed: 07/05/2023]
Abstract
Periacetabular osteotomy (PAO) is the gold standard procedure for patients with significant hip dysplasia. Hip arthroscopy is the gold standard procedure for repairing labral tears. In the past, open PAO procedures were performed without any concomitant labral repair surgery with successful outcomes. Nevertheless, with advances in hip arthroscopy, better outcomes can be achieved by repairing the labrum, as well as performing PAO to achieve bony correction of the deformity. Whether staged or combined, hip arthroscopy plus PAO most successfully treats hip dysplasia. Fix the bony deformity, but also fix the structural damage. Repairing the labrum, combined with PAO, will lead to better outcomes.

Incidence of Venous Thromboembolism After Hip Arthroscopy Is Low With or Without Prophylaxis but Risk Factors Include Oral Contraceptive Use, Obesity, and Malignancy. Arthroscopy 2023; 39:981-987.e1. [PMID: 36334853 DOI: 10.1016/j.arthro.2022.10.029] [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: 05/08/2022] [Revised: 09/28/2022] [Accepted: 10/20/2022] [Indexed: 11/18/2022]
Abstract
PURPOSE To determine the incidence of and risk factors for symptomatic venous thromboembolism (VTE) after hip arthroscopy (HA) and thromboprophylaxis prescription utilization for this procedure. METHODS The PearlDiver Mariner database was queried using Current Procedural Terminology codes to identify adult patients (aged ≥ 18 years) who underwent HA between 2010 and 2020. Patient demographic information, including age, oral contraceptive use, and medical comorbidities, as well as perioperative thromboprophylaxis utilization, was recorded using International Classification of Diseases codes and National Drug Codes. The incidence of postoperative VTE within 90 days was determined. Multivariate logistic regression was used to identify predictors of perioperative thromboprophylaxis utilization and risk factors for VTE. RESULTS The queried records identified 60,181 patients who met the inclusion criteria. Of these patients, 367 (0.6%) experienced VTE, including deep venous thrombosis (0.5%) and/or pulmonary embolism (0.2%). Approximately 2.1% of patients used thromboprophylaxis, including aspirin (1.1%), low-molecular-weight heparin (0.9%), and oral factor Xa inhibitors (0.1%). Oral contraceptive pill use (adjusted odds ratio [aOR], 2.16; 95% confidence interval [CI], 1.34-3.46), obesity (aOR, 1.37; 95% CI, 1.05-1.79), and a history of malignancy (aOR, 1.69; 95% CI, 1.12-2.54) were associated with increased odds of experiencing VTE. Perioperative thromboprophylaxis (aOR, 0.52; 95% CI, 0.19-1.39) was not significantly associated with decreased odds of experiencing VTE. However, obesity (aOR, 1.17; 95% CI, 1.00-1.38) and hypertension (aOR, 1.17; 95% CI, 1.02-1.36) were associated with increased odds of thromboprophylaxis prescription utilization. CONCLUSIONS Although the overall risk of symptomatic VTE after HA remains low, oral contraceptive use, obesity, and a history of malignancy are associated with increased odds of thromboembolic events within 90 days. Routine thromboprophylaxis after HA may not be indicated in all patients but can be considered based on patient-specific risk factors. LEVEL OF EVIDENCE Level III, retrospective prognostic comparative trial.

Abstract
PURPOSE To identify the objective criteria and guidelines utilized to determine if patients diagnosed with FAIS can safely return to sport following hip arthroscopy. METHODS The electronic databases MEDLINE Ovid, EMBASE Ovid, and CINAHL were searched to identify eligible studies. Details of study design, sample size, primary diagnosis, and return to sport protocol, duration, and rate were collected by two reviewers, independently. RESULTS Sixty-two studies were selected for full text review of which 14 were included in the final analysis. Of these, nine were clinical commentaries and five were retrospective cohort studies. Three types of rehabilitation guidelines are currently utilized postoperatively: 4-phase, 5-phase, and 6-phase protocols. Although all 14 studies recommend using various types of outcome measures to evaluate a patient's ability to return to sport, only eleven outlined the specific outcome criteria they must achieve to do so. The most utilized outcome measures are the hip outcome score, active and passive range of motion tests, gait analysis, single- and double-leg squat tests, and the Vail hip sports test. Criteria across all three types of protocols was variable, but they all evaluated the same international classification of disability and function constructs described by the World Health Organization: body function, body structure limitations, and activity capacity limitations. CONCLUSIONS There is no consensus on the optimal methods of evaluating a patient's readiness to return to sport after undergoing hip arthroscopy, with most criteria focused on expert opinion. Performance-based return to sport outcome criteria is not clearly defined, and validated outcome measures are not being used for FAIS patients post hip arthroscopy. Lastly, well-conducted prospective cohort studies using validated outcome measures and objective definitions of return to sport are needed to consistently identify signs that are prognostic of safe return to sport.

Abstract
BACKGROUND Femoroacetabular impingement (FAI) is a condition caused by repetitive abutment of a morphologically abnormal proximal femur and/or acetabulum that may result in chondral and labral pathology. An understanding of radiographic parameters associated with successful primary surgery has not been well established. PURPOSE To determine preoperative radiographic parameters that predict reoperation for FAI and correlate radiographic measurements with outcomes in these patients. STUDY DESIGN Case-control study; Level of evidence, 3. METHODS A prospectively collected institutional registry of adolescent patients (age, <19 years) who underwent surgery for FAI (arthroscopic/open) was reviewed. Preoperative standing anteroposterior pelvic radiographs were analyzed for femoroepiphyseal acetabular roof (FEAR) index, as well as lateral center-edge angle (LCEA) and alpha, Tönnis, and Sharp angles. Patient-reported outcomes (PROs) (modified Harris Hip Score, Hip disability and Osteoarthritis Outcome Score) were analyzed preoperatively and at 1- and 2-year followup. Radiographic indication of risk for reoperation was evaluated using receiver operating characteristic (ROC) analysis. Spearman correlation was calculated between radiographic measurements and PROs at 2 years postoperatively. RESULTS A total of 81 patients (91 hips) underwent primary surgery (57 surgical dislocations vs 34 arthroscopies) for FAI. The mean age at time of primary operation was 16.23 years (range, 10.4-19.6 years) (73.6% female). Eleven hips (12.1%) underwent reoperation at a mean of 20.6 months from primary surgery. The LCEA, FEAR index, Tönnis angle, and Sharp angle before index surgery were significantly different (P < .05) between patients who underwent reoperation and those who did not. ROC analysis indicated that LCEA <22°, FEAR index >-8.7°, Tönnis angle >6.0°, and Sharp angle >44° were predictors for increased risk of reoperation. Using the cutoff values from the ROC analysis in this series, 43% of patients with an LCEA ≤22° had a repeat procedure, while only 8% of those with an LCEA >22° had a repeat procedure. Similar trends were seen with the other aforementioned acetabular radiographic measurements (FEAR index, Tönnis angle, Sharp angle). Patients who did not require a reoperation demonstrated significant improvement in all PRO categories from their preoperative to 2-year postoperative visits (P < .0001). CONCLUSION In patients undergoing treatment for FAI, a reoperation was associated with radiographic signs of hip dysplasia, indicating that patients with a shallower acetabulum are at risk for a repeat operation.

Arthroscopy 2023:S0749-8063(23)00182-2. [PMID: 36828155 DOI: 10.1016/j.arthro.2023.02.015] [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: 11/08/2022] [Revised: 02/02/2023] [Accepted: 02/07/2023] [Indexed: 02/26/2023]
Abstract
PURPOSE To systematically review and report the mid- to long-term patient reported outcomes (PROs) following hip labral reconstruction. METHODS A literature search of the Pubmed, Embase, and Cochrane Library databases was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines for clinical studies reporting mid- to long-term PROs at minimum five year follow-up following arthroscopic hip labral reconstruction. A quality assessment was performed using the Methodological Index of Non-Randomized Studies (MINORS) grading system. Data collection included study characteristics, demographics, indications, radiographic metrics, perioperative findings, surgical technique, baseline and most recent PROs, and subsequent surgeries. RESULTS Four studies met inclusion criteria, with 182 hips (age range, 27.9 to 38.7 years) undergoing labral reconstruction in primary and revision hip surgery with minimum five year follow-up. There were three level III studies and one level IV study, with an average MINORS score of 16.6. All studies cited labral tissue characteristics as a factor for surgical indications, including the quality and/or size of the labrum. Three studies performed segmental labral reconstructions, while another study utilized a circumferential technique. Varying grafts were selected, including hamstring autograft/allograft, ligamentum teres autograft, iliotibial band autograft, and tensor fascia lata autograft. All studies demonstrated improved PROs from baseline to most recent follow-up, with four studies reporting modified Harris Hip Score (mHHS) values that increased from baseline (range, 58.9 to 66.8) to most recent follow-up (range, 80.1 to 86.3). After labral reconstruction, rates of revision arthroscopy ranged from 4.8% to 13.3% and conversion to total hip arthroplasty ranged from 1.6% to 27%. CONCLUSION Improved PROs were observed in all studies at minimum 5-year follow-up, suggesting that labral reconstruction can offer durable results beyond short-term follow-up. While surgical indications for all studies included labral tissue characteristics, differing graft selection and surgical techniques were utilized across studies, limiting the ability to determine an optimal treatment approach.

Abstract
BACKGROUND Femoroacetabular impingement (FAI) is common among the active and young population. The present study analysed the rate of return to sport, related influencing factors, and the sport activity level according to the Hip Outcome Score - Sport-Specific Subscale (HOS-SSS). METHODS The literature search was performed in December 2020. All clinical trials investigating HOS-SSS and/or return to sport after arthroscopic treatment for FAI were considered for inclusion. The outcomes of interest were to analyse the rate of return to sport and the sport activity level according to the HOS-SSS in patients who underwent arthroscopic osteoplasty for FAI. RESULTS Data from 41 studies (4063 procedures) were retrieved. A total of 88.75% (581 of 655) of patients returned to sports within a mean of 37.4 ± 16.5 months. The HOS-SSS score improved from 45.0 ± 10.6 to 73.1 ± 9.5 (P < 0.0001) at last follow-up. The following baseline characteristics evidenced positive association with post-operative activity level: lighter weight (P = 0.01), younger age (P = 0.001), Tönnis angle grade I (P = 0.009), greater HHS (P = 0.01), NAHS (P < 0.0001) and HOS-ADL (P = 0.01). CONCLUSION Arthroscopic treatment for FAI resulted in excellent results in terms of return to sport. Moreover, lighter weight and younger age, greater HHS, NAHS, HOS-ADL at baseline were positively associated with post-operative sport activity level. LEVEL OF EVIDENCE IV, systematic review.

Abstract
Surgical hip dislocation (SHD) is a powerful and safe approach used to address pathologic lesions around the hip joint, and therefore, many studies have been conducted in this field. However, no bibliometric studies regarding the global research trend concerning SHD have been studied yet. This study aims to determine the research status in the field of SHD research between 2001 and 2021. The publications related to SHD from 2001 to 2021 were retrieved from the Web of Science Core Collection. Three bibliometric tools were used for this study. The main analyses include publication counts, contributions of countries, institutions, authors, journals and funding agencies, as well as analyses on clustering of references and keywords. In total, 498 articles were identified. The annual publication counts of SHD showed an ascending tendency as a whole. The United States has the most prominent contributions, with the most number of publications and the highest value of H-index. The University of Bern was the organization that produced the most literature. Professors Ganz R, Siebenrock KA, Tannast M, Steppacher SD and Leunig M were the core authors in this field. The most productive journal was Clinical Orthopaedics and Related Research. Burst keyword detection suggested that the following research directions, including 'surgical hip dislocation', 'outcome', 'fixation' and 'pain', are considered the research hotspots and deserve more attention. In conclusion, this is the first bibliometric analysis that provides a comprehensive overview of SHD research, which may assist investigators in exploring new directions for this technique.

Hip arthroscopy for femoroacetabular impingement is associated with significant improvement in early patient reported outcomes: analysis of 4963 cases from the UK non-arthroplasty registry (NAHR) dataset. Knee Surg Sports Traumatol Arthrosc 2023; 31:58-69.

Abstract
PURPOSE Results from recent randomised controlled trials demonstrate the superiority of surgery over physiotherapy in patients with femoroacetabular impingement (FAI) of the hip in early follow-up. However, there is paucity of evidence regarding which factors influence outcomes of FAI surgery, particularly notable is the lack of information on the effect of impingement subtype (cam or pincer or mixed) on patient reported outcomes measures (PROMs). This study aims to evaluate the early outcomes of hip arthroscopy for FAI, and their determinants. METHODS This is a retrospective analysis of prospectively collected data from the UK Non-Arthroplasty Hip Registry (NAHR) of patients undergoing arthroscopic intervention for FAI between 2012 and 2019. The null hypothesis was that there is no difference in PROMs, based on morphological subtype of FAI treated or patient characteristics, at each follow-up timepoint. The outcome measures used for the study were the iHOT-12 score and the EQ5D Index and VAS 6- and 12-month follow-up. RESULTS A cohort of 4963 patients who underwent arthroscopic treatment of FAI were identified on the NAHR database. For all FAI pathology groups, there was significant improvement from pre-operative PROMs when compared to those at 6 and 12 months. Overall, two-thirds of patients achieved the minimum clinically important difference (MCID), and almost half achieved substantial clinical benefit (SCB) for iHOT-12 by 12 months. Pre-operatively, and at 12-month follow-up, iHOT-12 scores were significantly poorer in the pincer group compared to the cam and mixed pathology groups (p < 0.01). Multivariable analysis revealed PROMS improvement in the setting of a higher-grade cartilage lesion. CONCLUSION This registry study demonstrates that hip arthroscopy is an effective surgical treatment for patients with symptomatic FAI and results in a statistically significant improvement in PROMs which are maintained through 12 months follow-up.

Abstract
Background. Femoroacetabular impingement (FAI) is one of the most frequent causes of hip pain and limited hip mobility in young and middle-aged patients. It is a result of repeated injury of hip structures, that leads to degenerative changes in hip labrum, cartilage and subchondral bone and provokes progressive development of hip osteoarthritis.
Aim of study to analyze own experience of treating patients with femoroacetabular impingement and identify factors affecting its outcomes.
Methods. Retrospective, uncontrolled, single-center clinical study included 128 patients with FAI which had 150 surgeries on 149 joints in in the period from 2013 to 2021. All patients underwent physical examination and X-ray diagnostics, their FAI type was identified. The alpha angle of external part of femoral head in anterior-posterior position and in the modified Dunn 45 position, as well as Tonnis angle, lateral central-marginal angle in Ogata modification and the height of articular gap along the lateral (LS) and medial edges (MS) of sclerosed acetabulum part were calculated. The i-HOT-33 and HOS scales were used to assess preoperative status and postoperative results.
Results. The average follow-up period was 3.9 years (SD 1.71; min 1.05 and max 8.16). The study included 55 (43.0%) women and 73 (57.0%) men which underwent 64 (42.7%) and 86 (57.3%) surgeries respectively. The most common types of FAI, according to our data, were mixed type (53% of joints) and сam type (27.5% of joints). Insufficient coverage of the femoral head by the acetabulum (borderline dysplasia) in combination with the сam deformity of the femoral head was observed in 18.1%. Pincer-type FAI was observed in 1.4% of joints. We obtained the worst results with a combination of сam deformity and borderline dysplasia in comparison with cam- and mix-type FAI according to the i-HOT-33 and HOS scales. Patients age, deep cartilage damage, irreparable labrum damage and height decrease of the lateral part of the articular gap determined negative effect on treatment results according to the i-HOT-33 and HOS scales.
Conclusion. Hip arthroscopy showed good short- and midterm outcomes in patients with FAI. Pain syndrome is most often manifested in patients with pathology of hip soft tissue structures concomitant to FAI. The combination of сam deformity and insufficient femoral head coverage, deep cartilage damage and a height decrease of the articular gap are important predictors of poor treatment results.

Abstract
Femoroacetabular impingement (FAI) is a common femoral and/or acetabular abnormality that can cause progressive damage to the hip and osteoarthritis. FAI can be the result of femoral head/neck overgrowth, acetabular overgrowth or both femoral and acetabular abnormalities, resulting in a loss of native hip biomechanics and pain upon hip flexion and rotation. Radiographic evidence can include loss of sphericity of the femoral neck (cam impingement) and/or acetabular retroversion with focal or global overcoverage (pincer impingement). Operative intervention is indicated in symptomatic patients after failed conservative management with radiographic evidence of impingement and minimal arthritic changes of the hip, with the goal of restoring normal hip biomechanics and reducing pain. This is done by correcting the femoral head-neck relationship to the acetabulum through femoral and/or acetabular osteoplasty and treatment of concomitant hip pathology. In pincer impingement cases with small lunate surfaces, reverse periacetabular osteotomy is indicated as acetabular osteoplasty can decrease an already small articular surface. While surgical dislocation is regarded as the traditional gold standard, hip arthroscopy has become widely utilized in recent years. Studies comparing both open surgery and arthroscopy have shown comparable long-term pain reduction and improvements in clinical measures of hip function, as well as similar conversion rates to total hip arthroplasty. However, arthroscopy has trended toward earlier improvement, quicker recovery and faster return to sports. The purpose of this study was to review the recent literature on open and arthroscopic management of FAI.

Abstract
OBJECTIVE Global pincer is a relatively rare form of pincer deformity and is typically associated with technical challenges during surgery. So far, controversy remains whether patients with global pincer have equivalent surgical outcomes compared to patients with focal pincer. This study compares the clinical outcomes of arthroscopic treatment between patients with global pincer femoroacetabular impingement (FAI) and focal pincer FAI in the Chinese population. METHODS Data were retrospectively collected from patients with global and focal pincer FAI who underwent hip arthroscopy with a minimum two-year follow-up between April 2016 and December 2018. Radiographic measurements, arthroscopic procedures, preoperative and postoperative patient-reported outcomes (PROs) including modified Harris hip score (mHHS), hip outcome score-activities of daily living (HOS-ADL), international hip outcome tool-12 (iHOT-12), and visual analogue scale (VAS) scores, rates of revision surgery and conversion to total hip arthroplasty (THA) were recorded. Achievement of minimal clinically important difference (MCID) and patient acceptable symptomatic state (PASS) was compared for the VAS, mHHS, HOS-ADL, and iHOT-12 scores between groups. RESULTS The total of 33 and 167 patients were included in the global and focal group, respectively. There were no intergroup differences in age, gender, body mass index or follow-up times. Lateral center-edge angle (LCEA) was reduced in both groups postoperatively. Both groups demonstrated significant improvements in PROs compared with preoperative levels at the final follow-up. The preoperative scores showed significant differences in terms of mHHS (60.34 vs 62.90, P = 0.031) and HOS-ADL (61.45 vs 64.74, P = 0.022) scores between two groups, and the improvement of HOS-ADL score was significantly higher in global group (P = 0.027). However, the postoperative scores, including VAS, mHHS, HOS-ADL, and iHOT-12 scores, showed no significant differences between two groups. And there were no significant differences in the rate of meeting the PASS and MCID between groups. One (3.0%) in the global group and six (3.6%) patients in the focal group underwent revision arthroscopy respectively, with no significant difference (P = 0.876). There were no conversions to THA in both groups. CONCLUSIONS Arthroscopic management of global pincer FAI can achieve excellent functional scores at minimum 2-year follow-up. The outcomes were similar to focal pincer FAI patients with a low rate of secondary procedure.

Abstract
Aims The primary aim of this study was to determine the ten-year outcome following surgical treatment for femoroacetabular impingement (FAI). We assessed whether the evolution of practice from open to arthroscopic techniques influenced outcomes and tested whether any patient, radiological, or surgical factors were associated with outcome. Methods Prospectively collected data of a consecutive single-surgeon cohort, operated for FAI between January 2005 and January 2015, were retrospectively studied. The cohort comprised 393 hips (365 patients; 71% male (n = 278)), with a mean age of 34.5 years (SD 10.0). Over the study period, techniques evolved from open surgical dislocation (n = 94) to a combined arthroscopy-Hueter technique (HA + Hueter; n = 61) to a pure arthroscopic technique (HA; n = 238). Outcome measures of interest included modes of failures, complications, reoperation, and patient-reported outcome measures (PROMs). Demographic, radiological, and surgical factors were tested for possible association with outcome. Results At a mean follow-up of 7.5 years (SD 2.5), there were 43 failures in 38 hips (9.7%), with 35 hips (8.9%) having one failure mode, one hip (0.25%) having two failure modes, and two hips (0.5%) having three failure modes. The five- and ten-year hip joint preservation rates were 94.1% (SD 1.2%; 95% confidence interval (CI) 91.8 to 96.4) and 90.4% (SD 1.7%; 95% CI 87.1 to 93.7), respectively. Inferior survivorship was detected in the surgical dislocation group. Age at surgery, Tönnis grade, cartilage damage, and absence of rim-trimming were associated with improved preservation rates. Only Tönnis grade was an independent predictor of hip preservation. All PROMs improved postoperatively. Factors associated with improvement in PROMs included higher lateral centre-edge and α angles, and lower retroversion index and BMI. Conclusion FAI surgery provides lasting improvement in function and a joint preservation rate of 90.4% at ten years. The evolution of practice was not associated with inferior outcome. Since degree of arthritis is the primary predictor of outcome, improved awareness and screening may lead to prompt intervention and better outcomes.

Abstract
BACKGROUND Previous studies have demonstrated a clinically impactful change in patients between 1 and 2 years after hip arthroscopy. Assessment of differences in patient-specific factors between patients who remain the same and those who change (ie, either improve or decline) could provide valuable outcome information for orthopaedic surgeons treating those patients. PURPOSE To identify patients who experienced change in functional status between 1 and 2 years after hip arthroscopy for femoroacetabular impingement syndrome and assess differences in patient-specific factors between those who improved, remained the same, or declined in functional status. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Prospectively collected data for patients who underwent hip arthroscopy at 1 of 7 centers were analyzed retrospectively at 1 year and 2 years postoperatively. Patients were categorized as "improved,""remained the same," or "declined" between 1- and 2-year follow-up based on the 12-item International Hip Outcome Tool (iHOT-12) minimal clinically important difference (MCID) value. A 1-way analysis of variance was used to assess differences in iHOT-12 scores, age, body mass index (BMI), alpha angle, and center-edge angle (CEA) between groups. Chi-square analyses were used to assess differences in the proportions of male and female patients in the outcome groups. RESULTS The study included 753 patients (515 women and 238 men), whose mean ± SD age was 34.7 ± 12 years. Average 1-year (±1 month) and 2-year (±2 months) iHOT-12 scores for all patients were 73.7 and 74.9, respectively. Based on the calculated MCID of ±11.5 points, 162 (21.5%) patients improved, 451 (59.9%) remained the same, and 140 (18.6%) declined in status between 1- and 2-year follow-up. Those who improved between 1 and 2 years had lower 1-year iHOT-12 scores (P < .0005). We found no difference in age, BMI, alpha angle, CEA, or sex between groups (P > .05). CONCLUSION Between 1- and 2-year follow-up assessments, 21.5% of patients improved and 18.6% declined in self-reported functional status. Those with iHOT-12 scores indicating abnormal function at 1 year improved beyond the MCID at 2 years follow-up. Thus, any decisions about the failure or success of arthroscopic hip procedures should not be made until at least the 2-year follow-up. Failing to thrive at 1-year follow-up may not accurately predict outcomes at year 2 or beyond. This could potentially decrease the perceived need for revision surgery in patients who do not thrive before 2-year follow-up.

Abstract
Coxa profunda presents a unique challenge in surgical treatment approach given global acetabular overcoverage. Arthroscopic treatment can be fraught with difficulty obtaining hip distraction for safe arthroscopic instrumentation, and limited arthroscopic access may prevent sufficient osseous resection of the excess acetabular rim. Although hip arthroscopy use has increased markedly over the past decades for all types of hip pathology, coxa profunda may represent one unique indication for surgical hip dislocation. This technique describes open surgical hip dislocation, rim resection, femoral osteoplasty, and labral reconstruction using anterior tibialis allograft for coxa profunda with combined-type femoroacetabular impingement syndrome and labral ossification.

Abstract
BACKGROUND Femoroacetabular impingement syndrome (FAIS) has gained vast importance in the last two decades. Multiple studies have shown that if untreated, early osteoarthritis of the hip joint may result. Hip arthroscopy is one of the fastest growing procedures in the orthopedic cosmos, having already replaced the majority of (mini) open techniques in FAIS surgery. However, with the recent remarkable increase in the volume of hip arthroscopies performed worldwide, the number of patients with persistent or recurrent symptoms after FAIS surgery is also growing. PATHOLOGY Potential underlying pathologies are misresection of the bony deformity, insufficiency fracture of the femoral head neck junction or the femoral subchondral head itself (SIFFH), adhesions, failed chondrolabral or capsular treatment, septic arthritis, heterotopic ossification or a wrong indication in the case of osteoarthritis that is already too advanced. Most of these occur more often during the extensive learning curve for hip arthroscopy. DIAGNOSTICS High-quality imaging plays a key role in determining the need for revision surgery vs. further conservative treatment. Therapeutical avenues are shown with the common goal of proper detection and correction of the underlying pathology to address unsatisfactory FAIS treatment outcomes and ensure long-term survival of the native hip joint.

Return to Sport for Professional and Subelite Ice Hockey Players After Arthroscopic Surgery for Femoroacetabular Impingement Syndrome. Orthop J Sports Med 2022; 10:23259671221089984. [PMID: 35571973 PMCID: PMC9092588 DOI: 10.1177/23259671221089984] [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: 12/14/2021] [Accepted: 02/03/2022] [Indexed: 12/02/2022] Open
Abstract
Background: Femoroacetabular impingement syndrome (FAIS) is a common cause of hip pain,
which can prevent ice hockey players from sports participation. Hip
arthroscopy is often performed to relieve pain and enable the player to
return to sport (RTS) and return to performance (RTP). Purpose: To determine the RTS and RTP rates for ice hockey players at the professional
and subelite levels after hip arthroscopy for FAIS. Study Design: Case series; Level of evidence, 4. Methods: High-level ice hockey players who underwent hip arthroscopy for FAIS between
2011 and 2019 were identified using a local hip arthroscopy registry. The
player’s level was confirmed with ice hockey–specific web pages and was
stratified as subelite or professional. Data on the players’ careers were
extracted from these web pages. Player position was divided into
goalkeepers, defensemen, and forwards. Data on participation in games
included the season before onset of symptoms, the season before surgery, and
the first and second seasons after surgery. RTS was defined as returning to
ice hockey after surgery, and RTP was considered as returning to the same
league at a comparable level to before symptoms. Results: A total of 80 ice hockey players were included. Comparing presymptom
performance with the first season after surgery, the RTS rate was 72%, of
which 94% of the players returned to the same or higher level of play.
Comparing the presurgery season with the first season after surgery, the RTS
rate was 78%. At the second season after surgery, 64% of players still
played ice hockey, with a significantly higher return rate among
professional players compared with subelite players (96% vs 69%;
P = .014). Overall, 85% goalkeepers, 74% forwards, and
60% defensemen returned to sport. Only 28% played at least the same number
of games during the first season after surgery as they did during the
presymptom season. Conclusion: High-level ice hockey players who underwent hip arthroscopy for FAIS had a
high RTS rate, in which the majority returned to the same league. However,
only 28% played the same number of games the first season after surgery as
they did at the presymptom level. Professional ice hockey players returned
more frequently than players on the subelite level.

Abstract
Background: The current clinical standard for the evaluation of cam deformity in femoroacetabular impingement syndrome is based on radiographic measurements, which limit the ability to quantify the complex 3-dimensional (3D) morphology of the proximal femur. Purpose: To compare magnetic resonance imaging (MRI)–based metrics for the quantification of cam resection as derived using a best-fit sphere alpha angle (BFS-AA) method and using 3D preoperative-postoperative surface model subtraction (PP-SMS). Study Design: Descriptive laboratory study. Methods: Seven cadaveric hemipelvises underwent 1.5-T MRI before and after arthroscopic femoral osteochondroplasty, and 3D bone models of the proximal femur were reconstructed from the MRI scans. The alpha angles were measured radially along clockfaces using a BFS-AA method from the literature and plotted as continuous curves for the pre- and postoperative models. The difference between the areas under the curve for the pre- and postoperative models was then introduced in the current study as the BFS-AA–based metric to quantify the cam resection. The cam resection was also quantified using a 3D PP-SMS method, previously described in the literature using the metrics of surface area (FSA), volume (FV), and height (maximum [FHmax] and mean [FHmean]). Bivariate correlation analyses were performed to compare the metrics quantifying the cam resection as derived from the BFS-AA and PP-SMS methods. Results: The mean ± standard deviation maximum pre- and postoperative alpha angle measurements were 59.73° ± 15.38° and 48.02° ± 13.14°, respectively. The mean for each metric quantifying the cam resection with the PP-SMS method was as follows: FSA, 540.9 ± 150.7 mm2; FV, 1019.2 ± 486.2 mm3; FHmax, 3.6 ± 1.0 mm; and FHmean, 1.8 ± 0.5 mm. Bivariate correlations between the BFS-AA–based and PP-SMS–based metrics were strong: FSA (r = 0.817, P = .012), FV (r = 0.888, P = .004), FHmax (r = 0.786, P = .018), and FHmean (r = 0.679, P = .047). Conclusion: Strong positive correlations were appreciated between the BFS-AA and PP-SMS methods quantifying the cam resection. Clinical Relevance: The utility of the BFS-AA technique is primarily during preoperative planning. The utility of the PP-SMS technique is in the postoperative setting when evaluating the adequacy of resection or in patients with persistent hip pain with suspected residual impingement. In combination, the techniques allow surgeons to develop a planned resection while providing a means to evaluate the depth of resection postoperatively.

Abstract
We investigated the diagnostic performance of qualitative and quantitative ultrasound criteria for anterosuperior acetabular labral tears (ALTs). In all, 118 people with ALTs (120 hips; case group) and 31 asymptomatic volunteers (42 hips; control group) at Peking University Third Hospital between August 2018 and November 2019 were consecutively included. The labral cleft, labral heterogeneous echogenicity, labral plump morphology, paralabral cyst and labral focal hyperechoic area were used as the qualitative criteria. The anterosuperior labral cross-section area (CSA) was measured as the quantitative criterion. The diagnostic utility of the quantitative and qualitative criteria were explored with magnetic resonance imaging as the diagnostic gold standard. Labral heterogeneous echogenicity was the most sensitive criterion for diagnosing ALTs (up to 80.00%), and the specificity of diagnosing ALTs with paralabral cysts, labral focal hyperechoic area and subcortical cysts of the femoral head and neck was as high as 90.48%-100%. The labral CSA in the case group was 0.27 cm2 (0.21-0.39 cm2), which was significantly larger compared with the control group (0.18 cm2 [0.14-0.23 cm2]; p < 0.001). The area under the receiver operating characteristic curve was 0.802 for diagnosing ALTs according to the labral CSA. The sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy of the combined qualitative criteria for diagnosing ALTs were 90.00%, 71.43%, 90.00%, 71.43% and 85.19%, respectively. Labral heterogeneous echogenicity is a sensitive criterion for diagnosing ALTs, and paralabral cysts, labral focal hyperechoic, area and subcortical cysts of the femoral head and neck are specific criteria. The CSA of the anterosuperior acetabular labrum measured by ultrasound can be used as a quantitative criterion to diagnose ALTs. The combination of labral qualitative criteria provides higher sensitivity and accuracy in diagnosing ALTs.

Abstract
Introduction- Cystic lesions protruding into surrounding anatomical structures may decrease quality of life. Case presentation- In our case, the cyst was located periarticularly which indicated a potential need for open surgery. We used ultrasound-based minimally invasive arthroscopy technique. A 39-year-old-woman's ultrasonographic examination revealed delamination of the acetabular labrum and periarticular cyst located extra-articularly, compressing the iliopsoas muscle. The ultrasound-guided complete removal of the cyst was performed using shaver blade placed into its lumen through the skin incision. The acetabular labral tear was treated with a classic arthroscopy procedure. 5 weeks after the surgery the patient reported no pain and no functional impairment was detected. Conclusion-A well-known ultrasound diagnostic technique can save patients from more invasive procedures and bring benefits to surgeons.

Abstract
BACKGROUND Femoroacetabular impingement (FAI) is a major cause of hip pain in young adults and athletes. Surgical treatment of FAI is recommended in cases of failed nonoperative treatment that have the typical clinical and radiographic findings. At present, the role of risk factors for revision surgery and progression to total hip arthroplasty (THA) in patients with FAI is still unclear. PURPOSE To investigate the possible association between (1) rate of revision and progression to THA and (2) patient characteristics, type of lesion, family history of hip disease, type of intervention, radiographic parameters, physical examination, and pre- and postoperative scores. STUDY DESIGN Systematic review; Level of evidence, 4. METHODS The present systematic review was performed according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. In October 2020, the main online databases were accessed. All articles concerning surgical correction for selected patients with FAI were accessed. Patient characteristics, type of intervention, radiographic parameters, physical examination, and pre- and postoperative scores were assessed. The outcomes of interest were the possible association between these variables and the rate of revision and subsequent progression to THA using a multivariate analysis through the Pearson product-moment correlation coefficient. RESULTS Data from 99 studies (9357 procedures) were collected. The median follow-up was 30.9 months (interquartile range, 24.0-45.0). The mean ± SD age was 33.4 ± 9.3 years; mean body mass index (BMI), 24.8 ± 4.8; percentage right side, 55.8% ± 8.0%; and percentage female sex, 47.5% ± 20.4%. The overall rate of revision was 5.29% (351 of 6641 patients), while the rate of subsequent progression to THA was 3.78% (263 of 6966 patients). Labral debridement (P < .0001), preoperative acetabular index (P = .01), and BMI (P = .03) all showed evidence of a statistically positive association with increased rates of THA. No other statistically significant associations were found between patient characteristics, type of lesion, family history of hip disease, type of intervention, radiographic parameters, physical examination, or pre- and postoperative scores and the rate of revision and/or progression to THA. CONCLUSION Although surgical procedures to treat FAI led to satisfactory outcomes, there was a revision rate of 5.29% in the 9357 procedures in the present systematic review. The rate of progression to THA after a median follow-up of 30 months was 3.78%. Patients who have a higher BMI and/or have a pathologic acetabular index and/or undergo labral debridement during correction of FAI are more at risk for a subsequent THA. We advocate additional education of this patient population in terms of expected outcomes and suggest surgical labral repair instead of debridement if needed.

Abstract
INTRODUCTION With limited evidence on national incidences of hip arthroscopy in the elderly population, the current study aims to investigate trends of primary hip arthroscopies being performed in the elderly population, using the US Medicare database, and determine risk factors for conversion to total hip arthroplasty (THA). METHODS Medicare Standard Analytic Files were queried using CPT codes to retrieve records of primary hip arthroscopies done for degenerative pathology during 2005-2014. Overall and age-stratified trends in the incidence of hip arthroscopy over time were analysed. Kaplan Meier survival curves were used to assess the overall 2-year conversion rate to a THA. Cox regression analysis was implemented to study risk factors for conversion. RESULTS 8100 primary hip arthroscopies for degenerative pathology were performed during 2005-2014. There was a 280% increase in overall incidence of arthroscopy. The most commonly performed arthroscopic procedure was for chondroplasty and/or resection of labrum, with 4712 (58.1%) procedures. Around 18.5% patients underwent arthroplasty within 2 years after primary arthroscopy. Following Cox regression an existing diagnosis of osteoarthritis, ages 65-69, ages 70-74, and arthroscopies done in the West were associated with higher risk of conversion to THA within 2 years. Undergoing a repeat arthroscopy was not significantly associated with a higher risk of conversion. CONCLUSIONS Despite inconclusive clinical evidence, hip arthroscopies are being increasingly used in patients older than 65 in the Medicare population. We conclude that patients in the age bracket of 65-74 years and with a pre-existing diagnosis of osteoarthritis, arthroscopy should be approached with caution.

Abstract
ABSTRACT
The goal of this study was to investigate the sexual and urinary function and any related complications in patients post-hip arthroscopy for the treatment of femoroacetabular impingement (FAI). Data from 214 patients enrolled in the FIRST trial and 110 patients enrolled in the trial’s embedded prospective cohort study (EPIC) were analyzed. EPIC patients either refused to participate in the trial or did not meet the FIRST eligibility criteria. Outcomes included the International Consultation on Continence Questionnaire (ICIQ) for males (ICIQ-MLUTS) and females (ICIQ-FLUTS) and the Female Sexual Function Index (FSFI) and International Index of Erectile Function (IIEF) administered before surgery and at 6 weeks and 12 months. Urinary and sexual function adverse events were recorded up to 24 months. Linear regression analyses were conducted to compare the osteochondroplasty and lavage groups in the FIRST trial and to evaluate age and traction time as prognostic factors among all patients. Longer traction time was associated with a small but statistically significant improvement in urinary voiding function in males at 6 weeks and 12 months (MD (95% CI) = 0.25 (0.12, 0.39), P < 0.001 and 0.21 (0.07, 0.35), P = 0.004), respectively. Mean traction time was 43.7 (± 23.2) min for FIRST trial and 52.8 (± 15.2) min for EPIC cohort patients. Increasing age in male patients was associated with a decrease in urinary continence at 6 weeks (MD (95% CI) = 0.25 (−0.42, −0.09), P = 0.003). FIRST male patients who received osteochondroplasty improved significantly in sexual function at 12 months compared to males in the EPIC cohort (MD (95% CI) = 2.02 (0.31, 3.72), P = 0.020). There was an overall complication rate of 1.2% at 24 months [one urinary infection, two instances of erectile dysfunction (one transient and one ongoing at 24 months) and one reported transient numbness of tip of the penis]. Hip arthroscopy for the treatment of FAI has a low rate of sexual and urinary dysfunction and adverse events.

Abstract
Purpose Dynamic radiostereometric analysis (dRSA) enables precise non-invasive three-dimensional motion-tracking of bones for assessment of joint kinematics. Hereby, the biomechanical effects of arthroscopic osteochondroplasty of the hip (ACH) can be evaluated in patients with femoroacetabular impingement (FAI). The aim was to investigate the pre- and postoperative range of motion (ROM) and the CT bone volume removed (BV) after ACH. We hypothesize increase in ROM 1 year after surgery. Methods Thirteen patients (6 female) with symptomatic FAI were included prospectively. The patient’s hips were CT-scanned and CT-bone models were created. Preoperative dRSA recordings were acquired during passive flexion to 90°, adduction, and internal rotation (FADIR). ACH was performed, CT and dRSA were repeated 3 months and 1 year postoperatively. Hip joint kinematics before, and 3 months and 1 year after ACH were compared pairwise. The bone volume removal was quantified and compared to change in ROM. Results Mean hip internal rotation, adduction and flexion were all unchanged after ACH at 1-year follow-up (p > 0.84). HAGOS scores revealed improvement of quality of life (QOL) from 32 to 60 (p = 0.02). The BV was between 406 and 1783 mm3 and did not correlate to post-operative ROM. Conclusions ACH surgery in FAI patients had no impact of ROM at 1-year follow-up. QOL improved significantly. This indicates that the positive clinical effects reported after ACH might be a result of reduced labral stress and cartilage pressure during end-range motion rather than increased ROM. Level of evidence Therapeutic prospective cohort study, level II.

Orthop J Sports Med 2021; 9:23259671211055723. [PMID: 34901289 PMCID: PMC8655457 DOI: 10.1177/23259671211055723] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/16/2021] [Accepted: 08/04/2021] [Indexed: 11/16/2022] Open
Abstract
Background Subspine impingement (SSI) has been commonly managed with arthroscopic decompression. However, arthroscopic decompression is a demanding technique, as under- or over-resection of the anterior inferior iliac spine (AIIS) could lead to inferior outcomes. An anterior mini-open approach has also been used in the management of femoroacetabular impingement (FAI), and it could provide adequate visualization of the anterior hip joint without a long learning curve. Purpose/Hypothesis The objective of the current study was to compare the outcomes of SSI patients with FAI who underwent arthroscopic subspine decompression and osteoplasty with a group undergoing subspine decompression and osteoplasty using a modified direct anterior mini-open approach. It was hypothesized that there would be no significant difference in outcomes between the groups. Study Design Cohort study; Level of evidence, 3. Methods We reviewed the records of SSI patients who underwent decompression surgery (arthroscopic or mini-open) at our institution from June 1, 2015 to December 31, 2016. Both groups underwent the same postoperative rehabilitation protocol. Preoperative and 2-year postoperative patient-reported outcomes were compared using the modified Harris Hip Score (mHHS), International Hip Outcome Tool-33 (iHOT-33), and Hip Outcome Score-Activities of Daily Living (HOS-ADL). Major and minor complications as well as reoperation rates were recorded. Results Included were 47 patients (49 hips) who underwent subspine decompression using an anterior mini-open approach and 35 patients (35 hips) who underwent arthroscopic subspine decompression. There were no differences in demographic and radiological parameters between the groups, and patients in both groups showed significant improvement in all outcome scores at follow-up. The pre- to postoperative improvement in outcome scores was also similar between groups (mini-open vs arthroscopy: mHHS, 26.30 vs 27.04 [P = .783]; iHOT-33, 35.76 vs 31.77 [P = .064]; HOS-ADL, 26.09 vs 22.77 [P = .146]). In the mini-open group, 10 of the 47 patients had temporary meralgia paresthetica, and fat liquefaction was found in 1 female patient. There were no reoperations in the mini-open group. Conclusion Subspine decompression using the anterior mini-open approach had similar outcomes to arthroscopic decompression in the management of SSI. The lateral femoral cutaneous nerve should be protected carefully during use of the anterior mini-open approach.

Abstract
Femoroacetabular impingement (FAI) is a well-known cause of hip pain and dysfunction in young adults. Surgical treatment has been widely popularized during the past decade. However, most reported results have been limited to short-term and intermediate-term follow-up. The long-term success rate and risk factors for failure are largely unknown. This study aimed to report the long-term (minimum, 10 years) clinical outcomes of surgical treatment of FAI and to describe the clinical and radiographic parameters associated with the failure of treatment involving femoroacetabular osteoplasty (FAO) and labral repair.

Abstract
BACKGROUND AND OBJECTIVE Most of the studies available in the literature related to the treatment of femoroacetabular impingement (FAA) with surgical hip dislocation (CLD) come from Europe and North America. This study describes the short-term results of the LQC technique for treating PFA in a cohort of Colombian patients. PATIENTS AND METHODS We retrospectively analysed 42 cases of PFA treated with LQC from 2006 to 2018. The same orthopaedic surgeon performed all surgeries. Clinical outcome was assessed using the Merle d'Aubigné scores, while radiological assessment was performed using the Tönnis score. RESULTS Fifteen women and 25 men were included in the study, with a mean age of 36.3 years. Two patients had bilateral symptomatic involvement. Of the 42 cases, there were 13 cam type, 11 pincer type and 18 mixed. Preoperatively, 31 hips were classified as poor and moderate, and 11 as good according to the Merle d'Aubigné scale. The preoperative Tönnis radiological classification showed grade 0 in half of the cases. The mean duration of follow-up was 24 months (12 to 37). The final postoperative Merle d'Aubigné scores classified 7 cases as poor or moderate, and 35 as good to excellent (p<0.05). The postoperative Tönnis score showed no significant variation. As complications, one patient had heterotopic ossification, and three had trochanteric nonunion requiring refixation. CONCLUSION Our results suggest that the LQC technique for the treatment of patients with PFA shows satisfactory short-term results with a low complication rate. To our knowledge, this is the first report of results of the surgical procedure for hip dislocation in our region.

Abstract
BACKGROUND Results from systematic reviews and meta-analyses, which have the highest level of evidence (Level I), often drive clinical decision-making and health policy. Often, unpublished trial data are omitted from systematic reviews, raising concerns about the extent of the reliability and validity of results that have been drawn from systematic reviews. We aimed to determine the extent to which systematic review authors include searches of clinical trial registries for unpublished data when conducting systematic reviews in orthopaedic surgery. METHODS Systematic reviews and/or meta-analyses were gathered from the top 5 orthopaedic surgery journals based on the h5-index from Google Scholar Metrics. Systematic reviews that had been published in the Cochrane Database of Systematic Reviews, which requires the inclusion of a clinical trial registry search, served as controls. For the primary outcome, each systematic review from the top 5 orthopaedic journals was screened to determine whether the authors of each study searched for unpublished data in clinical trial registries. We then compared the rate of registry searches with those in the control group. For the secondary analysis, a search of ClinicalTrials.gov was performed for unpublished trial data for 100 randomized systematic reviews. RESULTS All 38 of the Cochrane systematic reviews (100%) included clinical trial registry searches, while the top 5 orthopaedic journals had only 31 of 480 studies (6.5%) that looked at clinical trial registries. The secondary analysis yielded 59 of 100 systematic review articles (59.0%) that could have included unpublished clinical trial data from ≥1 studies to their sample. CONCLUSIONS Systematic reviews that have been published in the top orthopaedic surgery journals seldom included a search for unpublished clinical trial data. CLINICAL RELEVANCE The exclusion of clinical trial registry searches potentially contributes to publication bias within the orthopaedic literature. Moving forward, systematic review authors should include clinical trial registry searches for unpublished clinical trial data to provide the most accurate representation of the available evidence for systematic reviews and meta-analyses.

Nonsurgical Versus Surgical Management of Femoroacetabular Impingement: What Does the Current Best Evidence Tell Us. J Am Acad Orthop Surg 2021; 29:e471-e478.

Abstract
Controversy exists as to the management of femoroacetabular impingement (FAI). When nonsurgical management of symptomatic FAI fails, surgical management is generally indicated. However, many groups with a stake in patient care (particularly payors) have insisted on higher levels of evidence. Recently, there have been several Level I studies published, comparing physical therapy (PT) with hip arthroscopy in the management of symptomatic FAI. All of these studies have used outcomes tools developed and validated for patients with nonarthritic hip pain (the International Hip Outcome Tool). Most highest level evidence confirms that although patients with FAI do benefit from PT, patients who undergo surgical management for FAI with hip arthroscopy benefit more than those who undergo PT (mean difference in the International Hip Outcome Tool 6.8 [minimal clinically important difference 6.1], P = 0.0093). Future large prospective studies are needed to evaluate the effect on the outcomes when there is a delay in surgical management in symptomatic individuals, assess whether FAI surgery prevents or delays osteoarthritis, and determine the role of other advanced surgical techniques.

Abstract
Introduction: In patients with painful hip joint, femoroacetabular impingement is a relatively frequently diagnosed condition.
Study aim: The aim of the study was to present the anatomy, biomechanics and pathomechanism of femoroacetabular impingement, surgical diagnostics and treatment, as well as physiotherapeutic procedures, and to provide answers to the following questions: 1. What are the causes of femoroacetabular impingement development and what is its most common form? 2. What are the clinical and imaging diagnosis of femoroacetabular impingement based on? 3. What are the goals of physiotherapeutic treatment in the treatment of patients with postoperative femoroacetabular impingement?
Material and method: Current professional literature was analysed based on a review of Internet databases, including Pubmed and Google Scholar.
Results: From the abovementioned Internet databases, 30 items from the current profession-al literature on the analysed variables were identified.
Conclusions: The reasons for the development of femoroacetabular impingement are com-plex, including developmental disorders of the hip joint or its chronic overload. Its most common form is mixed type. The basic imaging test used is anterior-posterior X-ray, while clinical assessment is based on anterior-posterior impingement test. Physiotherapy should be individually tailored and focused on improving range of motion and muscle strength of the hip joint.

Abstract
PURPOSE The purpose of this study was to determine the association between operative duration and short-term complications as well as overnight hospital admission following hip arthroscopy. METHODS Hip arthroscopy cases from 2006 to 2016 were retrieved from the National Surgical Quality Improvement Program registry, which prospectively collects 30-day postoperative complications. Patients were stratified into the following groups based on procedure length: group 1 (< 60 min), group 2 (60-120 min), and group 3 (> 120 min). Preoperative characteristics were compared across the cohorts. Multivariate regressions were used to compare complication rates and overnight hospital admission between the three groups. Independent risk factors for overnight hospital admission were characterized. RESULTS A total of 2129 hip arthroscopy cases were identified. Average operative duration was 99.3 ± 55.7 min. As operative time increased, patients were more likely to be younger, male, and had lower American Society of Anesthesiologists (ASA) class (p < 0.001). Body mass index and comorbidity profiles were similar across the patient cohorts, with the exception of hypertension being more prevalent in the shorter operative time cohort (p < 0.001). Patients in group 3 were more likely to stay overnight in the hospital (26.0%) compared to patients in groups 1 (7.7%) and 2 (10.9%), p < 0.001). All postoperative complication rates were otherwise similar between the cohorts. Independent risk factors for overnight hospital admission included increasing operative time (most notably > 120 min relative to < 60 min, relative risk [RR] = 3.53, 95% CI 2.50-5.00, p < 0.001) and increasing ASA classification (most notably ASA III or IV relative to ASA I, RR = 1.64, 95% CI 1.18-2.27; p = 0.013). CONCLUSIONS Increasing operative duration was not associated with increased postoperative complications following hip arthroscopy. However, patients were more than three times likely to stay in the hospital overnight if their surgery was longer than 120 min, relative to cases that were less than 60 min. LEVEL OF EVIDENCE III.

Abstract
PURPOSE The aim of this systematic review was to evaluate the trends in the literature regarding surgical treatment for femoroacetabular impingement syndrome (FAIS) and to present which patient-reported outcome-measures (PROMs) and surgical approaches are included. METHODS This systematic review was conducted with the PRISMA guidelines. The literature search was performed on PubMed and Embase, covering studies from 1999 to 2020. Inclusion criteria were clinical studies with surgical treatment for FAIS, the use of PROMs as evaluation tool and studies in English. Exclusion criteria were studies with patients < 18 years, cohorts with < 8 patients, studies with primarily purpose to evaluate other diagnoses than FAIS and studies with radiographs as only outcomes without using PROMs. Data extracted were author, year, surgical intervention, type of study, level of evidence, demographics of included patients, and PROMs. RESULTS The initial search yielded 2,559 studies, of which 196 were included. There was an increase of 2,043% in the number of studies from the first to the last five years (2004-2008)-(2016-2020). There were 135 (69%) retrospective, 55 (28%) prospective and 6 (3%) Randomized Controlled Trials. Level of evidence ranged from I-IV where Level III was most common (44%). More than half of the studies (58%) originated from USA. Arthroscopic surgery was the most common surgical treatment (85%). Mean follow-up was 27.0 months (± 17 SD), (range 1.5-120 months). Between 1-10 PROMs were included, and the modified Harris Hip Score (mHHS) was most commonly used (61%). CONCLUSION There has been a continuous increase in the number of published studies regarding FAIS with the majority evaluating arthroscopic surgery. The mHHS remains being the most commonly used PROM.

Abstract
Heterotopic ossification (HO) can occur as a complication of various pathologies affecting the hip including trauma, tendon avulsions, chronic injury, spinal cord injury, and soft-tissue disruption caused by surgery. When HO is present alongside intra-articular hip pathology such as femoroacetabular impingement syndrome (FAIS) or labral pathology, consideration should be made to combine the surgical excision of the HO with the FAIS decompression or labral repair if the location and size of the HO is appropriate for arthroscopic excision. Often times, the HO is located in such a position that any central compartment work can be completed before turning to the HO excision. If an open approach is required, the modified Gibson approach can be used for lateral hip access, whereas the Smith-Petersen approach provides anterior hip access. In this Technical Note we discuss arthroscopic techniques for excision of HO in the setting of concomitant FAIS, with discussion of when HO excision occurs in relation to cam decompression and labral repair, and mention tips on how to approach HO excision through an open approach.

Abstract
BACKGROUND A systematic review was conducted comparing patient reported outcomes measures (PROMs), functional scores, and the rate of complications between arthroscopic and open treatment for femoroacetabular impingement (FAI) at mid-term follow-up. MATERIAL AND METHODS This systematic review was performed according to the PRISMA guidelines. The literature search was performed in October 2020. All clinical trials treating FAI using open osteoplasty or arthroscopic surgery were considered for inclusion. Only articles reporting >12 months follow-up were included. RESULTS Data from 97 articles (9981 procedures) were collected. At a mean 19.2 months follow-up there was no difference between the two cohorts. At a mean follow-up of 38 months, the external rotation was increased in the arthroscopic group (P < 0.0001). The modified Harris Hip Score scored greater in favour of the open osteoplasty group (P = 0.04), as did the Hip Outcome Score - Activities of Daily Living subscale (P = 0.01). At a mean 45.1 months the arthroscopic group presented greater external rotation (P < 0.0001) and SF-12 Mental (P = 0.04). The modified Harris Hip Score was greater in favour of the open osteoplasty group (P = 0.03), as was the HOS-ADL (P = 0.01). Regarding complications, the arthroscopic group experienced lower rates of subsequent revisions (P < 0.0001). CONCLUSION Based on the significant reduction of revisions-rate and significant increase in range of motion, arthroscopy treatment for the management of FAI may be recommended.

Abstract
This article provides concise and up-to-date information on the most common hip pathologies that affect adolescent athletes. We cover the evaluation and treatment of avulsion injuries, stress fractures, slipped capital femoral epiphysis (SCFE), femoroacetabular impingement, developmental dysplasia of the hip, Legg-Calve-Perthes disease, and coxa saltans focusing on minimizing advanced imaging and using conservative therapy when applicable. Although this is not an all-encompassing list of disorders, it is key to understand these hip pathologies because these injuries occur commonly and can also have detrimental complications if not diagnosed and addressed early, especially SCFE and femoral neck stress fractures.

Abstract
Introduction: Femoroacetabular impingement is a commonly recognized condition among people with hip pain. Aim: The aim of this study was to assess how arthroscopy and physiotherapy treatment influenced the quality of life and functional condition of patients after arthroscopic femoroacetabular impingement (FAI) surgery. Materials and methods: We examined 19 people for the study and included 12 (6 men and 6 women). Their mean age was 40.1 ± 9.7 years. Manual and digital goniometers were used for the range of motion (ROM) measurements, and a dynamometer for muscle strength was used. Results from the operated limb were compared to the nonoperated healthy limb. We examined the patient’s health and well-being using the Harris Hip Score (HHS) and Short-Form Health Survey (SF-36) scales. The mean follow-up period was 21.2 months. Results: The postsurgery mean range of motion for all movements was lower in the operated limb. Statistically significant differences between limbs in ROM were observed for flexion, abduction, extension, and external rotation. Muscle strength was comparable between hip joints, except extension and adduction, which were statistically significantly weaker. The mean strength of the hip flexors and internal rotators was higher in the operated limb. After surgery, 67% of patients returned to exercise at the same or higher level. The mean HHS results were good, with values of 88.00 ± 11.48. The SF-36 scores were >50. Conclusion: After surgery and physiotherapy of FAI, ROM remained lower in the operated limb. Flexion and rotations remained to cause pain. The strength of flexors and internal rotators improved, and there was a high rate of return to sport.

Abstract
Background Arthroscopic treatment of femoroacetabular impingement syndrome (FAIS) has become a common procedure. However, meaningful long-term clinical outcomes have not been defined. Purpose To define the minimal clinically important difference (MCID), substantial clinical benefit (SCB), and patient acceptable symptomatic state (PASS) for the modified Harris Hip Score (mHHS) at a minimum 10-year follow-up in patients undergoing arthroscopic treatment for FAIS and identify preoperative predictors for achievement of the MCID, SCB, and PASS. Study Design Case-control study; Level of evidence, 3. Methods A consecutive series of patients undergoing arthroscopic treatment for FAIS between 2007 and 2009 with a minimum 10-year follow-up was analyzed. Patient data included patient characteristics, radiographic parameters, and the pre- and postoperative mHHS and visual analog scale (VAS) for pain score. Paired t tests were used to compare the patient-reported outcome measures (PROMs). The MCID was determined by calculating half of the standard deviation, and SCB and PASS were calculated by the anchor method. Correlation and logistic regression analyses were conducted to identify predictors for the achievement of the MCID, SCB, and PASS. Results A total of 44 patients (27 men, 17 women) were included. The mean age and body mass index were 42.2 years (range, 16-67 years) and 22.3 kg/m2 (range, 16.76-29.78 kg/m2), respectively. The MCID, absolute SCB, net change SCB, and PASS of the mHHS were calculated to be 19.6, 90.1, 31.5, and 84.4 points, respectively. Preoperative symptom duration was identified as an independent predictor for the achievement of meaningful clinical outcomes. The median symptom durations for patients who achieved the MCID, absolute SCB, net change SCB, and PASS were 11.7, 9.1, 9.0, and 10.8 months, respectively. The median symptom duration for patients who did not achieve the MCID, absolute SCB, net change SCB, and PASS were 15.8, 17.4, 17.3, and 18.4 months, respectively. No other statistically significant correlations were found. Conclusion The preoperative duration of symptoms was identified as an independent predictor for achievement of the MCID, SCB, and PASS. These findings can be helpful in accelerating the transition to surgical treatment of FAIS.

Abstract
Hip surgical techniques have evolved significantly, transitioning from open techniques to arthroscopic techniques. Hip arthroscopy has many advantages over open techniques, including reduced trauma to surrounding tissues, reduced risk of infection, and improved patient-reported outcome measures. Hip arthroscopic techniques are now commonly used for pathologies such as femoroacetabular impingement (FAI). FAI can include cam, pincer, or mixed impingement. Through hip arthroscopy, FAI may be treated with a femoroplasty and acetabuloplasty along with addressing any labral pathology that may exist. Owing to the capsule playing an integral role in hip stability, surgeons are now mindful of the initial approach and closure on completion of the intra-articular procedure. The most common approach for capsulotomy is the inside-out approach. However, this approach can be difficult in patients with a large pincer deformity. The authors describe an outside-in approach to arthroscopic hip capsulotomy. This capsular approach helps protect the labrum and articular cartilage while preserving capsular tissue.

Abstract
BACKGROUND Improvement in patient-reported outcomes (PROs) has been reported in the short term after hip arthroscopy for femoroacetabular impingement syndrome (FAIS) and labral tear in the setting of acetabular overcoverage. Yet, there is a paucity of information in the literature on midterm PROs. PURPOSE To (1) report minimum 5-year PROs in patients who underwent primary hip arthroscopy for FAIS and acetabular labral tears in the context of acetabular overcoverage and (2) compare outcomes with those of a propensity-matched control group without acetabular overcoverage. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Data were prospectively collected and retrospectively analyzed on all patients who underwent hip arthroscopy for FAIS and labral tears between February 2008 and November 2013. Inclusion criteria were lateral center-edge angle >40° and minimum 5-year follow-up for the modified Harris Hip Score (mHHS), Nonarthritic Hip Score (NAHS), and the Hip Outcome Score-Sports-Specific Subscale (HOS-SSS). Exclusion criteria were previous ipsilateral hip surgery or conditions, active workers' compensation claims, or lack of minimum 5-year outcomes. A 1:1 propensity-matched comparison was made between the study group and a control group without acetabular overcoverage (lateral center-edge angle, 25°-40°) based on age at surgery, sex, body mass index, Tönnis grade, laterality, and follow-up time. The minimal clinically important difference (MCID) was calculated for the mHHS, HOS-SSS, and NAHS. Secondary surgical procedures were recorded. RESULTS A total of 54 patients satisfied the inclusion criteria for the study group, of whom 45 (83.3%; 45 hips) had a minimum 5-year follow-up and were matched without differences in age at surgery, sex, body mass index, or follow-up time. The study and control groups demonstrated significant and comparable improvements for the mHHS (mean ± SD Δ, 24.06 ± 24.19 vs 26.33 ± 17.27; P = .625), NAHS (Δ, 31.22 ± 25.31 vs 27.15 ± 17.61; P = .399), and HOS-SSS (Δ, 33.16 ± 34.73 vs 34.75 ± 26.15; P = .557). The rates for achieving the MCID were similar for the study and control groups for the mHHS (76.7% vs 84.2%; P = .399), HOS-SSS (79.1% vs 75.8%; P = .731), and NAHS (81.4% vs 84.2%; P = .738). Need for revision surgery was similar (P = .748). A lower conversion rate to total hip arthroplasty was reported for the study than for the control group (2.2% vs 15.6%; P = .026). CONCLUSION In the context of FAIS, labral tears, and acetabular overcoverage, patients who underwent hip arthroscopy reported significant improvement in several PROs at minimum 5-year follow-up. Moreover, outcomes were comparable with those of a propensity-matched control group without acetabular overcoverage. Furthermore, the rate of achieving the MCID for the mHHS, HOS-SSS, and NAHS was similar between these groups.

Treatment of femoroacetabular impingement by arthroscopy versus anterior mini-open approach: Case-control study of a continuous series of 91 cases at a mean 4.6 years' follow-up. Orthop Traumatol Surg Res 2020; 106:1575-1580.

Abstract
INTRODUCTION Femoroacetabular impingement is a frequent cause of hip pain, and can be managed by conservative surgery. Many studies assessed postoperative course, but none compared operative techniques within a given population. We therefore conducted a retrospective case-control study comparing the minimally invasive anterior Hueter approach versus arthroscopy, assessing difference in 1) functional gain and 2) complications and 3) analyzing the impact of labral or cartilage lesions on functional scores. HYPOTHESIS Clinical results do not differ between the mini-open and arthroscopic approach. MATERIAL AND METHOD Between 2007 and 2018, 91 hips in 84 patients were treated for femoroacetabular impingement: 69/91 (75.8%) cam effect, 6/91 pincer effect (6.6%) and 16/91 mixed (17.6%). Fifty-five were treated by arthroscopy and 36 by the Hueter mini-open approach. There were 20 female and 71 male hips. Mean age at surgery was 32 years (range, 17-55 years). Potential predictive factors comprised Nötzli alpha angle, labral/cartilage lesion and type of surgery. RESULTS Mean follow-up was 4.6 years (range, 1-16 years), with no loss to follow-up. The arthroscopy and Hueter groups showed no differences in functional improvement on Oxford-12 score (gain, -6.7±5.9 versus -6.2±8.1 (p=0.73), Postel Merle d'Aubigné (PMA) score (gain, 1.3±1 versus 1.1±0.9; p=0.41), operative time (75 versus 67min; p=0.16), or alpha angle correction (-10.9±12.9 versus -9.8±7.1; p=0.22). Complications did not differ: 1/55 severe complications after arthroscopy (1 definitive femoral nerve palsy) versus 4/36 non-severe complications after Hueter (3 cases of dysesthesia in the lateral cutaneous nerve of the thigh, 1 rectus femoris enthesopathy) (p=0.15). Labral lesions (37/91) did not affect clinical outcome: gain, 1.2±1 versus 1.3±0.9 on PMA (p=0.514) and -7.3±6 versus -6±7.3 on Oxford-12 (p=0.366). Cartilage lesions (27/91) were associated with poorer outcome on PMA (gain, 1±1.1 versus 1.3±0.9; p=002) but not on Oxford-12 (gain, -6.1±7.3 versus -6.7±6.6; p=0.288). CONCLUSION Impingement correction by the minimally invasive anterior Hueter approach gave clinical results comparable to those of hip arthroscopy in terms of Oxford and PMA scores, alpha angle correction, operative time and complications. Cartilage lesions were associated with poorer clinical results. LEVEL OF EVIDENCE III; retrospective case-control study.

Abstract
The purpose of this narrative review is to identify the anatomy and relevant blood supply to the femoral head as it pertains to hip arthroscopy and lateral cam morphology. The primary blood supply to the femoral head is the lateral ascending superior retinacular vessels, which are terminal branches of the medial femoral circumflex artery. These vessels penetrate the femoral head at the posterolateral head–neck junction. Surgeons performing posterolateral femoral osteoplasty must respect this vasculature to avoid iatrogenic avascular necrosis (AVN). Avoidance of excessive traction, avoidance of distal posterolateral capsulotomy and avoidance of disruption of the superior retinacular vessels should keep the risk for AVN low. Hip extension, internal rotation and distraction are useful in hip arthroscopy to better visualize lateral/posterolateral cam morphology to facilitate an accurate comprehensive cam correction and avoid vascular disruption.

Abstract
BACKGROUND Ultrasound-assisted measurement of hip flexion has demonstrated that hip flexion has been historically overestimated in men. To our knowledge, assessment of hip flexion in women using similar methods has not been reported. Establishing normative values for hip flexion is vital to aid diagnosis, management, and future research. Therefore, we asked 2 questions: (1) At what range of midsagittal hip flexion do soft-tissue impingement and femoroacetabular abutment occur in asymptomatic young adult women? (2) Do radiographic findings on a supine anteroposterior pelvic radiograph correlate with ultrasound-assisted measurements of hip flexion? METHODS Fifty-five asymptomatic adult women volunteers (107 hips) underwent ultrasound-assisted assessment of hip flexion. Hip flexion was recorded at the initiation of labral contact and at bone-on-bone contact. Recorded motion was correlated with common radiographic measurements of hip morphology as observed on a supine anteroposterior pelvic radiograph. RESULTS The mean age of the subjects was 26 ± 3 years (range, 21 to 35 years), and the mean body mass index was 23 ± 3 kg/m (range, 17 to 31.6 kg/m). Mean impingement-free and maximum midsagittal passive flexion were 72° ± 8° (95% confidence interval [CI], 70° to 74°) and 101° ± 11° (95% CI, 99° to 103°), respectively. There were no significant correlations between radiographic measurements of hip morphology and ultrasound-measured hip range of motion. CONCLUSIONS Observed hip flexion in the asymptomatic hips of young women is substantially less than has been historically reported. Morphologic features that are measurable on anteroposterior pelvic radiographs do not correlate with ultrasound-measured hip flexion. Diagnosis of hip disorders and treatments that are designed to alter hip range of motion should be based on normative data. Future studies regarding surgical restoration and/or preservation of hip flexion should be based on an understanding of normal hip range of motion. CLINICAL RELEVANCE Ultrasound-assisted hip flexion measurement established normative values to guide surgical restoration and/or preservation of hip flexion.
