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.

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

Background: Hip arthroscopy has been shown to be effective in athletes who have femoral acetabular impingement and labral tearing. The effect of complete capsular closure versus nonclosure on return to play is unknown. Hypothesis: Complete capsular closure after hip arthroscopy would lead to a higher rate and faster return to sports in high-level athletes. Study Design: Cohort study; Level of evidence, 3. Methods: A nonrandomized retrospective review was performed of high school, collegiate, and professional athletes undergoing hip arthroscopy by a single high-volume hip arthroscopic surgeon. Athletes were divided into those undergoing complete capsular closure (CC group) and non–capsular closure (NC group) after hip arthroscopy. Rate and time to return to play were determined between the 2 groups. Patient-reported outcomes including modified Harris Hip Score (mHHS), Hip Outcome Score Activities of Daily Living (HOS-ADL), and Hip Outcome Score Sport-Specific Subscale (HOS-SSS) were obtained at a minimum of 2 years. Results: A total of 111 athletes with a minimum 2-year follow-up were included in the study. There were 62 in the CC group and 49 in the NC group. A higher percentage of athletes in the CC group returned to play compared with that in the NC group (90.3% vs 75.5%, respectively; P = .03). The CC group returned to play at a mean ± SD of 4.7 ± 1.9 months compared with 5.8 ± 2.6 months in the NC group ( P < .001). Patients in the CC group met the minimal clinically important difference for the mHHS, HOS-ADL, and HOS-SSS patient-reported outcomes at higher percentages: mHHS, 98.3% vs 87.7% for CC vs NC, respectively ( P = .02); HOS-ADL, 98.3% vs 87.7% ( P = .02); and HOS-SSS, 96.7% vs 89.7% ( P = .13). The difference between groups was statistically significant for mHHS and HOS-ADL. Conclusion: Complete capsular closure after hip arthroscopy was associated with faster return to play and a higher rate of return compared with that of nonclosure of the capsule in this sample population of high-level athletes. At a minimum 2-year follow-up, complete capsular closure was associated with significantly higher patient-reported outcomes compared with those of nonclosure in athletes who underwent hip arthroscopy.

Background: Patients with pincer-type femoroacetabular impingement are commonly treated with arthroscopic reduction of acetabular depth as measured by the lateral center-edge angle (LCEA). The optimal amount of rim reduction has not been established, although large resections may increase contact pressures through the hip. A recent publication demonstrated inferior surgical outcomes in patients with acetabular overcoverage as compared with normal acetabular coverage. Casual observation of our database suggested equivalent improvements, prompting a similar analysis. Purpose: To analyze patient-reported outcomes after hip arthroscopy for femoroacetabular impingement in patients with acetabular overcoverage who were matched with controls with normal coverage, as well as to analyze associations with reduction in LCEA. Study Design: Cohort study; Level of evidence, 3. Methods: Data were collected prospectively from patients with a minimum 2-year follow-up after receiving hip arthroscopy for femoroacetabular impingement by a single surgeon. Cases were reviewed to identify those with pincer-type morphology (LCEA >40°) and matched according to sex, age, chondral damage, and surgery date in a 1:1 ratio with controls with an LCEA of 25° to 40°. The surgical goal was to reduce the LCEA to the upper end of the normal range with minimal rim resection, usually 35° to 37°. Radiographic measurements of coverage, intraoperative findings, procedures, and patient-reported outcomes were recorded, including the 12-Item International Hip Outcome Tool, Non-arthritic Hip Score, Hip Disability and Osteoarthritis Outcome Score, visual analog scale for pain, rates of revision or reoperation, and conversion to total hip arthroplasty. Results: A total of 114 hips (93 patients) for the pincer group were matched 1:1 from 616 hips (541 patients) for the control group. The pincer group (mean ± SD age, 34.5 ± 12.2 years) did not differ in age, body mass index, or follow-up from controls. LCEA was reduced in both groups pre- to postoperatively: the pincer group from 44.0° ± 2.8° to 34.2° ± 3.5° and the controls from 32.9° ± 3.9° to 31.0° ± 3.0°. No differences in improvement were observed: iHOT-12 improved by 35.7 points in both groups ( P = .9 for analysis of variance interaction) and Nonarthritic Hip Score by 22.3 points ( P = .6). From all eligible surgical procedures, 2-year follow up rates were 2.5% and 2.6% for the pincer and control cohorts, respectively, and 1.2% and 0.3% for conversion to total hip arthroplasty. Conclusion: Arthroscopic management of acetabular overcoverage can achieve excellent results, equivalent to arthroscopy for other causes of symptomatic femoroacetabular impingement. A key finding was smaller rim resections producing a mean postoperative LCEA of 34.2° with a small standard deviation.

Objectives: To determine the rate of return to sport (RTS) in high-level athletes undergoing bilateral hip arthroscopy and report minimum 1-year patient-reported outcomes (PROs) for this cohort. We hypothesized that RTS rates, as well as sport-specific PROs, will be lower than the rates and scores previously reported in the literature for unilateral hip arthroscopy. Methods: Data were prospectively collected on all patients undergoing hip arthroscopy at our institution from November 2011 to July 2018. Patients were included if they underwent bilateral hip arthroscopy and were either a high school, collegiate, or professional athlete prior to their first surgery. RTS was defined as a patient’s return to competitive participation in their respective sport. Additional PROs, including modified Harris Hip Score (mHHS), nonarthritic hip score (NAHS), and Hip Outcome Score-Sports Specific Subscale (HOS-SSS), as well as complication rates and future surgeries were documented and compared for all patients. Results: A total of 87 patients met inclusion criteria, for which follow-up was available for 82 (94.3%). At latest follow-up, 44 (53.7%) patients returned to sport. Of patients returning, 56% did so at the same level or higher. The most common reasons for not returning to sport were due to graduation/lifestyle change (47.4%) and hip symptoms (44.7%). Patients returning to sport had significantly higher PROs at latest follow-up relative to those who did not return, including for mHHS (93.7 vs. 87.5), NAHS (94.4 vs. 88.2), HOS-SSS (90.9 vs. 78.2) (P < 0.05). Rates of achieving PASS and MCID for mHHS were not significantly different. However, for HOS-SSS, patients who returned had significantly higher rates of achieving the MCID and PASS. Conclusion: Rates of RTS after bilateral hip arthroscopy are lower than those after unilateral hip arthroscopy. When comparing patients that returned to sports and those who did not return, we show that although both groups show a significant improvement in PROs following surgery, those that returned to sport achieved significantly higher scores in all outcome measures. In addition, patients returning to sports showed a significantly higher rate of attaining MCID and PASS scores for the HOS-SSS, possibly attesting to the validity of this score and its thresholds.

Background: Prolonged disease chronicity has been implicated as a cause of suboptimal clinical outcomes after hip arthroscopy for femoroacetabular impingement syndrome (FAIS), possibly due to disease progression, deconditioning, and the development of compensatory pathomechanics. Purpose: To evaluate the effect of increasing duration of preoperative symptoms on patient-reported outcomes, reoperation, and clinical failure of hip arthroscopy for FAIS. Study Design: Cohort study; Level of evidence, 3. Methods: A retrospective cohort study was performed to identify all patients undergoing primary hip arthroscopy between January 1, 2012, and July 30, 2014, by a single surgeon, with minimum follow-up of 2 years. Patient demographics, comorbid medical conditions, and preoperative outcome scores were compared between patients with preoperative symptoms lasting less than 2 years and those with symptoms lasting 2 years or longer. Multivariate regressions were used to compare Hip Outcome Score Activities of Daily Living (HOS-ADL), Hip Outcome Score Sport-Specific (HOS-SS), and modified Harris Hip Score (mHHS) between the 2 cohorts at 2 years of follow-up. Results: A total of 624 patients were included, with an average age of 34.0 ± 13.5 years; 235 (37.7%) patients had experienced preoperative symptoms 2 years or longer. Patients with symptoms lasting less than 2 years had statistically significant higher outcome scores than those with symptoms lasting 2 or more years for the HOS-ADL (86.3 ± 16.4 vs 80.3 ± 19.9, respectively), HOS-SS (75.0 ± 25.3 vs 65.1 ± 29.0), and mHHS (79.1 ± 16.6 vs 74.0 ± 18.8), as well as higher satisfaction (82.1 ± 30.7 vs 71.1 ± 31.6) and lower pain scores (2.6 ± 2.3 vs 3.5 ± 2.6). On multivariate analysis, patients with symptoms 2 years or longer had significantly higher visual analog scale–Pain score (β = 0.6, P = .039) and lower HOS-ADL (β = −3.4, P = .033), HOS-SS (β = −6.3, P = .012), and satisfaction (β = −6.7, P = .028) at 2-year follow-up. Patients with longer duration of symptoms also demonstrated less improvement in HOS-SS (β = −10.3, P = .001) at 2 years after surgery. Patients with symptoms for 2 years or longer were significantly less likely to achieve a patient acceptable symptomatic state for HOS-ADL (relative risk [RR] = 0.8, P = .024) and HOS-SS (RR = 0.8, P = .032) at 2 years of follow-up. Patients with symptoms 2 years or longer also demonstrated significantly higher rates of revision arthroscopy (RR = 10.1, P = .046). Conclusion: Patients with untreated, FAIS-related symptoms lasting 2 years or longer before arthroscopic management had significantly worse patient-reported outcomes and higher rates of reoperation at 2 years after surgery when compared with those patients with a shorter duration of preoperative symptoms.

Background: Hip arthroscopy is a safe and effective mechanism for treating femoroacetabular impingement symptoms in high level athletes. Bilateral symptoms occur in a subset of this population. Purpose: To discuss outcomes of bilateral hip arthroscopy in high-level athletes and compare a standard staged timeline for bilateral hip arthroscopic surgery versus an accelerated timeline. Study Design: Cohort study; Level of evidence, 3. Methods: A retrospective review of all staged bilateral hip arthroscopies was performed on high-level athletes over a 3-year period. Patients were categorized into cohorts based upon when the second procedure was performed (4-6 weeks after the index procedure or >6 weeks after the index procedure). Exclusion criteria included any prior hip surgery, advanced arthritis, previous pelvic or femoral fracture, or inflammatory arthropathy. Demographics, radiographic measurements, operative reports of procedures performed, and patient-reported outcomes (Hip Outcome Score–Activities of Daily Living, Hip Outcome Score–Sport Specific Subscale, modified Harris Hip Score, return to sports, return to same level of play) were compared between groups at 6-month, 1-year, and 2-year intervals, with the Student t test used for continuous data and a chi-square test used for categorical data. Results: 50 patients were identified: 22 in the accelerated surgery (AS) group and 28 in the standard surgery (SS) group. Age and number of collegiate participants were greater in the AS group, whereas the number of high school participants and the time away from sports were higher in the SS group. Preoperative alpha angles were significantly larger among the AS group, but no differences were found in postoperative alpha angles, center edge angles, or Tönnis grades. No significant difference was seen in patient-reported outcomes between the 2 groups at 6-month, 1-year, and 2-year follow-up. Conclusion: Bilateral hip arthroscopy performed 4 to 6 weeks apart is a safe and effective treatment option for athletes with bilateral femoroacetabular impingement and labral tears; the procedures entail a high rate of return to sports, return to the same level of sports, and decreased time lost from sports. This information could be useful for an athlete deciding on whether to proceed with bilateral hip arthroscopy and deciding on the timing for the procedures.

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

Introduction:There is a paucity of literature examining the effects of alcohol consumption on patient-reported outcomes (PROs) after hip arthroscopy. The purpose of this study was to report 2-year outcomes of hip arthroscopy in patients who consume alcohol compared to patients who abstain.Methods:Registry data were prospectively collected and retrospectively reviewed to identify heavy drinkers at the time of primary hip arthroscopy. Patients were matched 1:1 (heavy drinkers:non-drinkers) based on age, sex, BMI, acetabular Outerbridge grade, and capsular treatment. All patients were assessed with 4 validated PROs: mHHS, NAHS, HOS-SSS, and iHOT-12. Pain was estimated with VAS.Results:42 patients were pair matched in each group (heavy drinkers:non-drinkers). Both groups demonstrated significant improvement for all PROs and VAS. Heavy drinkers reported lesser improvement in HOS-SSS ( p = 0.0169), smaller decrease in VAS ( p = 0.0157), and lower final scores on iHOT-12 ( p = 0.0302), SF-12 mental ( p = 0.0086), and VR-12 mental ( p = 0.0151). Significantly fewer patients in the heavy-drinking group reached PASS for mHHS ( p = 0.0464). Odds of achieving PASS for mHHS was 2.5 times higher for patients who abstain from alcohol. The rates of revision hip arthroscopy and conversion to total hip arthroplasty were not statistically different between groups.Conclusion:While hip arthroscopy may still yield clinical benefit in drinkers, patients who consume heavy amounts of alcohol may ultimately achieve an inferior functional status and should be counselled on drinking cessation to optimise their results.

Background: The clinical and radiographic features of iatrogenic hip instability following hip arthroscopy have been described. However, the prevalence of presenting symptoms and associated imaging findings in patients with hip instability has not been reported. Purpose: To detail the prevalence of clinical and magnetic resonance arthrogram (MRA) findings in a cohort of patients with isolated hip instability and to determine midterm patient-reported outcomes in this patient population. Study Design: Case series; Level of evidence, 4. Methods: We retrospectively reviewed patients from 2014 to 2016 who underwent an isolated capsular repair in the revision hip arthroscopy setting. Patients were excluded if they underwent any concomitant procedures, such as labral repair, reconstruction, femoral osteoplasty, or any other related procedure. Several clinical data points were reviewed, including painful activities, mechanical symptoms, subjective instability, Beighton scores, axial distraction testing (pain, toggle, and apprehension), and distractibility under anesthesia. Patient-reported outcomes—including modified Harris Hip Score, Hip Outcome Score–Sports Subscale, Patient-Reported Outcome Measurement Information System (PROMIS) Physical Function Computer Adaptive Test, and a return patient hip questionnaire—were collected pre- and postoperatively. Pre-revision radiographs were obtained, and lateral center-edge angle and alpha angle were measured on anteroposterior and frog-leg lateral views, respectively. Pre-revision MRAs were reviewed and evaluated for capsular changes. Capsular changes were defined as follows: 0, normal; 1, capsular redundancy; 2, focal capsular rent; and 3, gross extravasation of fluid from the capsule. Results: A total of 31 patients met inclusion criteria (5 male, 26 female; 14 right and 17 left hips). The mean age of patients was 36 years (range, 20-58 years). Overall, 27 (87%) reported hip pain with activities of daily living, and 31 (100%) experienced pain with sports or exercise. In addition, 24 (77%) had at least 1 positive finding on axial distraction testing. All patients had evidence of capsular changes on review of pre-revision MRAs. Out of 31 patients, 23 (74%) were available for follow-up at a minimum of 3.3 years and a mean ± SD of 4.6 ± 0.8 years. On average, modified Harris Hip Score improved by 20.3, Hip Outcome Score–Sports Subscale by 25.1, and PROMIS Physical Function Computer Adaptive Test by 6.4. Additionally, 20 (87%) patients reported improved or much improved physical ability, and 18 (78%) reported improved or much improved pain. Conclusion: The current study suggests that patients with hip instability demonstrate high rates of pain with activities of daily living and exercise, positive findings on axial distraction testing, and evidence of capsular changes on magnetic resonance imaging. Furthermore, these patients improve with revision surgery for capsular repair at midterm follow-up.

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