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

Abstract
BACKGROUND Previous studies evaluating the outcomes of hip arthroscopy for patients with global acetabular overcoverage and focal superolateral acetabular overcoverage suffer from short-term follow-up and inconsistent radiographic criteria when defining these subpopulations of patients with femoroacetabular impingement syndrome (FAIS). PURPOSE To evaluate the intermediate-term postoperative outcomes for patients with FAIS in the setting of global acetabular overcoverage, lateral acetabular overcoverage, and normal acetabular coverage. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Patients undergoing hip arthroscopy for FAIS were enrolled in a prospective cohort study, and those with a minimum follow-up of 5 years were included in this analysis. Patients were grouped based on type of acetabular coverage: global overcoverage (lateral center-edge angle [LCEA] ≥40°, with coxa profunda), lateral overcoverage (LCEA ≥40°, without coxa profunda), and no overcoverage (LCEA <40°). Functional outcomes (modified Harris Hip Score and Nonarthritic Hip Score) and failure of primary hip arthroscopy were compared between groups. RESULTS In total, 94 patients (mean age, 41.9 ± 14.2 years) were included with a mean follow-up duration of 6.1 ± 0.9 years. Of these patients, 40.4% had no acetabular overcoverage, 36.2% had lateral overcoverage, and 23.4% had global overcoverage. There was no difference between groups with respect to percentage of patients who underwent reoperation for either revision arthroscopy or conversion to total hip arthroplasty (28.9% for the normal acetabular coverage group, 29.4% for the lateral overcoverage group, and 31.8% for the global overcoverage group; P = .971). Among patients for whom primary hip arthroscopy did not fail, there was no difference in 5-year functional outcomes between groups. Postoperative LCEA >40° (β = -13.3; 95% CI, -24.1 to -2.6; P = .016), female sex (β = -14.5; 95% CI, -22.7 to -6.2; P = .001), and higher body mass index (β = -1.9; 95% CI, -2.8 to -1.0; P < .001) were associated with worse intermediate-term hip function in terms of modified Harris Hip Score. CONCLUSION There was no difference in functional outcomes or rate of reoperation at a minimum of 5 years postoperatively between those with global acetabular overcoverage, those with regional lateral overcoverage, and those with normal acetabular coverage. Provided that an appropriate acetabuloplasty is performed, there is no evidence to suggest that global acetabular overcoverage portends a worse prognosis than other FAIS subtypes.

Reprint of: Class I Obesity Delays Achievement of Patient-Acceptable Symptom State but Not Minimum Clinically Important Difference or Substantial Clinical Benefit After Primary Hip Arthroscopy for Femoroacetabular Impingement Syndrome. Arthroscopy 2023; 39:1971-1979. [PMID: 37543382 DOI: 10.1016/j.arthro.2023.06.028] [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: 06/28/2022] [Accepted: 01/31/2023] [Indexed: 08/07/2023]
Abstract
PURPOSE To identify differences in the time taken to achieve the minimum clinically important difference (MCID), substantial clinical benefit (SCB), and patient-acceptable symptom state (PASS) following primary hip arthroscopy for the treatment of femoroacetabular impingement syndrome (FAIS) among patients of different body mass index (BMI) categories. METHODS We conducted a retrospective comparative study of hip arthroscopy patients with minimum 2-year follow-up. BMI categories were defined as normal (18.5 ≤ BMI < 25.0), overweight (25.0 ≤ BMI <30.0), or class I obese (30.0≤BMI<35.0). All subjects completed the modified Harris Hip Score (mHHS) prior to surgery and at 6 months, 1 year, and 2 years postoperative. MCID and SCB cutoffs were defined as pre-to-postoperative increases in mHHS by ≥8.2 and ≥19.8, respectively. PASS cutoff was set at postoperative mHHS ≥74. Time to achievement of each milestone was compared using the interval-censored EMICM algorithm. The effect of BMI was adjusted for age and sex using an interval-censored proportional hazards model. RESULTS 285 patients were included in the analysis: 150 (52.6%) normal BMI, 99 (34.7%) overweight, and 36 (12.6%) obese. Obese patients had lower mHHS at baseline (P = .006) and at 2-year follow-up (P = .008). There were no significant intergroup differences in time to achievement for MCID (P = .92) or SCB (P = .69), but obese patients had longer time to PASS than normal BMI patients (P = .047). Multivariable analysis found obesity to be predictive of longer time to PASS (HR = .55; P = .007) but not MCID (HR = 0.91; P = .68) or SCB (HR = 1.06; P = .30). CONCLUSIONS Class I obesity is associated with delays in achieving a literature-defined PASS threshold after primary hip arthroscopy for FAIS. LEVEL OF EVIDENCE Level III, retrospective comparative study.

Saltzman BM. Editorial Commentary: Obesity Is Associated With Lower Hip Function Pre- and Postoperatively and Increased Time to Patient Acceptable Symptom State After Hip Arthroscopy. Arthroscopy 2023; 39:1980-1982. [PMID: 37543383 DOI: 10.1016/j.arthro.2023.03.010] [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: 03/15/2023] [Accepted: 03/17/2023] [Indexed: 08/07/2023]
Abstract
In 2015, worldwide, there were more than 1.9 billion adults classified as having overweight (body mass index [BMI] >25), with 600 million of these individuals meeting the definition of obesity (BMI >30). Hip arthroscopy in patients with obesity can lead to improve outcomes, albeit with lower absolute levels of patient-reported outcome scores and with increased risk of complications and conversion rates to total hip arthroplasty when compared with their counterparts without obesity. Importantly, a significantly longer time to patient acceptable symptoms state achievement is seen for patients with class I obese than patients with normal BMI. Unfortunately, the hip is quite susceptible to the effects of obesity, with greater acetabular depth/deformity, reduced femoral head cartilage, greater forces experienced with ambulation, and a predisposition to femoroacetabular impingement syndrome. Thus, almost 42% of patients operated on in North America for femoroacetabular impingement syndrome are classified as having overweight or obesity. This does not need to deter from the consideration of arthroscopic hip surgery in the population with obesity; rather, it supports a discussion between surgeon and patient on expectations and timeline for improvement.

Low Rates of 5-Year Secondary Surgery and Postoperative Complications After Primary Hip Arthroscopy in More Than 30,000 Patients. Arthroscopy 2023; 39:1639-1648. [PMID: 37286283 DOI: 10.1016/j.arthro.2023.01.100] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/06/2022] [Revised: 12/12/2022] [Accepted: 01/24/2023] [Indexed: 06/09/2023]
Abstract
PURPOSE To evaluate 90-day complications, 5-year secondary surgery rates, and risk factors for secondary surgery following primary hip arthroscopy performed for femoroacetabular impingement and/or labral tears using a large national dataset. METHODS A retrospective analysis was conducted using the PearlDiver Mariner151 database. Patients with International Classification of Diseases, Tenth Revision, diagnosis codes for femoroacetabular impingement and/or labral tear undergoing primary hip arthroscopy with femoroplasty, acetabuloplasty, and/or labral repair between 2015 and 2021 were identified. Those with concomitant International Classification of Diseases, Tenth Revision, codes for infection, neoplasm, or fracture were excluded, as were patients with a history of previous hip arthroscopy or total hip arthroplasty, or age ≥70 years. Rates of complications within 90 days of surgery were assessed. Five-year rates of secondary surgery-revision hip arthroscopy or conversion to total hip arthroplasty-were determined by Kaplan-Meier analysis, and risk factors for secondary surgery were identified by multivariate logistic regression. RESULTS A total of 31,623 patients underwent primary hip arthroscopy from October 2015 to April 2021, with annual volumes ranging from 5,340 to 6,343 surgeries per year. Femoroplasty was the most frequent surgical procedure (performed in 81.1% of surgical encounters), followed by labral repair (72.6%) and acetabuloplasty (33.0%). Ninety-day postoperative complication rates were low, with 1.28% of patients experiencing any complication. The 5-year secondary surgery rate was 4.9% (N = 915 patients). Multivariate logistic regression identified age <20 years (odds ratio [OR] 1.50; P < .001), female sex (OR 1.33; P < .001), class I obesity (body mass index 30-34.9: OR 1.30; P = .04), and class II/III obesity (body mass index ≥35.0: OR 1.29; P = .02) as independent predictors of secondary surgery. CONCLUSIONS In this study of primary hip arthroscopy, 90-day adverse events were low at 1.28%, and the 5-year secondary surgery rate was 4.9%. Age younger than 20 years, female sex, and obesity were risk factors for secondary surgery, suggesting the need for increased surveillance in these patient groups.

Hip Arthroscopy for Femoroacetabular Impingement Syndrome Shows Good Outcomes and Low Revision Rates, With Young Age and Low Postoperative Pain Score Predicting Excellent 5-Year Outcomes. Arthroscopy 2023; 39:285-292. [PMID: 35367300 DOI: 10.1016/j.arthro.2022.03.024] [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: 11/04/2021] [Revised: 01/16/2022] [Accepted: 03/18/2022] [Indexed: 02/02/2023]
Abstract
PURPOSE To evaluate the clinical outcomes of hip arthroscopy for femoroacetabular impingement syndrome (FAIS) and their predictors at a minimum 5 years' follow-up. METHODS We retrospectively analyzed patients with FAIS after first-time unilateral hip arthroscopy between January 2010 and July 2016. Patient-reported outcomes (PROs) included the validated modified Harries Hip Score (mHHS) and Visual Analog Scale for Pain (Pain VAS). We included patients with Tönnis grade 0 or 1 and reported PROs, and excluded patients with previous hip diseases or bilateral symptoms. Bivariate and multivariate analyses were used for data analysis. RESULTS We included 159 patients with a mean follow-up of 6.4 years, aged 36.18 ± 8.61 years, 41.5% female, and a mean body mass index of 23.61 ± 3.45. The mean postoperative mHHS was 88.82 ± 11.60, and the mean Pain VAS was 1.93 ± 1.89, significantly better than before surgery (P < .001). Postoperative alpha angle (P = .003) and lateral center edge angle (P < .001) were significantly decreased. Most patients (83.7%) achieved clinically important improvement based on patient-acceptable symptom state and minimal clinically important difference (MCID). The overall revision surgery rate was 2.5%. There were no conversions to total hip arthroplasty. Bivariate analysis indicated that age (P < .001), preoperative mHHS (P = .002), and postoperative Pain VAS (P <.001) correlated with postoperative mHHS at a minimum 5 years' follow-up. Multivariate regression analysis of MCID showed that age (P <.001), preoperative PROs (P < .01 for both), and postoperative Pain VAS (P < .001) were significant outcome predictors. CONCLUSION Patients with FAIS after first-time unilateral hip arthroscopy showed significant improvement in PROs at mid-term follow-up, with a low revision surgery rate. Young patients and those with low postoperative Pain VAS showed excellent outcomes at a minimum 5 years' follow-up. LEVEL OF EVIDENCE Level IV, retrospective case series.

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

Abstract
BACKGROUND The effect of low body mass index (BMI) on outcomes in female athletes is unknown. PURPOSE (1) To report minimum 2-year patient-reported outcomes and return to sports for high-level female athletes with low BMI undergoing hip arthroscopy for femoroacetabular impingement syndrome and (2) to compare results with those of a propensity-matched control group of high-level female athletes with a normal BMI. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Data were collected on all professional, collegiate, and high school female athletes who had a low BMI and underwent primary hip arthroscopy between September 2009 and March 2017 at our institute. Return-to-sports status and minimum 2-year patient-reported outcomes were collected for the modified Harris Hip Score (mHHS), Nonarthritic Hip Score, Hip Outcome Score-Sport Specific Subscale, and visual analog scale (VAS) for pain. The percentage of patients achieving the minimal clinically important difference (MCID), Patient Acceptable Symptom State (PASS), and maximum outcome improvement satisfaction threshold (MOIST) was also recorded. These patients were propensity matched to high-level female athletes with a normal BMI for comparison. RESULTS A total of 21 high-level female athletes (25 hips) with a mean ± SD follow-up of 58.9 ± 31.5 months were included. They demonstrated significant improvement from preoperatively to latest follow-up for the mHHS, Nonarthritic Hip Score, Hip Outcome Score-Sport Specific Subscale, and VAS (P < .001). When outcomes were compared with those of the control group, female athletes with low BMI demonstrated lower rates of achieving the MCID for the mHHS (54.5% vs 77.4%; P = .041), PASS for the International Hip Outcome Tool-12 (45.5% vs 72.6%; P = .022), and MOIST for the VAS (31.8% vs 56.5%; P = .047). There were no other significant differences in the rate of achieving the MCID, PASS, or MOIST between the groups (P > .05). Female athletes with low BMI also had higher rates of revision when compared with the control group (27.2% vs 10.6%; P = .049), but there were comparable return-to-sports rates (75.0% vs 74.5%; P > .05). CONCLUSION High-level female athletes with low BMI undergoing primary hip arthroscopy for femoroacetabular impingement syndrome demonstrated significant improvement in patient-reported outcomes and acceptable rates of return to play. When compared with a control group with normal BMI, they exhibited higher rates of revision and lower rates of achieving the MCID for the mHHS, PASS for the International Hip Outcome Tool-12, and MOIST for the VAS.

Abstract
BACKGROUND Access to quality health care and treatment outcomes can be affected by patients' socioeconomic status (SES). PURPOSE To evaluate the effect of patient SES on patient-reported outcome measures (PROMs) after arthroscopic hip surgery. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Demographic, radiographic, and intraoperative data were prospectively collected and retrospectively reviewed on all patients who underwent hip arthroscopy for femoroacetabular impingement syndrome (FAIS) and labral tear between February 2008 and September 2017 at one institution. Patients were divided into 4 cohorts based on the Social Deprivation Index (SDI) of their zip code. SDI is a composite measure that quantifies the level of disadvantage in certain geographical areas. Patients had a minimum 2-year follow-up for the modified Harris Hip Score (mHHS), Nonarthritic Hip Score (NAHS), International Hip Outcome Tool-12, and visual analog scale (VAS) for both pain and satisfaction. Rates of achieving the minimal clinically important difference (MCID) and patient acceptable symptom state (PASS) were calculated for the mHHS, NAHS, and VAS pain score. Rates of secondary surgery were also recorded. RESULTS A total of 680 hips (616 patients) were included. The mean follow-up time for the entire cohort was 30.25 months. Division of the cohort into quartiles based on the SDI national averages yielded 254 hips (37.4%) in group 1, 184 (27.1%) in group 2, 148 (21.8%) in group 3, and 94 (13.8%) in group 4. Group 1 contained the most affluent patients. There were significantly more men in group 4 than in group 2, and the mean body mass index was greater in group 4 than in groups 1 and 2. There were no differences in preoperative radiographic measurements, intraoperative findings, or rates of concomitant procedures performed. All preoperative and postoperative PROMs were similar between the groups, as well as in the rates of achieving the MCID or PASS. No differences in the rate of secondary surgeries were reported. CONCLUSION Regardless of SES, patients were able to achieve significant improvements in several PROMs after hip arthroscopy for FAIS and labral tear at the minimum 2-year follow-up. Additionally, patients from all SES groups achieved clinically meaningful improvement at similar rates.

Parameters affecting baseline hip function in patients with cam-derived femoroacetabular impingement syndrome: data analysis from the German Cartilage Registry. J Orthop Traumatol 2021; 22:32. [PMID: 34350524 PMCID: PMC8339184 DOI: 10.1186/s10195-021-00596-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/17/2021] [Accepted: 07/25/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Using the database of the German Cartilage Registry (KnorpelRegister DGOU), this study aims to present patient- and joint-related baseline data in a large cohort of patients with cam-derived femoroacetabular impingement syndrome (FAI) and to detect symptom-determining factors. MATERIALS AND METHODS Requiring cam morphology as the primary pathology, 362 patients were found to be eligible for inclusion in the study. The assessment of preoperative baseline data was performed using the patient-reported outcome measure-International Hip Outcome Tool (iHOT-33). Descriptive statistics were performed to present baseline data. Univariate and multiple regression with post hoc testing were used to identify patient- and joint-related factors that might affect the preoperative iHOT-33 and its subscores, respectively. RESULTS The study collective's mean age was 36.71 ± 10.89 years, with 246 (68%) of them being male. The preoperative mean iHOT-33 total was 46.31 ± 20.33 with the subsection "sports and recreational activities" presenting the strongest decline (26.49 ± 20.68). The parameters "age," "sex," "body mass index" (BMI), and the confirmation of "previous surgery on the affected hip" were identified to statistically affect the preoperative iHOT-33. In fact, a significantly lower mean baseline score was found in patients aged > 40 years (p < 0.001), female sex (p < 0.001), BMI ≥ 25 kg/m2 (p = 0.002) and in patients with previous surgery on the affected hip (p = 0.022). In contrast, the parameters defect grade and size, labral tears, and symptom duration delivered no significant results. CONCLUSIONS A distinct reduction in the baseline iHOT-33, with mean total scores being more than halved, was revealed. The parameters "age > 40 years," "female sex," "BMI ≥ 25," and confirmation of "previous surgery on the affected hip" were detected as significantly associated with decreased preoperative iHOT-33 scores. These results help to identify symptom-defining baseline characteristics of cam-derived FAI syndrome. TRIAL REGISTRATION The German Cartilage Registry is conducted in accordance with the Declaration of Helsinki and registered at germanctr.de (DRKS00005617). Registered 3 January 2014-retrospectively registered. The registration of data was approved by the local ethics committees of every participating institution. Primary approval was given by the ethics committee at the University of Freiburg (No. 105/13). https://www.drks.de/drks_web/navigate.do?navigationId=trial.HTML&TRIAL_ID=DRKS00005617.

Abstract
OBJECTIVE To investigate clinical outcomes after arthroscopic labral preservation surgery for femoroacetabular impingement (FAI) in the presence of osteoarthritis (OA) compared with FAI without significant OA. DESIGN Retrospective case-control study. SETTING Department of Orthopaedic Surgery and Sports Medicine, Hospital of Academic Institute. PATIENTS Femoroacetabular impingement patients (n = 97; ≥35 years) undergoing arthroscopic FAI correction with labral preservation surgery from March 2009 to April 2014 were enrolled in this study. INTERVENTIONS Patients were divided into 2 groups: FAI group (79 patients), with Tonnis grade 0 or 1, and FAI + OA group (18 patients), with Tonnis grade 2 or 3. MAIN OUTCOME MEASURES We examined the clinical outcomes using the Modified Harris Hip Score (MHHS), Nonarthritic Hip Score (NAHS), and the conversion rate to total hip arthroplasty (THA). RESULTS No significant differences existed between the 2 groups with respect to age, sex, follow-up period, or preoperative MHHS or NAHS. The mean MHHS and NAHS at the final follow-up were significantly lower in the FAI + OA group than in the FAI group. There was a significant difference in the rate of conversion to THA and failure between the 2 groups (THA 5% vs 50%) (failure 15% vs 67%). CONCLUSION Patients with FAI in the presence of OA did not improve after arthroscopic labral preservation surgery and had a high conversion rate to THA. LEVEL OF EVIDENCE Level III.

Abstract
BACKGROUND Femoral torsion imaging measurements and classifications are heterogeneous throughout the literature, and the influence of femoral torsion on clinically meaningful outcome improvement after hip arthroscopy for femoroacetabular impingement syndrome (FAIS) has not been well studied. PURPOSE To (1) perform a computed tomography (CT)-based analysis to quantify femoral torsion in patients with FAIS and (2) explore the relationship between the orientation and magnitude of femoral torsion and the propensity for clinically meaningful outcome improvement after hip arthroscopy. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Consecutive patients who underwent hip arthroscopy for FAIS between January 2012 and April 2018 were identified. Inclusion criteria were the presence of preoperative CT imaging with transcondylar slices of the knee and minimum 2-year outcome measures. Exclusion criteria were revision hip arthroscopy, Tönnis grade >1, congenital hip condition, hip dysplasia (lateral center-edge angle <20°), and concomitant gluteus medius or minimus repair. Torsion groups were defined as severe retrotorsion (SR; <0°), moderate retrotorsion (MR; 0°-5°), normal torsion (N; 5°-20°), moderate antetorsion (MA; 20°-25°), and severe antetorsion of antetorsion (SA; >25°). Treatment did not differ based on femoral torsion. Patient characteristics and clinical outcomes were analyzed, including the Hip Outcome Score-Activities of Daily Living (HOS-ADL), Hip Outcome Score-Sports Subscale (HOS-SS), modified Harris Hip Score (mHHS), international Hip Outcome Tool (iHOT-12), visual analog scale (VAS) for pain, and VAS for satisfaction. Achievement of the minimal clinically important difference (MCID) and patient acceptable symptom state (PASS) by torsion stratification was analyzed using the chi-square test. Inter- and intrarater reliabilities for CT measurements were 0.980 (P < .001) and 0.974 (P < .001), respectively. RESULTS The study included 573 patients with a mean ± SD age and body mass index of 32.6 ± 11.8 years and 25.6 ± 10.6, respectively. The mean ± SD femoral torsion for the study population was 12.3°± 9.3°. After stratification, the number of patients within each group and the mean ± SD torsion for each group were as follows: SR (n = 36; -6.5°± 7.1°), MR (n = 80; 2.8°± 1.4°), N (n = 346; 12.3°± 4.1°), MA (n = 64; 22.2°± 1.4°), and SA (n = 47; 30.3°± 3.7°). No significant differences in age, body mass index, sex, tobacco use, workers' compensation status, or participation in physical activity were observed at baseline. No significant differences were seen in pre- and postoperative VAS pain, mHHS, HOS-ADL, HOS-SS, iHOT-12, or postoperative VAS satisfaction among the cohorts. Furthermore, no statistically significant differences were found in the proportion of patients who achieved the MCID or the PASS for any outcome among the groups. CONCLUSION The orientation and severity of femoral torsion at the time of hip arthroscopy for FAIS did not influence the propensity for clinically significant outcome improvement.

Hip arthroscopy and T-shaped capsular plication for the treatment of borderline dysplasia: a minimum 2-year follow-up. EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY AND TRAUMATOLOGY 2021; 32:449-458. [PMID: 34009474 DOI: 10.1007/s00590-021-02997-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/03/2020] [Accepted: 04/18/2021] [Indexed: 10/21/2022]
Abstract
PURPOSE The aim of the study was to evaluate the clinical outcomes of patients treated arthroscopically for symptomatic borderline dysplasia of the hip (BHD) with a T-shaped capsular plication, with a minimum follow-up of 24 months. METHODS Twenty-seven patients who had undergone hip arthroscopy and T-shaped capsular plication for symptomatic BHD were included in the study. All patients were clinically evaluated prior to surgery (T0) and at two consecutive follow-ups (T1: 12 ± 1.2 months; T2: 52.0 ± 23.2 months) using the visual analogue scale (VAS) pain score, the Hip Outcome Score in activities of daily living (HOS-ADL) and sport-specific subscale (HOS-SSS), the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and Short Form-12 in its physical (PCS) and mental component scores (MCS). We also evaluated the presence of correlations and analysed the possible differences between subgroups. RESULTS We found a significant difference for HOS-ADL, HOS-SSS, VAS and WOMAC with the Friedman test for repeated measures through time points (p < 0.0001), but not for MCS. All clinical scores reported a significant improvement compared to the previous time point (p < 0.05), with the exception of HOS-SSS, for which p = 0.2570 between T1 and T2. The body mass index was positively correlated with preoperative VAS (R = 0.42857; p = 0.0257) and negatively correlated with PCS at T0 (R = - 0.40999; p = 0.0337) and with PCS (R = - 0.40491; p = 0.0362), MCS (R = - 0.45939; p = 0.0159) and WOMAC (R = - 0.40573; p = 0.0216) at T2. No complications were reported in our cohort. CONCLUSIONS The results of the current study confirm that patients with intra-articular hip pathology and concomitant BHD (LCEA 20°-25°) can benefit from arthroscopic treatment and that T-shaped capsular plication is one of the available options. Orthopaedic surgeons specialising in hip arthroscopy should consider arthroscopy for the treatment of symptomatic BHD for stabilising and strengthening the joint. Future studies should focus on finding out which type of patients can benefit most from this procedure. LEVEL OF EVIDENCE IV Prospective Case Series.

Abstract
PURPOSE The aim of this study was to systematically review the existing literature comparing the postoperative outcomes after following hip arthroscopy in obese and non-obese patients. METHODS Studies comparing the outcomes following hip arthroscopy of obese and non-obese patients were systematically identified via a computer-assisted literature search of Pubmed (Medline), EMBASE, and Cochrane Library using the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines. Studies comparing the outcome of hip arthroscopy in different body mass index (BMI) groups were included. Data including patient-reported outcome measures (PROMs), revision arthroscopy rate, conversion rate to total hip arthroplasty (THA), and complications were collected. The methodological index for non-randomized studies (MINORS) and Newcastle-Ottawa Scale (NOS) were used to assess the quality of each study quality. The effect of heterogeneity was quantified by calculating the I2 value. RESULTS A total of eight studies were finally included in the qualitative analysis, and three studies of high quality involving 373 hips were included in the quantitative assessment. All the studies defined obesity as a BMI of ≥ 30 kg/m2. The modified Harris Hip Score and the Non-Arthritic Hip Score were 5.1 (95% CI 1.1-9.1) and 9.0 (95% CI 5.0-13.1) points lower, respectively, in the obese group than in the non-obese group. The pooled odds ratios were 1.2 (95% CI 0.5-2.7) for revision arthroscopy, 2.4 (95% CI 1.3-4.6) for conversion to THA, and 3.2 (95% CI 1.2-8.6 for complications in favor of the non-obese group. The heterogeneity was low in all outcome assessments (I2 0-18%). CONCLUSION Obese patients had significantly lower PROMs than non-obese patients following hip arthroscopic surgery, and the THA conversion and complication rates were 2.4 times and 3.2 times higher, respectively. Understanding the effect of obesity on hip arthroscopy will allow appropriate surgical indications for surgery to be further refined and help obese patients to understand their individual risk profile.

Orthop Traumatol Surg Res 2021; 107:102767. [PMID: 33333273 DOI: 10.1016/j.otsr.2020.102767] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/14/2020] [Revised: 08/19/2020] [Accepted: 09/18/2020] [Indexed: 02/08/2023]
Abstract
BACKGROUND Hip arthroscopy is a surgical procedure that is becoming more and more prevalent in France. Even though indications are now well-established little is still known about patient outcomes. Therefore, the purpose of our retrospective study was to: (1) describe the circumstances in which hip arthroscopies are being performed; (2) study arthroscopy and arthroplasty reoperation rates; (3) assess the incidence of readmissions for complications. HYPOTHESIS Hip arthroscopy in France produced similar results to those observed in other countries. MATERIALS AND METHODS We conducted a cohort study from January 2008 to December 2014 in the French population using the national hospital discharge database called "Programme de médicalisation des systèmes d'information (PMSI)." We included all admissions that had a hip arthroscopy code and analyzed readmissions for conversion to hip arthroplasty, revision hip arthroscopy and complications (without being able to provide detailed descriptions). Risk factors associated with conversion, revision and readmission for complications were studied after performing a population analysis. RESULTS A total of 3,699 patients were included over a period of seven years. The mean age was 40 years, with women being significantly older (mean age of 43 years) than men (38 years) (p<0.05). The number of procedures increased from 240 in 2008 to 702 in 2014. Synovectomies (67.9%; 2514/3699) and surgical bone procedures (acetabuloplasty or femoroplasty) (47.3%; 1751/3699) were the main procedures performed during the primary arthroscopy. In total, 410 patients underwent a conversion to arthroplasty, 231 patients had a revision arthroscopy, and 126 patients suffered a complication. Five years after the index procedure, the conversion rate was 16.3%, revision rate was 8.2%, and readmission rate for a postoperative complication was 5%. The main risk factor associated with conversions was [Hazard ratio (HR) and 95% Confidence Index (CI)] an age between 40 and 79 years during the first arthroscopy [3.04 (2.40; 3.87) compared with the reference class of 25-39 years]. Patients between ages 16 to 24 years during the first arthroscopy (0.35 [0.20; 0.61] compared with the reference class of 25-39 years) had a decreased risk of conversion (HR and 95% CI). The main risk factors associated with revisions were: synovectomies [1.90 (1.34; 2.70)] and surgical bone procedures on the femoral neck and/or the acetabulum [1.82 (1.36; 2.4)]. The risk factor associated with complication-related readmissions was an age greater than 40 years [2.23 (1.43; 3.49)]. CONCLUSION Unlike the international literature, our study population was largely male. The rates of revision (8.2% after five years) and conversion to arthroplasty (16.3% after five years) were relatively low and comparable to the different international studies. This procedure, which is not widely performed, is growing in popularity, has low morbidity and remains an interesting approach given the revision and conversion rates after five years. The implementation of specific coding for arthroscopic hip procedures and the pathologies to be treated seems warranted. LEVEL OF EVIDENCE IV; descriptive epidemiological study.

Abstract
BACKGROUND Although hip arthroscopy has been shown to have favorable results, there is a paucity of literature describing predictive factors of 5-year clinical outcomes. PURPOSE To identify predictive factors of midterm outcomes after hip arthroscopy in a cohort of 1038 patients whose outcomes at minimum 2-year follow-up were previously reported. In addition, to provide a comparison of short- and midterm predictive factors in outcome measures after hip arthroscopy. STUDY DESIGN Case-control study; Level of evidence, 3. METHODS Data were prospectively collected and retrospectively reviewed on all patients undergoing hip arthroscopy between February 2008 and June 2012. Patients were included if they had minimum 5-year follow-up on 2 patient-reported outcomes: Nonarthritic Hip Score (NAHS) and modified Harris Hip Score. Patients were excluded if they had any previous ipsilateral hip conditions. Using bivariate and multivariate analyses, we analyzed the effect of 36 pre- and intraoperative variables on the NAHS, modified Harris Hip Score, and conversion to total hip arthroplasty. RESULTS A total of 1038 patients met the inclusion criteria for the 2-year study, and 860 met our listed inclusion criteria for the 5-year study. The mean follow-up time was 62.0 months (range, 60.0-120.0 months). The bivariate analysis identified 10 variables (4 categorical and 6 continuous) that were predictive of 5-year postoperative NAHS. For the multivariate analysis, 7 variables were identified as being significant: preoperative NAHS, body mass index (BMI), age, lateral joint space, alpha angle, revision hip arthroscopy, and acetabular microfracture. These 7 variables were also predictive in the bivariate analysis. Age, BMI, revision hip arthroscopy, Tönnis grade, sex, trochanteric bursectomy, femoral head cartilage damage, and acetabular inclination were significant predictors of conversion to total hip arthroplasty. CONCLUSION This study reports favorable midterm clinical outcomes in the largest cohort of hip arthroscopies with minimum 5-year follow-up in the literature to date. Seven variables were identified as being significant predictors of postoperative NAHS in the bivariate and multivariate analyses: preoperative NAHS, BMI, age, lateral joint space, alpha angle, revision hip arthroscopy, and acetabular microfracture. Of these, preoperative NAHS, BMI, age, and revision hip arthroscopy were predictive of 2- and 5-year postoperative NAHS. These predictive factors may prove useful to clinicians in determining indications for hip arthroscopy and counseling patients on its expected outcomes.

Abstract
BACKGROUND Significant short-term improvements in function and pain after arthroscopic management of femoroacetabular impingement syndrome (FAIS) have been demonstrated regardless of mass index (BMI). No studies have reported the influence of obesity on mid- to long-term outcomes. PURPOSE To evaluate the effect of BMI class on 5-year patient outcomes after arthroscopic treatment of FAIS. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS A retrospective review of a prospective database was performed to identify patients who underwent arthroscopic treatment for FAIS. A matched-pair analysis for age and sex was performed in a 1:1:2:3 fashion for morbidly obese (BMI ≥35), obese (BMI = 30-34.9), overweight (BMI = 25-29.9), and normal weight (BMI = 18.5-24.9) patients, respectively. Patient characteristics, imaging, Hip Outcome Score Activities of Daily Living (HOS-ADL) and Sports Subscale (HOS-SS) scores, modified Harris Hip Score (mHHS), and pain scores were recorded preoperatively, with the same outcome scores recorded at 5 years postoperatively, along with satisfaction scores. Standardized modern hip arthroscopy, with labral repair, acetabuloplasty, femoroplasty, and capsular plication followed by formalized rehabilitation, was performed for all patients. Absolute outcomes along with change in outcomes were assessed between BMI groups. A between-group analysis was also conducted evaluating achievement of the minimal clinically important difference (MCID), patient acceptable symptomatic state (PASS), and substantial clinical benefit (SCB) for any outcome score. A multivariable analysis was additionally included to evaluate outcomes adjusting for known confounding variables. RESULTS A total of 140 patients with mean follow-up of 62.1 ± 6.5 months were identified: 20 morbidly obese, 20 obese, 40 overweight, and 60 normal weight. There were significant improvements for HOS-ADL, HOS-SS, and mHHS scores in the normal (all P < .0001) and overweight groups (all P < .0001), mHHS in the obese group (P = .0275), and no significant improvement in functional scores in the morbidly obese group (P > .05). Compared with normal controls, multivariable analysis, adjusting for confounders, showed similar improvement in HOS-ADL for patients in the overweight and obese groups, HOS-SS for patients in the overweight group, and mHHS for patients in the overweight and obese groups (all P > .05). All groups showed significant improvement in pain scores (all P < .01) that were not significantly different between groups in multivariable analysis (all P > .05). Obese BMI was associated with a 54.9-point decrease in 5-year HOS-SS, and morbidly obese BMI was associated with a 27.3, 35.0, and 23.7-point decrease in 5-year HOS-ADL, HOS-SS, and mHHS, respectively (all P < .05). Regarding surgical benefit in comparison with normal weight patients, patients in the overweight and obese groups were as likely to achieve MCID (reciprocal odds ratio [ROR]: 1.5 and 1.2, respectively, both P > .05), but patients in the morbidly obese group were not. All groups were significantly less likely than the normal weight group to achieve PASS (ROR: overweight 5.2, obese 14.1, morbidly obese 13.0; all P < .05) and SCB (ROR: overweight 3.9, obese 7.8, morbidly obese 20.3; all P < .05). CONCLUSION There were significant improvements in at least 1 outcome score across all BMI groups with arthroscopic treatment of FAIS. While the normal weight patients demonstrated universal improvement in all patient-reported outcomes and significantly greater likelihood of achieving PASS and SCB, the higher BMI groups still demonstrated significant improvement in function and pain, except for the morbidly obese group. Patients with morbid obesity demonstrated long-term pain improvement, although they did not experience functional improvement.

Abstract
Sports medicine surgeons sometimes encounter morbidly obese athletes with femoroacetabular impingement, such as Sumo wrestlers. In such cases, traditional arthroscopic equipment will not reach the joint. This case report describes the use of a cystoscope to perform arthroscopy to treat borderline developmental dysplasia of the hip combined with cam impingement in a morbidly obese athlete. The cystoscope enables hip arthroscopy to be performed when traditional instruments are not of sufficient length to access the hip and/or an extra-long arthroscope is not available. The use of the cystoscope provides a practical, feasible and minimally invasive option to treat non-arthritic intraarticular hip pathology in the morbidly obese or extremely muscular athletes.

Abstract
Pipkin type IV femoral head (FH) fracture-dislocations are usually treated via open surgery. There are many surgical approaches for the treatment of this difficult fracture depending on the fracture pattern. Obesity presents another challenging problem in surgical treatment and sometimes leads to a poorer outcome. We discuss herein a patient of a high body mass index (BMI) with a Pipkin type IV FH fracture who underwent open reduction internal fixation (ORIF) of anacetabular fracture with reconstruction plates and hip arthroscopy-assisted fixation of the FH fracture with two Herbert screws via the posterior approach. The intra-articular osteochondral loose bodies were excised by hip arthroscopy simultaneously. The joint congruency and screw positions were checked during surgery by arthroscopy. After 6 months, clinical and computed tomography (CT) follow-ups showed excellent results. The patient of a high BMI recovered immediately and had a satisfactory short-term outcome after hip arthroscopy-assisted surgery. We concluded that hip arthroscopy-assisted surgery is a viable option for the treatment of Pipkin type IV FH fracture-dislocations.

Abstract
Hip arthroscopy for femoral and acetabular pathologies has increased dramatically. However, there is little literature analyzing procedures as predictors of revision arthroscopy or arthroplasty. From February 2008 to November 2015, patients undergoing hip arthroscopy for a labral tear with minimum 2-year follow-up and between 18 and 60 years old were retrospectively reviewed. Those with previous surgeries, Tönnis grade greater than 1, and previous hip conditions were excluded. Follow-up was obtained for 1118 patients (1249 hips; 81.7%) with a mean age of 38.7 years (range, 18.0-60.0 years), mean body mass index of 26.4 kg/m2 (range, 16.3-48.9 kg/m2), and mean follow-up of 50.2 months (range, 24.0-111.9 months). A total of 122 (9.8%) patients converted to total hip arthroplasty (mean, 35.3 months; range, 1.4-95.2 months). Multivariate analysis for predictors of total hip arthroplasty found age at surgery (hazard ratio, 1.064/y; P<.05), body mass index (nonlinear; P<.05), labral debridement (HR, 1.558; P=.03), and notchplasty (HR, 2.128; P<.05), with trochanteric bursectomy (HR, 0.367; P<.05) identified as associated with higher survivorship. A total of 124 (9.9%) patients underwent revision hip arthroscopy at a mean of 21.7 months (range, 0.10-83.3 months). Multivariate analysis for predictors of revision surgery found workers' compensation (HR, 3.352; P<.05), capsular repair (HR, 1.950; P<.05), and femoral head microfracture (HR, 2.844; P=.04) to be significant, with age at date of surgery (HR, 0.973/y; P<.05) and femoral head chondroplasty (HR, 0.241; P=.05) associated with higher survivorship. Understanding risk factors for conversion to total hip arthroplasty or revision is paramount during discussions with patients. [Orthopedics. 2020;43(3):173-181.].

Abstract
BACKGROUND As health care moves toward a value-based payment system, it will be important that patient-reported outcome measures (PROMs) define variations in outcome over a follow-up period that allows a patient to achieve maximal improvement. Although there is evidence to support the use of PROMs to assess postoperative outcomes after hip arthroscopy, there is limited information available to assess for variations in outcome at a 2-year follow-up interval. PURPOSE To identify substantial clinical benefit (SCB) and patient acceptable symptom state (PASS) cutoff scores for the 12-item International Hip Outcome Tool (iHOT-12) that define patient status across a spectrum of potential outcomes after hip arthroscopy at a 2-year follow-up interval. STUDY DESIGN Cohort study (diagnosis); Level of evidence, 2. METHODS These data were collected from a research registry of patients having hip arthroscopy for femoroacetabular impingement and/or chondrolabral pathology. On initial assessment and 2 years (±2 months) postoperatively, patients completed the iHOT-12, and categorical self-rating of function. They also completed a visual analog scale of postoperative satisfaction. Receiver operator characteristic analysis was performed to determine absolute SCB iHOT-12 scores associated with an "abnormal,""nearly normal," or "normal" self-report of function, and PASS scores for those reporting at least 50%, at least 75%, or 100% satisfaction with their surgery. RESULTS Out of 723 eligible patients, 658 (91%) met the inclusion criteria. The patients consisted of 462 (70%) women and 196 (30%) men, with a mean age of 35.3 years (SD, 13 years) and mean follow-up of 722 days (SD, 69 days). Absolute SCB and PASS iHOT-12 scores ranging from 38 to 86 were accurate in identifying those who had abnormal, nearly normal, and normal self-reported function and were at least 50%, at least 75%, and 100% satisfied with surgery. The areas under the curve were >0.70, with sensitivity and specificity values ranging from 0.78 to 0.92. CONCLUSION This study provides absolute SCB and PASS iHOT-12 cutoff scores that can be used to define variations in 2-year (±2 months) outcomes in patients after hip arthroscopy for femoroacetabular impingement and chondrolabral pathology. iHOT-12 scores of 38, 60, and 86 were associated with abnormal, nearly normal, and normal reports of function respectively, with scores of 60, 71, and 86 associated with at least 50%, at least 75%, and 100% satisfaction after surgery, respectively.

Abstract
There is no information to define variations in hip arthroscopy outcomes at 2-year follow-up using the Hip Outcome Score (HOS). To offer a tiered system using HOS absolute substantial clinical benefit (SCB) and patient acceptable symptomatic state (PASS) scores for 2-year hip arthroscopy outcome assessment. This was a retrospective review of patients having hip arthroscopy for femoroacetabular impingement and/or chondrolabral pathology. On initial assessment and 2 years (±2 months) post-operatively, subjects completed the HOS activity of daily living (ADL) and Sports subscales, categorical self-rating of function and visual analog scale for satisfaction with surgery. Receiver operator characteristic analysis identified absolute SCB and PASS HOS ADL and Sports subscale scores. Subjects consisted of 462 (70%) females and 196 (30%) males with a mean age of 35.3 years [standard deviation (SD) 13] and mean follow-up of 722 days (SD 29). SCB and PASS scores for the HOS ADL and Sports subscales were accurate in identifying those at a ‘nearly normal’ and ‘normal’ self- report of function and at least 75% and 100% levels of satisfaction (area under the curve >0.70). This study provides tiered SCB and PASS HOS scores to define variations in 2-year (±2 months) outcome after hip arthroscopy. HOS ADL subscale scores of 84 and 94 and Sports subscale scores of 61 and 87 were associated with a ‘nearly normal’ and ‘normal’ self-report of function, respectively. HOS ADL subscale scores of 86 and 94 and Sports subscale score of 74 and 87 were associated with being at least 75% and 100% satisfied with surgery, respectively. Level of evidence: III, retrospective comparative study.

Abstract
Background Hip arthroscopy is a common surgical intervention for young and middle-aged adults with hip-related pain and dysfunction, who have high expectations for returning to physical activity following surgery. The purpose of this review was to evaluate the impact of hip arthroscopy on physical activity post-arthroscopy. Methods A systematic search of electronic databases was undertaken in identifying studies from January 1st 1990 to December 5th 2019. The search included English language articles reporting physical activity as an outcome following hip arthroscopy in adults aged 18-50 years. Quality assessment, data extraction and synthesis of included studies were undertaken. Results Full text articles (n = 234) were assessed for eligibility following screening of titles and abstracts (n = 2086), yielding 120 studies for inclusion. The majority (86%) of the studies were level 4 evidence. One study reported objective activity data. The most frequently occurring patient-reported outcome measure was the Hip Outcome Score-sport-specific subscale (HOS-SS, 84% of studies). Post--arthroscopy improvement was indicated by large effect sizes for patient-reported outcome measures (standard paired difference [95% confidence interval] −1.35[−1.61 to −1.09] at more than 2 years post-arthroscopy); however, the majority of outcome scores for the HOS-SS did not meet the defined level for a patient-acceptable symptom state. Conclusion The current level of available information regarding physical activity for post arthroscopy patients is limited in scope. Outcomes have focused on patients’ perceived difficulties with sport-related activities with a paucity of information on the type, quality and quantity of activity undertaken. Level of Evidence Level IV, systematic review of Level 2 through to Level 4 studies

Abstract
PURPOSE To determine when patients reach critical thresholds of clinical improvement after hip arthroscopy for femoroacetabular impingement (FAI) using previously defined cutoffs for the minimal clinically important difference (MCID) and patient acceptable symptomatic state (PASS) and to identify risk factors for prolonged recovery. METHODS Consecutive patients with a diagnosis of FAI who underwent unilateral hip arthroscopy between January 2010 and January 2015 with at least 2 years of clinical follow-up were studied. The modified Harris Hip Score was collected prospectively at 6 consecutive time points. The number of patients reaching the MCID and PASS at each time point was determined. RESULTS During the study period, 340 consecutive hip arthroscopies were performed in 316 patients with a mean final follow-up period of 50 months (range, 29-84 months). The mean modified Harris Hip Score and percentage of patients reaching the MCID and PASS increased at each time point. At 2 years, 271 patients (93%) surpassed the MCID and 212 patients (73%) achieved the PASS. Female sex, age of 40 years or older, and body mass index of 30 or greater were associated with lower rates of achieving the MCID and PASS at set time points. Patients undergoing labral repair had superior PASS rates at 3 months and beyond than patients undergoing labral debridement alone. Patients who did not achieve the PASS by 3 months were more likely to require reoperation. CONCLUSIONS Hip arthroscopy for FAI results in increased patient-reported outcome measures at interval follow-up. Most patients reach critical thresholds of minimal and satisfactory clinical improvement. Patients who are female, older, or obese or who undergo labral debridement alone are less likely to reach these milestones at major time intervals. Patients who do not reach the PASS by 3 months are more likely to require reoperation. LEVEL OF EVIDENCE Level IV, therapeutic case series.

Lall AC, Battaglia MR, Maldonado DR, Perets I, Laseter JR, Go CC, Domb BG. Does Femoral Retroversion Adversely Affect Outcomes After Hip Arthroscopy for Femoroacetabular Impingement Syndrome? A Midterm Analysis. Arthroscopy 2019; 35:3035-3046. [PMID: 31629582 DOI: 10.1016/j.arthro.2019.03.046] [Citation(s) in RCA: 22] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/13/2018] [Revised: 03/13/2019] [Accepted: 03/19/2019] [Indexed: 02/02/2023]
Abstract
PURPOSE To report 5-year outcomes of arthroscopic treatment of femoroacetabular impingement syndrome in patients with femoral retroversion compared with a control group of patients with normal femoral anteversion. METHODS Data were prospectively collected and retrospectively reviewed for all patients who underwent hip arthroscopy between August 2008 and April 2013. Patients were included in analysis if they underwent hip arthroscopy during this period and had femoral version ≤0° calculated using magnetic resonance imaging. Exclusion criteria included prior ipsilateral hip conditions/surgeries or Tönnis grade >1. These patients were pair matched with patients having femoral anteversion between 10° and 20° based on gender, body mass index ± 10, and age ± 10 years. Patient-reported outcomes (PROs) were collected at 3 months and 1 year postoperatively and annually thereafter. An a priori power analysis was performed. RESULTS A total of 59 patients were identified as the experimental group out of 69 eligible for inclusion (86%). All 59 patients were matched, with a mean age of 37.4 years and mean body mass index of 26.9. Twenty patients were female, and 39 were male. These patients demonstrated significant improvement from their preoperative state in all patient-reported outcomes and visual analog score scores (P < .001). Thirty-eight patients met the threshold for minimal clinically important difference, and 35 achieved patient acceptable symptomatic state for the modified Harris Hip Score questionnaire. Seven patients converted to total hip replacement. No differences were noted between retroverted and control patients in any of the outcome measures collected, in pain or satisfaction ratings, in the frequency of or duration to secondary surgeries or in complication rate (P > .05). CONCLUSIONS Patients with femoral retroversion demonstrated significantly higher outcomes at minimum 5-year follow-up after undergoing arthroscopic hip surgery. These outcomes were not different from those of patients with normal femoral version. While femoral retroversion should not be considered a contraindication to hip arthroscopy, it should be carefully considered as a factor in patient selection and surgical planning. LEVEL OF EVIDENCE Level III, retrospective comparative study.

[PMID: 30964540 DOI: 10.3928/01477447-20190403-01] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/30/2018] [Accepted: 10/10/2018] [Indexed: 02/03/2023]
Abstract
The purpose of this study was to determine the (1) return-to-sport rate for National Football League (NFL) players following femoroacetabular impingement surgery, (2) postoperative career length and games per season, (3) pre- and postoperative performance, and (4) postoperative performance compared with control players matched by position, age, years of experience, and performance. National Football League athletes who underwent hip arthroscopy for femoroacetabular impingement and matched controls were identified. A Bonferroni correction was used to control for multiple comparisons, with statistical significance set at P≤.007. Fifty-five players (63 surgeries) were analyzed (mean age, 27.5±3.4 years; mean years in NFL at time of surgery, 4.7±2.9). Forty-seven (53 surgeries, 84.1%) NFL players returned to sport at a mean of 6.7±3.8 months following surgery. There was no difference (P>.007) in the mean career length of players in the control group (3.7±2.2 years) vs players who underwent hip arthroscopy (3.5±2.1 years). There was no difference (P>.007) in mean games played per season of players in the control group (12.5±3.1) vs those who underwent hip arthroscopy (12.1±4.0). Quarterbacks had significantly better postoperative performance scores when compared with post-index matched controls (P=.007). The return-to-sport rate is high for NFL athletes after hip arthroscopy for femoroacetabular impingement. There were similar games per season and career lengths postoperatively compared with preoperatively and matched controls. Quarterbacks had significantly better postoperative performance when compared with matched controls. All other positions had similar postoperative performance compared with preoperatively and matched controls. [Orthopedics. 2019; 42(5):e423-e429.].

Performance and Return to Sport After Hip Arthroscopy for Femoroacetabular Impingement in Professional Athletes Differs Between Sports. Arthroscopy 2019; 35:1422-1428. [PMID: 30979626 DOI: 10.1016/j.arthro.2018.10.153] [Citation(s) in RCA: 34] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/17/2018] [Revised: 10/18/2018] [Accepted: 10/27/2018] [Indexed: 02/02/2023]
Abstract
PURPOSE To determine (1) return-to-sport rates for National Football League, Major League Baseball, National Basketball Association, and National Hockey League (NHL) athletes after hip arthroscopy for femoroacetabular impingement syndrome, (2) postoperative return-to-sport rate differences between sports, (3) differences in postoperative career length and games per season, (4) differences in preoperative and postoperative performance, and (5) postoperative performance compared with that of matched control players. METHODS Professional athletes who underwent hip arthroscopy for femoroacetabular impingement syndrome were identified. Matched control players were identified by position, age, experience, and performance. Return to sport was defined as playing in at least 1 game after surgery. Continuous variables for each group were compared by using a 2-tailed paired-samples Student t test or χ2 test. A Bonferroni correction was used to control for multiple comparisons with statistical significance defined by a P value < .002. RESULTS One hundred seventy-two players (86.4%) (mean age, 28.8 ± 5.2 years) were able to return to sport at an average of 7.1 ± 4.1 months. Athletes played 3.5 ± 2.4 years after surgery without significant differences between sports (P > .002). NHL players who underwent surgery played significantly fewer years (4.4 vs 3.3 years) (P < .001) and fewer games per season (4 fewer games) (P <.001) after surgery compared with control players. NHL players also had a significant decrease in performance after surgery compared with their performance before surgery (P < .001). In National Football League, Major League Baseball, and National Basketball Association athletes, no significant differences were found in games per season, career length, or preoperative performance compared with postoperative performance and performance of matched control players (P > .002). CONCLUSION The RTS rate for professional athletes after surgery for femoroacetabular impingement syndrome is high. Only NHL athletes had significantly shorter careers and played significantly fewer games per season compared with matched control players, with no difference between sports. NHL athletes had significantly worse postoperative performance compared with preoperative performance, with all other sports demonstrating a career-related decline similar to that of matched control players.

[PMID: 30647923 PMCID: PMC6328755 DOI: 10.1093/jhps/hny047] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/23/2018] [Revised: 08/23/2018] [Accepted: 10/20/2018] [Indexed: 11/15/2022] Open
Abstract
The purpose of this study was to determine if patients undergoing hip arthroscopy for labral pathology with contralateral total hip arthroplasty (THA) have a difference in revision surgeries or patient-reported outcomes (PROs) when compared with those patients undergoing hip arthroscopy for labral pathology with a native contralateral hip. A retrospective review was performed for patients that were undergoing hip arthroscopy between 2008 and 2015. Patients were included in the study group if they met the following inclusion criteria: Tönnis Grade 0 or 1, hip labral pathology, previous contralateral THA, and greater than 2-year follow-up with completion of all PROs or conversion to a THA. Exclusion criteria included the previous surgical history on ipsilateral hip, peritrochanteric or deep gluteal space arthroscopy performed concomitantly, or dysplasia [Lateral Center Edge Angle (LCEA) < 20°]. A 3:1 matched-pair study was conducted. Multiple PRO scores were recorded for both groups. There was no statistically significant difference in the modified Harris hip score, non-arthritic hip score, hip outcome score-sports specific sub-scale, visual analog pain score and patient satisfaction scores between both groups. However, the study group was noted to have six patients converted to THA (67%) at an average of 30 months post-operatively, compared with only four patients (15%) in the control group (P = 0.006). Hip arthroscopy cannot be currently recommended in patients who have undergone contralateral THA due to the high conversion to THA (67%).

Abstract
Background: Mental health impairments have been shown to negatively affect preoperative self-reported function in patients with various musculoskeletal disorders, including those with femoroacetabular impingement. Hypothesis: Those with symptoms of depression will have lower self-reported function, more pain, and less satisfaction on initial assessment and at 2-year follow-up than those without symptoms of depression. Study Design: Cohort study; Level of evidence, 3. Methods: Patients who were enrolled in a multicenter hip arthroscopic surgery registry and had 2-year outcome data available were included in the study. Patients completed the 12-item International Hip Outcome Tool (iHOT-12), visual analog scale (VAS) for pain, and 12-item Short-Form Health Survey (SF-12) when consenting for surgery. At 2-year follow-up, patients were emailed the iHOT, the VAS, and a rating scale of surgical satisfaction. Initial SF-12 mental component summary (MCS) scores <46.5 and ≤36 were used to qualify symptoms of depression and severe depression, respectively, as previously described and validated. Repeated-measures analysis of variance was performed to compare preoperative and 2-year postoperative iHOT-12, VAS, and satisfaction scores between those with and without symptoms of depression. Results: A total of 781 patients achieved the approximate 2-year milestone (mean follow-up, 735 ± 68 days), with 651 (83%) having 2-year outcome data available. There were 434 (67%) female and 217 (33%) male patients, with a mean age of 35.8 ± 13.0 years and a mean body mass index of 25.4 ± 8.8 kg/m2. The most common procedures were femoroplasty (83%), followed by synovectomy (80%), labral repair (76%), acetabuloplasty (58%), acetabular chondroplasty (56%), femoral chondroplasty (23%), and labral reconstruction (19%). The mean initial SF-12 MCS score was 51.5 ± 10.3, with cutoff scores indicating symptoms of depression and severe depression in 181 (28%) and 71 (11%) patients, respectively. Patients with symptoms of depression scored significantly (P < .05) lower on the initial iHOT-12 and VAS and 2-year follow-up iHOT-12, VAS, and rating scale of surgical satisfaction. Conclusion: A large number of patients who underwent hip arthroscopic surgery presented with symptoms of depression, which negatively affected self-reported function, pain levels, and satisfaction on initial assessment and at 2-year follow-up. Surgeons who perform hip arthroscopic surgery may need to identify the symptoms of depression and be aware of the impact that depression can have on surgical outcomes.

Abstract
PURPOSE To report minimum 5-year outcomes and risk factors for conversion to total hip arthroplasty (THA) in patients ≥50 years old undergoing hip arthroscopy to treat labral tears and femoroacetabular impingement (FAI). METHODS Data were prospectively collected on patients who underwent hip arthroscopy to treat labral tears and FAI between February 2008 and January 2012. The inclusion criteria were ≥50 years old at surgery, arthroscopic treatment for both labral tears and FAI, and preoperative patient-reported outcome (PRO) scores for modified Harris Hip Score (mHHS), Nonarthritic Hip Score (NAHS), Hip Outcome Score-Sports Specific Subscale (HOS-SSS), and Visual Analog Scale (VAS). The exclusion criteria were Tönnis grade > 1 and previous hip conditions or surgeries. RESULTS Of 103 eligible cases, 94 hips (91.3%) had minimum 5-year follow-up at a mean of 70.1 months (range, 60.0-95.1 months). All PROs and VASs demonstrated significant improvement at latest follow-up (P = .0001). Mean patient satisfaction was 8.4. All mean scores demonstrated durability from 2 years to latest follow-up, and NAHS (P = .009), HOS-SSS (P = .02), and VAS (P = .04) continued to significantly improve. Fifty-one (54.3%) of cases reached patient acceptable symptomatic state for mHHS, and 49 cases (52.1%) achieved minimal clinically important difference for this outcome measure. Four cases (4.3%) required secondary arthroscopy, and survivorship was 72.3%. Compared with survivors, the subgroup requiring THA demonstrated higher body mass indexes (P = .01), had larger alpha angles (P = .0200) and smaller lateral center-edge angles (P = .0200), and had higher proportions of Tönnis grade 1 (P = .0012), acetabular Outerbridge grade ≥ 2 (P = .0500), and femoral head Outerbridge grade ≥2 (P = .0001). CONCLUSIONS Hip arthroscopy for the treatment of labral tears and FAI in patients ≥50 years old demonstrates statistically significant PRO improvements at minimum 5-year follow-up. However, due to potential for subsequent need for THA in a subset of this population, surgeons should use rigorous selection criteria and counsel patients appropriately.

Abstract
The purpose of this study was to report the proportion of venous thromboembolic events (VTE) in patients undergoing primary hip arthroscopy for femoroacetabular impingement (FAI) and present a critical overview of the literature to aid in better result interpretation. MedLine, Scopus and Web of Science databases were searched from January 2000 to March 2017. Four thousand-five-hundred and seventy-seven hip cases were included in the meta-analysis of 38 studies. The mean age of patients was 36 ± 1.8 years and the mean follow-up time was 20.6 months. The meta-analysed rate of deep vein thrombosis (DVT) in patients undergoing primary hip arthroscopy for FAI syndrome was 1.18%; 95%CI [0.8–1.74%]; The meta-analysed rate of pulmonary embolism (PE) in patients undergoing primary hip arthroscopy for FAI syndrome was 0.59%; 95%CI [0.38–0.92%]. Quality assessment was performed using the Methodological Index for Non-Randomized Studies (MINORS) criteria the Quality in Prognostic Studies (QUIPS) tool. Sensitivity analysis was conducted to assess for publication bias and its influence on the results. The corrected for publication bias proportion of DVT was 2.02%; 95%CI [1.36–2.99%]. The DVT rate was double following the correction of bias while additional types of bias were detected. Attention must be paid when considering the outcomes of observational studies to make clinical decisions. Insufficient evidence exists to support whether anti-VTE chemoprophylaxis should be administered to patients undergoing primary hip arthroscopy for FAI. Due to the life-threatening character of this complication, the results should serve as starting point to design clinical trials and establish guidelines. Until then, the application of preventive measures against VTE should be decided on a case-by-case basis.

Abstract
BACKGROUND Obesity is a negative prognostic factor for various surgical procedures. The purpose of this study was to compare patients with obesity who underwent hip arthroscopy for femoroacetabular impingement and labral tears with a match-controlled group of normal-weight patients. METHODS Data were prospectively collected and retrospectively reviewed for patients who underwent arthroscopy between February 2008 and December 2011. Inclusion criteria were treatment for femoroacetabular impingement and labral tears and completed preoperative patient-reported outcomes and visual analog scale (VAS) for pain. Exclusion criteria were previous ipsilateral hip conditions or preoperative Tönnis grade of ≥2. Patients with obesity (body mass index [BMI] of ≥30 kg/m) were matched and were compared with normal-weight patients (BMI of 18.5 to 24.99 kg/m) using a 1:1 ratio by age at the time of the surgical procedure within 5 years, sex, acetabular Outerbridge grade (0 or 1 compared with 2, 3, or 4), and capsular treatment. RESULTS Of the 96 obesity cases with follow-up, 74 were pair-matched to control cases. The mean BMI was 34.3 kg/m for the obesity group and 22.7 kg/m for the control group (p < 0.0001). The mean follow-up time was 71.6 months for the obesity group and 71.3 months for the control group (p = 0.41). All mean preoperative patient-reported outcomes and VAS scores for patients without conversion to total hip arthroplasty were significantly worse in the obesity group: modified Harris hip score (p = 0.0001), Non-Arthritic Hip Score (p = 0.0001), Hip Outcome Score Sports-Specific Scale (HOS-SSS) (p = 0.015), and VAS (p = 0.01). No significant differences were observed with regard to demographic characteristics, intraoperative findings, procedures, follow-up scores, magnitudes of improvement, or secondary arthroscopy rates (p > 0.05). Both groups demonstrated significant improvements in mean outcome scores at ≥5 years (p < 0.0001). In both groups, no significant differences were detected in mean outcome scores between 2 years and ≥5 years (p > 0.05). The conversion rate to total hip arthroplasty was 29.7% for the obesity group and 14.9% for the control group (relative risk, 2.0 [95% confidence interval, 1.1 to 3.8]; p = 0.04). CONCLUSIONS Hip arthroscopy for the treatment of femoroacetabular impingement and labral tears in patients with obesity yielded significant improvements at ≥5 years; these results were similar to a matched group of normal-weight patients. However, patients with obesity demonstrated a twofold increased risk of conversion to total hip arthroplasty. LEVEL OF EVIDENCE Prognostic Level III.

Abstract
BACKGROUND Hip arthroscopy is a minimally invasive surgical technique increasingly being used to treat hip pathology. There is evidence that a proportion of patients require total hip arthroplasty in the years immediately following arthroscopy, suggesting that these patients have derived only a limited benefit from the procedure. Identification of risk factors for early progression to hip arthroplasty may enable refinement of hip arthroscopy indications and more informed decision making. The aim of this study is to identify the proportion of patients in a hip arthroscopy cohort who progress to total hip arthroplasty within 2 years of arthroscopy, and to analyse risk factors for this early progression. METHODS A retrospective cohort analysis was conducted on all patients who underwent hip arthroscopy at one tertiary institution from 2004 to 2013. Hospital data were linked to the Australian Orthopaedic Association National Joint Replacement Registry in 2016 to identify subsequent hip arthroplasty. RESULTS There were 989 arthroscopies performed on 947 patients; 447 were female (48.1%), the mean age was 41.1 years (SD: 14.23) and osteoarthritis was present at arthroscopy in 31.5%. Total hip arthroplasty occurred in 129 patients (13%) within 2 years. Multivariable logistic regression revealed osteoarthritis, age >50 years and previous arthroscopy were significant risk factors for arthroplasty within 2 years (adjusted odds ratios (confidence intervals): 4.6 (2.91-7.16), 3.8 (2.44-5.87), 2.5 (1.16-5.81)). CONCLUSIONS Osteoarthritis, older age and history of arthroscopy were independent risk factors for early progression to arthroplasty; these factors should be considered within clinical decision-making, and when discussing potential arthroscopy outcomes with patients.

Abstract
The use of hip arthroscopy continues to expand. Understanding potential pitfalls and complications associated with hip arthroscopy is paramount to optimizing clinical outcomes and minimizing unfavorable results. Potential pitfalls and complications are associated with preoperative factors such as patient selection, intraoperative factors such as iatrogenic damage, traction-related complications, inadequate correction of deformity, and nerve injury, or postoperative factors such as poor rehabilitation. This article outlines common factors that contribute to less-than-favorable outcomes.

Arthroscopy 2018; 34:1319-1328.e9. [PMID: 29402587 DOI: 10.1016/j.arthro.2017.11.037] [Citation(s) in RCA: 22] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/07/2017] [Revised: 11/28/2017] [Accepted: 11/29/2017] [Indexed: 02/02/2023]
Abstract
PURPOSE The purposes of this review were (1) to collate and synthesize research studies reporting any outcome measure on both open and arthroscopic surgical treatment of femoroacetabular impingement (FAI) syndrome and (2) to report the prevalence and consistency of outcomes across the included studies. METHODS A computer-assisted literature search of the MEDLINE, CINAHL (Cumulative Index to Nursing and Allied Health Literature), and Embase databases was conducted using keywords related to FAI syndrome and both open and arthroscopic surgical outcomes, resulting in 2,614 studies, with 163 studies involving 14,824 subjects meeting the inclusion criteria. Two authors independently reviewed study inclusion and data extraction with independent verification. The prevalence of reported outcomes was calculated and verified by separate authors. RESULTS Between 2004 and 2016, there has been a 2,600% increase in the publication of surgical outcome studies. Patients had a mean duration of symptoms of 27.7 ± 21.5 months before surgery. Arthroscopy was the surgical treatment used in 71% of studies. The mean final follow-up period after surgery was 32.2 ± 17.3 months. Follow-up time frames were reported in 78% of studies. Ten different patient-reported outcome measures were reported. The alpha angle was reported to be measured 42% less frequently as a surgical outcome than as a surgical indication. Surgical complications were addressed in only 53% of studies and failures in 69%. Labral pathology (91% of studies reporting) and chondral pathology (61%) were the primary coexisting pathologies reported. Clinical signs, as defined by the Warwick Agreement on FAI syndrome, were reported in fewer than 25% of studies. CONCLUSIONS Most FAI syndrome patients have longstanding pain and potential coexisting pathology. Patient-reported outcome measures and diagnostic imaging are the most frequently reported outcomes. Measures of hip strength and range of motion are under-reported. It is unclear whether the inconsistency in reporting is because of lack of measurement or lack of reporting of specific outcomes in these studies. Current surgical outcomes are limited to mid-term surgical follow-up time frames and inconsistent outcome reporting. LEVEL OF EVIDENCE Level IV, systematic review of Level I through IV studies.

Abstract
BACKGROUND There has been increasing interest in defining clinically meaningful outcomes in patient reported outcomes following orthopaedic surgery. Little is known about the factors associated with clinically meaningful outcomes after hip arthroscopy for femoroacetabular impingement. STUDY DESIGN Case-control study; Level of evidence, 3. PURPOSE To report on a large, prospectively collected consecutive series of patients who underwent comprehensive arthroscopic treatment of femoroacetabular impingement (FAI) and capsular management with greater than 2-year follow-up. The objectives were to determine (1) what percentage of patients achieve clinically significant outcomes after hip arthroscopic surgery for FAI as determined by the minimal clinically important difference (MCID) and patient acceptable symptom state (PASS) and (2) what factors are associated with achieving the MCID and PASS. METHODS Data from an institutional repository of consecutive patients undergoing primary hip arthroscopic surgery with routine capsular closure for FAI that had failed nonsurgical management between January 2012 and January 2014 were prospectively collected and analyzed. Of 474 patients during the enrollment period, 386 (81.4%) patients were available for a minimum 2-year follow-up. Demographics, radiographic measurements, intraoperative characteristics, and patient-reported outcome scores were collected. The primary outcome measure was achieving published thresholds for the MCID and PASS for the Hip Outcome Score (HOS)-Activities of Daily Living (ADL) in patients with FAI. The HOS-Sport-Specific Subscale (SSS), complications, and reoperations were secondary outcome measures. Multivariate regression analyses were conducted to identify factors associated with achieving the MCID and PASS. RESULTS At a minimum of 2-year follow-up, the patients had statistically significant improvements in all patient-reported outcomes (HOS-ADL, HOS-SSS, and modified Harris Hip Score [mHHS]; P < .001 for all), with a 1.2% rate of revision hip arthroscopic surgery and 1.7% rate of conversion to total hip arthroplasty. The MCID was achieved by 78.8% of patients for the HOS-ADL, and the PASS was achieved by 62.5% for the HOS-ADL. Younger age ( P = .008), Tönnis grade 0 ( P = .022), and lower preoperative HOS-ADL score ( P < .001) were associated with successfully achieving the MCID for the HOS-ADL. Younger age ( P < .001), larger medial joint space width ( P = .028), and higher preoperative HOS-ADL score ( P < .001) were associated with achieving the PASS for the HOS-ADL. Younger age ( P < .001), lower body mass index ( P = .006), non-workers' compensation status ( P = .020), and lower preoperative HOS-SSS score ( P < .001) were associated with achieving the MCID for the HOS-SSS. Younger age ( P = .001), Tönnis grade 0 ( P = .014), running ( P = .008), and higher preoperative HOS-SSS score ( P < .001) were associated with achieving the PASS for the HOS-SSS. Overall, 49.4% of patients achieved all 4 clinically significant outcomes: both the MCID and PASS for the HOS-ADL and HOS-SSS. CONCLUSION The majority of patients undergoing hip arthroscopic surgery with routine capsular closure for FAI experienced clinically significant outcomes that met the MCID or PASS criteria, with low rates of revision and conversion to total hip arthroplasty. Factors associated with these successful outcomes on multivariate analyses included younger age with a normal joint space. Patients with lower preoperative HOS scores were more likely to achieve the MCID, whereas patients with higher preoperative HOS scores were more likely to achieve the PASS.

Abstract
The aim of this article is to examine the results of arthroscopic management of patients with labral pathology who have preoperative magnetic resonance images (MRIs) demonstrating subchondral cysts. This institution's database was searched for patients who underwent hip arthroscopy and had subchondral cysts on MRI and >2-year follow-up. Exclusion criteria included previous hip surgery, Tönnis grade >1, inflammatory arthritis, Perthes, slipped capital femoral epiphysis or abductor repair. Patient-reported outcome (PRO) scores including visual analog scale, modified Harris hip score (mHHS), non-arthritic hip score and hip outcome score sports-specific subscale (HOS-SSS) were gathered preoperatively, at 3 months, and annually thereafter. The change in PRO scores was compared with the minimally clinical important difference (MCID) to quantify improvement. Sixty-nine patients were eligible for this study, of which 65 (94%) had >2-year follow-up. All PROs were significantly improved at latest follow-up (P < 0.001). Mean patient satisfaction was 7.2. There was no correlation between Outerbridge grade III or IV cartilage damage noted during arthroscopy and subchondral femoral and acetabular cysts noted on MRI. Seventeen patients required reoperation [13 total hip arthroplasty (THAs) and 4 revision arthroscopies]. Patients with femoral subchondral cysts converted to THA 36% of the time. MCIDs for mHHS and HOS-SSS were surpassed by 63% and 68% of patients, respectively. Hip arthroscopies performed on patients with subchondral cysts present on preoperative MRI should be approached with caution. The rate of conversion to hip arthroplasty appears to be higher than that reported in the literature for patients who undergo arthroscopy without preoperative subchondral cysts. For patients who did not require hip arthroplasty or revision arthroscopy, patients demonstrated significant improvement in symptoms compared with the preoperative state.

Abstract
Background: Femoral retroversion has been noted as a possible risk factor for poor clinical results after hip arthroscopic surgery. Purpose: To compare the outcomes of the arthroscopic treatment of hip abnormalities in patients with femoral retroversion to patients with femoral anteversion between 10° and 20°. Study Design: Cohort study; Level of evidence, 3. Methods: Between November 2011 and September 2013, 790 hip arthroscopic procedures were performed at a single institution. Of these, 59 hips (7.5%) were located in patients with femoral version ≤0°, calculated using preoperative magnetic resonance imaging. These patients were pair matched, based on body mass index ±5 kg/m2, age ±5 years, and Tönnis grade, with 59 patients with femoral anteversion between 10° and 20°. Exclusion criteria included Perthes disease, inflammatory arthritis, slipped capital femoral epiphysis, previous hip surgery, abductor repair, lateral center-edge angle <20°, Tönnis grade >1, and acetabular profunda or protrusio. Patient-reported outcomes (PROs) were recorded preoperatively, at 3 months postoperatively, and annually thereafter. The PROs utilized were the modified Harris Hip Score (mHHS), Non-Arthritic Hip Score (NAHS), and Hip Outcome Score–Sports-Specific Subscale (HOS-SSS). The visual analog scale (VAS) was collected to assess the patients’ pain; patient satisfaction scores (0-10) were also collected. Radiographs were collected at the above time intervals as well. Results: Two patients from the control group and 1 patient from the retroverted group required total hip arthroplasty at a mean 19.5 and 26.3 months, respectively. Both groups demonstrated significant improvement from their preoperative state in all PRO and VAS scores (P < .001). No differences in preoperative, postoperative, or change in PRO and VAS scores between the groups were noted. Conclusion: Patients with femoral retroversion reported similar outcomes compared to patients with normal femoral version when undergoing hip arthroscopic surgery. Both groups had similar improvements from the preoperative state.

Abstract
PURPOSE To determine if (1) absorbed radiation dose and (2) fluoroscopy time decreased with experience over the first 100 cases of a single surgeon's hip arthroscopy practice. METHODS Subjects who underwent hip arthroscopy for symptomatic femoroacetabular impingement and labral injury were eligible for analysis. Inclusion criteria included the first 100 subjects who underwent hip arthroscopy by a single surgeon (December 2013 to December 2014). Subject demographics, procedure details, fluoroscopy absorbed dose (milligray [mGy]), and time were recorded. Subjects were categorized by date of surgery to one of 4 possible groups (25 per group). One-way analysis of variance was used to determine if a significant difference in dose (mGy) or time was present between groups. Simple linear regression analysis was performed to determine the relation between case number and both radiation dose and fluoroscopy time. RESULTS Subjects underwent labral repair (n = 93), cam osteoplasty (n = 90), and pincer acetabuloplasty (n = 65). There was a significant (P < .001 for both) linear regression between case number and both radiation dose and fluoroscopy time. A significant difference in mGy was observed between groups, group 1 the highest and group 4 the lowest amounts of radiation (P = .003). Comparing individual groups, group 4 was found to have a significantly lower amount of radiation than group 1 (P = .002), though it was not significantly lower than that of group 2 (P = .09) or group 3 (P = .08). A significant difference in fluoroscopy time was observed between groups, group 1 the highest and group 4 the lowest times (P = .05). Comparing individual groups, group 4 was found to have a significantly lower fluoroscopy time than group 1 (P = .039). Correction for weight, height, and body mass index all revealed the same findings: significant (P < .05) differences in both dose and time across groups. CONCLUSIONS The absorbed dose of radiation and fluoroscopy time decreased significantly over the first 100 cases of a single surgeon's hip arthroscopy practice learning curve. LEVEL OF EVIDENCE Level IV, therapeutic, retrospective, noncomparative case series.

Abstract
BACKGROUND It remains unknown how variations in body mass index (BMI) influence outcomes after primary hip arthroscopic surgery with capsular plication for femoroacetabular impingement (FAI). PURPOSE To evaluate the effect that abnormal BMI (namely, overweight, obese, morbidly obese, and underweight) versus normal weight has on patient-reported clinical outcomes more than 2 years postoperatively from primary hip arthroscopic surgery with capsular plication by a single surgeon. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS A clinical repository containing patients undergoing primary hip arthroscopic surgery for FAI between January 1, 2012, and January 1, 2014, with a minimum 2-year follow-up was queried. Outcome measures included the Hip Outcome Score (HOS)-Activities of Daily Living (ADL), HOS-Sports, modified Harris Hip Score (mHHS), visual analog scale (VAS) for pain; satisfaction, and Patient Acceptable Symptomatic State (PASS) for the HOS-ADL; scores were collected preoperatively and at 3 months, 1 year, and minimum 2 years postoperatively. Included patients were segregated by preoperative BMI into the following categories: underweight (<18.5 kg/m2), normal (18.5-24.9 kg/m2), overweight (25.0-29.9 kg/m2), obese (30.0-34.9 kg/m2), and morbidly obese (≥35.0 kg/m2). A multivariate logistic regression model controlling for patient demographics and disease severity was used to identify independent associations between BMI categories and outcomes. A Bonferroni adjustment lowered the threshold for significance to P < .01. RESULTS There were 409 hips in 381 patients appropriate for study inclusion: 7 underweight, 197 normal BMI, 130 overweight, 31 obese, and 16 morbidly obese. The mean age was 33.1 ± 12.1 years, with 232 (61%) female patients. At 2 years postoperatively, significant differences in the trend among HOS-ADL, HOS-Sports, and mHHS scores were evident, with normal BMI patients, followed by underweight patients, demonstrating greater scores than their overweight, obese, and morbidly obese counterparts. Obese patients demonstrated lower satisfaction scores than normal BMI patients. Overweight, obese, and morbidly obese patients had lower improvements in VAS pain scores compared with normal BMI patients. Increasing BMI (not subdivided into the 5 BMI categories) was associated with a higher infection risk (mean BMI for infections: 32.3 ± 9.8 kg/m2 vs mean BMI for noninfections: 25.2 ± 4.8 kg/m2; P = .0035). However, with multivariate analysis, no significant differences in patient clinical outcomes between the BMI categories met the threshold for significance. Among obese patients (BMI ≥30.0 kg/m2), no specific risk factors were found to be significantly associated with decreases in the change in VAS, HOS-ADL, HOS-Sports, mHHS, satisfaction, or PASS for the HOS-ADL scores. However, because of the small cohort sizes at the extremes of the BMI categories, this analysis may have been underpowered to identify a significant difference in underweight or morbidly obese patients. CONCLUSION In the current cohort, there were multiple potential confounding variables, and while some clinical differences were observed initially (higher HOS-ADL, HOS-Sports, and mHHS scores for normal BMI patients than overweight and obese patients at 2 years postoperatively; lower satisfaction scores for obese patients than normal BMI patients; and lower improvement in VAS pain scores for overweight, obese, and morbidly obese patients when compared with normal BMI patients), after multivariate analysis, no associations were observed between BMI and clinical outcomes after hip arthroscopic surgery with capsular plication for FAI.

Abstract
The role and function of the acetabular labrum have been studied extensively in the past decade. Recent studies have proposed that, in addition to causing pain and mechanical symptoms, labral tears may accelerate arthritis. Labral preservation is believed to be important because of the role the labrum plays in maintaining a healthy joint. Treatment of the acetabular labrum is becoming one of the fastest growing fields in orthopaedics; therefore, the treatment decision-making process must be refined. Currently, three commonly practiced labral treatments are available: repair, débridement, and reconstruction. Arguments for and against each treatment option exist in the literature. Reviewing the currently proposed indicators for labral tear treatments in conjunction with the treatment procedures yields a thorough decision-making guide for choosing the appropriate labral procedure.

Abstract
PURPOSE To (1) report clinical outcomes, complication rates, and total hip arthroplasty (THA) conversion rates for patients age 40 or older who underwent hip arthroscopy, and (2) report any age-related predictors of outcome identified in the literature. METHODS MEDLINE, EMBASE, and PubMed were searched for relevant studies and pertinent data were abstracted from eligible studies. No meta-analysis was performed because of heterogeneity amongst studies. RESULTS Seventeen studies were included in this review comprising 16,327 patients, including 9,954 patients age 40 or older. All studies reported statistically significant improvements in outcomes after hip arthroscopy for femoral osteochondroplasty, labral repair, or unspecified indications. In patients 40 or older who underwent labral debridement, these improvements were not clinically significant. Obesity and osteoarthritic changes predicted poorer outcomes. Only 1 of 3 studies directly comparing the 2 groups found that patients 40 or older had a significantly less improvement in a standardized hip outcome score than patients under 40 after hip arthroscopy, but all found that patients 40 or older had significantly higher rates of THA conversion. The rate of conversion to THA was 18.1% for patients 40 or older, 23.1% for patients over 50, and 25.2% for patients over 60 with a mean of 25.0 months to THA. CONCLUSIONS Indications for hip arthroscopy including femoral osteochondroplasty and labral repair resulted in clinically significant improvements in patients 40 or older in most research studies examined in this review, whereas labral debridement did not produce clinically significant improvements postoperatively in the same studies. In these studies, the rate of conversion to THA is higher than in patients under 40 and increases with each decade of life, with many individual studies showing a significant increase in the rate of THA conversion. Hip arthroscopy may be suitable for some patients 40 or older, but patient selection is key and patients should be informed of the higher risk of conversion to THA.

Abstract
Obesity represents a unique challenge in orthopaedic surgery, the impact of which is seen through all phases of injury: in the development of disease, during the operative procedure, and throughout the rehabilitation period. Given the high prevalence of obesity in the United States and around the world, this patient population represents a substantial proportion of patients in need of orthopedic care. The effects of this disease constrain both medical and financial resources. For obese patients undergoing orthopedic procedures, adequate steps must be taken to minimize the risks that occur before, during, and after surgical intervention. This literature review discusses the impact of obesity on arthroscopic procedures, with a focus on procedures involving the shoulder, hip, and knee. The management of obese patients during the perioperative period should address the specific concerns relating to these patients. Obesity is a risk factor for numerous comorbidities, is associated with surgical complications, and is a predictor of poor functional outcomes following arthroscopy. Efforts to minimize the negative impact of obesity on arthroscopic procedures are crucial.

Abstract
PURPOSE The purpose of this study was to evaluate how patient satisfaction after surgical femoroacetabular impingement (FAI) treatment is measured and reported in the current evidence base. METHODS A review of the MEDLINE database was performed. Clinical outcome studies of FAI that reported a measure of patient satisfaction were included. Patient demographics, clinical outcome scores, and patient satisfaction measures were extracted. The NewCastle Ottawa Scale (NOS) was used to grade quality. Statistical analysis was primarily descriptive. RESULTS Twenty-six studies met inclusion criteria; the mean NOS score among included studies was 5.7. Most studies were level 3 or 4 (n = 25, 96.1%). A 0 to 10 numeric scale, described by some studies as a visual analog scale, was the most commonly used method to assess satisfaction (n = 21; 80.8%), and mean reported scores ranged from 6.8 to 9.2 out of 10. Four studies (15.4%) used an ordinal scale, and 1 study (3.8%) used willingness to undergo surgery again as the measure of satisfaction. None of the included studies assessed preoperative satisfaction or patient expectation. Pooled cohort analysis was limited by significant overlapping study populations. Predictors of patients' satisfaction identified in included studies were presence of arthritis and postoperative outcome scores. CONCLUSIONS Patient satisfaction was not uniformly assessed in the literature. Most studies used a 0- to 10-point satisfaction scale, but none distinguished between the process of care and the outcome of care. Although satisfaction scores were generally high, the quality of the methodologies in the studies that reported satisfaction was low, and the studies likely included overlapping patient populations. More work needs to be done to develop standardized ways for assessing patient satisfaction after arthroscopic hip surgery and other procedures in orthopaedic sports medicine.

Abstract
Although most patients have successful outcomes after hip arthroscopy, a minority of patients experience complications that may impact their recovery and long-term benefit. As most of these complications can be minimized by appropriate surgical technique, many tips have been recommended. Additionally, the reasons behind clinical failure postoperatively have been scrutinized, which include, most commonly, incomplete correction of osseous pathomorphology, underappreciated preexisting hip osteoarthritis, and/or an incorrect preoperative diagnosis. Meticulous preoperative planning, evaluation of advanced imaging studies, and proper patient selection will help to reduce the number of postoperative failures and increase the chance of a successful outcome following hip arthroscopy.

Abstract
BACKGROUND Obesity is a known risk factor for the development of adult acquired flatfoot deformity (AAFD), but obesity's effects on outcomes following AAFD reconstruction are unknown. We hypothesized that obesity would negatively impact outcomes following joint-preserving stage II AAFD reconstruction. METHODS This retrospective study compared the outcomes of normal-weight (18.5 kg/m(2) ≤ BMI < 25 kg/m(2)), overweight (25 kg/m(2) ≤ BMI < 30 kg/m(2)), and obese (BMI ≥ 30 kg/m(2)) patients after AAFD reconstruction. Clinical outcome measures included the Foot and Ankle Outcome Score (FAOS), Short-Form 12 (SF-12), and Numeric Rating Scale of Pain (NRS Pain) administered preoperatively and at least 1 year postoperatively. Anteroposterior and lateral radiographs were taken preoperatively and at least 6 months postoperatively. Pre- to postoperative changes in outcome measures were assessed within BMI classes. Preoperative, postoperative, and pre- to postoperative changes in outcomes were compared among BMI classes. There were 41 normal-weight patients, 39 overweight patients, and 44 obese patients with a mean age of 56 years, FAOS follow-up of 2.9 years, and radiographic follow-up of 2.1 years. Demographics and reconstructive procedures were comparable among the 3 BMI classes. RESULTS All outcomes significantly increased pre- to postoperatively in the 3 groups with the exception of the FAOS Symptoms subscale for normal-weight patients (P = .340) and SF-12 Mental Component score for all 3 BMI classes (P > .999). Preoperatively, obese patients had more symptoms than normal-weight patients, scoring 12 points lower on the FAOS Symptoms subscore (P = .008). Obese patients also scored 11 points lower preoperatively on the SF-12 Overall score (P = .028) and had 31% greater pain than normal-weight patients (P = .003). There were no differences among the 3 BMI classes in any postoperative outcomes assessed. CONCLUSION Although obese patients had significantly worse symptoms, overall health, and NRS pain scores preoperatively, the short-term clinical and radiographic outcomes of stage II AAFD reconstruction were similar for normal-weight, overweight, and obese patients. We suggest that joint-preserving reconstruction remains a viable alternative to fusion of the triple joint complex for the treatment of overweight and obese stage II AAFD patients.

Abstract
Discussion persists about the outcome and results of hip arthroscopy in obese patients. Hip arthroscopy gained popularity over time. A current discussion is if obese patients can reach similar results after surgery compared with non-obese. To our knowledge, this is the first systematic review of literature about hip arthroscopy and obesity. We searched the Pubmed/Medline databases for literature and included three studies that compared the outcome of hip arthroscopy between different BMI groups. We extracted and pooled the data. For continues data a weighted mean difference was calculated, for dichotomous variables a weighted odds ratio (OR) was calculated using Review Software Manager. Heterogeneity of the included studies was calculated using I2 statistics. Data were extracted from two studies. In the Obese group, there was significant more conversion to total hip replacement or resurfacing hip replacement (OR = 2.21, 95% CI 1.07–4.56) and more re-arthroscopy (OR = 4.68, 95% CI 1.41–15.45). Any reoperation occurred more often in the obese group (OR = 2.87, 95% CI 1.53–5.38). In the Non Arthritic Hip Score obese scored lower than the non-Obese group [10.9 (−14,6 to 7.1)]. For the modified Harris Hip Score the score is − 6,6, according to the MCID this difference is clinically relevant. For both scores obese show lower outcomes but similar improvement after hip arthroscopy. Regarding a higher chance of needing a re-operation and lower subjective outcome scores obesity appears to have a negative influence on the outcome of hip arthroscopy.
