The Impact

Background: Measures of clinically meaningful improvement in patient-reported outcomes within orthopaedics are becoming a minimum requirement to establish the success of an intervention. Purpose: To (1) define the minimal clinically important difference (MCID) at 2 years postoperatively in competitive athletes undergoing hip arthroscopic surgery for symptomatic, sports-related femoroacetabular impingement utilizing existing anchor- and distribution-based methods and (2) derive a measure of the MCID using the percentage of possible improvement (POPI) method and compare against existing techniques. Study Design: Cohort study (diagnosis); Level of evidence, 2. Methods: There were 2 objective outcome measures—the modified Harris Hip Score (mHHS) and 36-Item Short Form Health Survey (SF-36)—administered at baseline and 2 years postoperatively. External anchor questions were used to determine the MCID through mean change, mean difference, and receiver operating characteristic (ROC) techniques. Distribution-based calculations consisted of 0.5 SD, effect size, and standard error of measurement techniques. The POPI was calculated alongside each technique as an achieved percentage change of maximum available improvement for each athlete relative to the individual baseline score. The impact of the preoperative baseline score on the MCID was assessed by assigning athletes to groups determined by baseline percentiles. Statistical analysis was performed, with P < .05 considered significant. Results: There were 576 athletes (96% male; mean age, 25.9 ± 5.7 years). The MCID score change (and POPI) for the mHHS and SF-36 ranged from 2.4 to 16.7 (21.6%-63.6%) and from 3.3 to 24.9 (22.1%-57.4%), respectively. The preoperative threshold value for achieving the ROC-determined MCID was 80.5 and 86.5 for the mHHS and 70.1 and 72.4 for the SF-36 for the patient-reported outcome measure (PROM) score– and POPI-calculated MCID, respectively. Through the commonly used mean change method, 40.0% (mHHS) and 42.4% (SF-36) of athletes were unable to achieve the MCID because of high baseline scores and PROM ceiling effects compared with 0% when the POPI technique was used. A highly significant difference for the overall MCID was observed between preoperative baseline percentile groups for the mHHS ( P = .014) and SF-36 ( P = .004) (improvement in points), while there was no significant difference between groups for either the mHHS ( P = .487) or SF-36 ( P = .417) using the POPI technique. Conclusion: The MCID defined by an absolute value of improvement was unable to account for postoperative progress in a large proportion of higher functioning athletes. The POPI technique negated associated ceiling effects, was unrestricted by the baseline score, and may be more appropriate in quantifying clinically important improvement.

Background: A growing body of literature supports surgical intervention for femoroacetabular impingement (FAI) in young, active athletes. However, factors likely to influence results in this cohort are less clearly defined. Purpose: To quantify changes in validated patient-reported outcome measures (PROMs) and determine whether differences in baseline athlete demographic characteristics, intraoperative findings, and surgical techniques are associated with achieving improved outcomes and minimal clinically important difference (MCID) after arthroscopic management of sports-related FAI. Study Design: Case series; Level of evidence, 4. Methods: Data were prospectively collected from competitive athletes who underwent hip arthroscopy between January 2009 and February 2017. Athletes who underwent primary arthroscopic correction of sports-related FAI with labral repair were included providing they had a Tönnis grade ≤1 and a lateral center-edge angle ≥20°, excluding significant articular cartilage injury and lateral rim dysplasia. The modified Harris Hip Score, Western Ontario and McMaster Universities Osteoarthritis Index, University of California Los Angeles activity scale, and 36-Item Short Form Health Survey were used to measure outcomes at the 2-year follow-up. MCID was measured using 3 methods: a mean change method, a distribution-based method, and the percentage of possible improvement (POPI) method. Multivariate regression models were used to assess a number of diagnostic and surgical variables associated with good outcome and achieving MCID at follow-up. Results: At 2-year follow-up, statistically significant improvements were observed for all PROMs ( P < .001 for all), and 84% of athletes continued to play sport. Higher preoperative PROM scores reduced the likelihood of achieving MCID; however, returning to play was the strongest predictor of reaching MCID in this athletic cohort. Using absolute score change (mean change or distribution method) to calculate MCID was less accurate owing to ceiling effects and dependence on preoperative PROM scores. Conclusion: Athletes undergoing arthroscopy for sports-related FAI can expect a successful outcome and continued sports participation at 2 years postoperatively. The majority of athletes will achieve MCID. The POPI method of MCID calculation was more applicable to higher functioning athletic cohorts. Reduced preoperative PROM scores and the ability to return to sport increased the likelihood of achieving MCID in this population.

Background: Endoscopic surgical repair has become a common procedure for treating patients with gluteus medius tears. However, meaningful clinical outcomes after the procedure have not been defined. Purpose: To (1) define the minimal clinically important difference (MCID) and patient acceptable symptomatic state (PASS) in patients undergoing endoscopic gluteus medius repair and (2) determine correlations between preoperative patient characteristics and achievement of MCID/PASS. Study Design: Case series; Level of evidence, 4. Methods: A retrospective review was performed of prospectively collected data from all patients undergoing primary endoscopic repair of gluteus medius tears between January 2012 and February 2017 with a minimum 2-year follow-up. Patient data collected included patient characteristics, radiographic parameters, preoperative clinical function scores, and postoperative patient-reported outcomes (PROs). Paired t tests were used to compare the differences in 2-year PROs. The MCID and PASS for each PRO were calculated and Spearman coefficient analysis was used to identify correlations between MCID, PASS, and preoperative variables. Results: A total of 60 patients were included in the study. A majority of patients were female (91.7%), with an average age and body mass index of 57.9 ± 9.91 years and 27.6 ± 6.1, respectively. The MCIDs of the Activities of Daily Living (ADL) and Sport-Specific (SS) subscales of the Hip Outcome Score (HOS) and the modified Harris Hip Score (mHHS) were calculated to be 15.02, 14.53, and 14.13, respectively. The PASS scores of HOS-ADL, HOS-SS, and mHHS were calculated to be 81.32, 67.71, and 77.5, respectively. In addition, 76.7% of patients achieved either MCID or PASS postoperatively, with 77.8% and 69.0% reaching at least 1 threshold score for achieving MCID and PASS, respectively, and 48.3% achieving both MCID and PASS. Smoking had a negative and weak association with achieving PASS ( r = −0.271; P = .039). No other patient characteristic variables were found to correlate with achieving MCID or PASS. Conclusion: In patients undergoing endoscopic gluteus medius repair, our study defined MCID and PASS for HOS-ADL, HOS-SS, and mHHS outcome scores. A large percentage of patients (76.7%) achieved meaningful clinical outcomes at 2 years after surgery.

Abstract One in four patients presenting with femoroacetabular impingement (FAI) has bilateral symptoms, and despite excellent outcomes reported after arthroscopic treatment of FAI, there remains a paucity of data on the outcomes following bilateral hip arthroscopy. This systematic review aims to examine the outcomes following bilateral (either ‘simultaneous’ or ‘staged’) versus unilateral hip arthroscopy for FAI. A systematic review of multiple electronic databases was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and checklist. All studies comparing simultaneous, staged and/or unilateral hip arthroscopy for FAI were eligible for inclusion. Case series, case reports and reviews were excluded. All study, patient and hip-specific data were extracted and analyzed. The Newcastle–Ottawa Scale was used to assess study quality. A meta-analysis was not performed due to heterogeneity among outcome measures. A total of six studies, including 722 patients (42.8% male) and 933 hips were eligible for inclusion. The mean age across patients was 35.5. The average time between staged procedures was 7.7 months. Four of the six studies were retrospective cohort studies, while the remaining two were prospective in nature. The overall quality of the eligible studies was found to be good. No significant difference was noted among patient-reported outcomes (modified Harris hip score, hip outcome score and non-arthritic hip score), visual analog scale, return to sport, traction time and complications between those undergoing bilateral (simultaneous or staged) versus unilateral hip arthroscopy. Based on the current available evidence, bilateral hip arthroscopy (whether simultaneous or staged) exhibits similar efficacy and safety when compared with unilateral hip arthroscopy. However, further prospective study is required to confirm this finding.

ABSTRACT There is a paucity of literature on patient-reported outcome measures (PROMs) following proximal hamstring repair beyond return to play, patient satisfaction and pain improvement. The minimal clinically important difference (MCID) defines the minimum degree of quantifiable improvement that a patient can perceive, but the MCID and predictors of this measure have not been defined for this patient population. This study aimed to define the MCID and determine the efficacy of open proximal hamstring repair through achievement of MCID and identify characteristics predictive of achieving MCID. A retrospective cohort review of an institutional hip registry was conducted, analyzing the modified Harris Hip Score (mHHS) and International Hip Outcome Tool (iHOT-33). MCID was calculated using a distribution-based method. Demographic and clinical variables predictive of achieving MCID were analyzed using univariable and multivariate logistic regression analyses. Thirty-nine patients who underwent open proximal hamstring repair were included. The mean patient age was 48.5 ± 12.4 years, with a mean follow-up of 37.1 ± 28 months. The MCID was determined for each PROM (mHHS—11.8; iHOT-33—12.6). A high percentage of patients achieved MCID for both PROMs (mHHS—85.7%; iHOT-33—91.4%). Univariate logistical regression demonstrated increased age (P = 0.163), increased body mass index (BMI; P = 0.072), requirement for inpatient admission (P = 0.088) and pre-operative iHOT-33 (P = 0.104) trended towards clinically significant predictors of not achieving MCID. A high percentage of patients achieved MCID while age, BMI, inpatient admission and pre-operative iHOT-33 appear to influence the achievement of clinically significant outcome in patients undergoing open proximal hamstring repair.

Survivorship Rate

Background: Femoroacetabular impingement (FAI) is a common mechanical hip condition, prevalent in both the athletic and the general population. Surgical intervention is an effective treatment option that improves both symptoms and function in short- to medium-term follow-up. Few studies within the literature have reported the longer-term success of arthroscopic surgery. Purpose: The aim of this study was to quantify the 10-year survivorship and clinical outcome for patients treated arthroscopically for symptomatic FAI. Study Design: Case series; Level of evidence, 4. Methods: Patients from our hip registry (n = 119) completed patient-reported outcome measures (PROMs) including the modified Harris Hip Score (mHHS), University of California Los Angeles (UCLA) activity scale, 36-Item Short Form Health Survey (SF-36), and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) at a minimum of 10 years after arthroscopy (range, 10-12 years). Results were compared with baseline scores using the Wilcoxon signed rank test. The associations among several prognostic factors, which included age, sex, Tönnis grade, and labral treatment, and subsequent conversion to total hip replacement (THR) or repeat hip arthroscopy (RHA) were analyzed using the chi-square analysis. Relationships between range of motion and radiological findings with clinical outcome were also examined using Pearson correlation analysis. Minimal clinically important difference (MCID) was calculated using a distribution method (0.5 standard deviation of the change score), and substantial clinical benefit (SCB) was determined using an anchor method. Finally, receiver operating characteristic curves with subsequent Youden index were used to determine cutoffs for PROMs, which equated to a Patient Acceptable Symptom State (PASS). Results: A total of 8.4% of cases required conversion to THR, and 5.9% required RHA. Statistically significant improvements in mHHS, SF-36, and WOMAC scores, with high satisfaction (90%), were observed 10 years after surgery. No significant change was seen in activity level (UCLA score) despite patients being 10 years older. A high percentage of patients achieved MCID for mHHS (88%), SF-36 (84%), and WOMAC (60%). The majority of patients also achieved PASS (62% for mHHS, 85% for UCLA, 78% for SF-36, and 84% for WOMAC) and SCB (74% for mHHS, 58% for UCLA, 52% for SF-36, and 56% for WOMAC). Conclusion: Arthroscopic intervention is a safe and viable treatment option for patients with symptomatic FAI, and patients can expect long-term improvements and high satisfaction. Results indicated a high satisfaction (90%) and survivorship rate (91.6%), with excellent clinical outcome, 10 years after the initial procedure.

The Impact

Background Arthroscopic debridement is the standard of care for the treatment of acetabular labral tears. The Short Form-36 has not been used to measure hip arthroscopy outcomes, and the impact of disability status on hip arthroscopy outcomes has not been reported. Hypothesis Short Form-36 subscale scores will demonstrate good correlation with the modified Harris hip score, but patients undergoing disability evaluation will have significantly worse outcome scores. Study Design Case series; Level of evidence, 4. Methods The records of active-duty soldiers who underwent hip arthroscopy at the authors’ institution were retrospectively reviewed. Forty consecutive patients who underwent hip arthroscopy for the primary indication of labral tear formed the basis of the study group. Patients completed the modified Harris hip score, the Short Form-36 general health survey, and a subjective overall satisfaction questionnaire. Results Thirty-three patients, with a mean age of 34.6 years, were available for follow-up at a mean of 25.7 months postoperatively. Fourteen (43%) patients were undergoing medical evaluation boards (military equivalent of workers’ compensation or disability claim). Pearson correlation coefficients for comparing the Short Form-36 Bodily Pain, Physical Function, and Physical Component subscale scores to the modified Harris hip score were 0.73, 0.71, and 0.85, respectively (P <. 001). The mean modified Harris hip score was significantly lower in patients on disability status than in those who were not (92.4 vs 61.1; P <. 0001). The Short Form-36 subscale scores were significantly lower in disability patients (P <. 02). Patient-reported satisfaction rates (70% overall) were 50% for those undergoing disability evaluations and 84% for those who were not (P <. 04). There was no significant difference in outcomes based on patient age, surgically proven chondromalacia, or gender for military evaluation board status. Conclusion The Short Form-36 demonstrated good correlation with the modified Harris hip score for measuring outcomes after arthroscopic partial limbectomy. Arthroscopic debridement yielded a high percentage of good results when patients undergoing disability evaluations were excluded. Disability status may be a negative predictor of success after hip arthroscopy.

Background: There is a paucity in the literature reporting patient-reported outcome (PRO) scores and the minimal clinically important difference (MCID) after revision hip arthroscopic surgery with circumferential labral reconstruction. Purpose: To report minimum 2-year PRO scores and the rate of achieving the MCID in patients who underwent revision hip arthroscopic surgery with circumferential labral reconstruction in the setting of irreparable labral tears. Study Design: Case series; Level of evidence, 4. Methods: Data were retrospectively reviewed for all patients who underwent revision hip arthroscopic surgery between February 2016 and November 2017. Patients were included if they had undergone circumferential labral reconstruction and had preoperative and postoperative scores for the modified Harris Hip Score (mHHS), Non-Arthritic Hip Score (NAHS), Hip Outcome Score Sport-Specific Subscale (HOS-SSS), International Hip Outcome Tool (iHOT-12), 12-Item Short Form Health Survey physical and mental components (SF-12 P and SF-12 M, respectively), Veterans RAND 12-Item Health Survey physical and mental components (VR-12 P and VR-12 M, respectively), and visual analog scale (VAS) for pain. Exclusion criteria were Tönnis grade >1, Legg-Calve-Perthes disease, slipped capital femoral epiphysis, fractures, hip dysplasia, or revision labral treatment different from circumferential labral reconstruction. The MCID was calculated. Secondary surgical procedures were documented. Results: A total of 26 hips (26 patients; 61.5% female) were included. The mean age and body mass index were 33.2 ± 10.4 years and 25.5 ± 4.9, respectively. Significant improvements were reported for the mHHS (17.0 ± 19.5; P = .0002), NAHS (17.9 ± 16.7; P < .0001), HOS-SSS (21.7 ± 23.1; P = .0005), VAS (–2.2 ± 3.0; P = .006), iHOT-12 (25.8 ± 32.5; P = .0007), SF-12 P (8.5 ± 11.2; P = .001), and VR-12 P (8.9 ± 11.6; P = .001). Rates of meeting the MCID for the mHHS, NAHS, HOS-SSS, iHOT-12, and VAS were 76.9%, 80.0%, 65.0%, 62.5%, and 69.2%, respectively. No case of re-revision arthroscopic surgery was documented, but 1 case of conversion to total hip arthroplasty was documented at 38.6 months. Conclusion: In the setting of revision hip arthroscopic surgery and irreparable labral tears, circumferential labral reconstruction resulted in significant improvements in all PRO and VAS scores at a minimum 2-year follow-up with a high rate of achieving the MCID.

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: Limited evidence exists concerning the effect of age on hip arthroscopy outcomes for femoroacetabular impingement (FAI). Purpose/Hypothesis: The purpose was to investigate patient-reported outcomes (PROs) and clinical failure rates across various age groups in patients undergoing hip arthroscopy for FAI. We hypothesized that older patients would experience lower improvements in PROs and higher clinical failure rates. Study Design: Cohort study; Level of evidence, 3. Methods: A total of 109 of 130 eligible consecutive patients underwent hip arthroscopy for FAI with a minimum 5-year follow-up. Patients were stratified into 3 groups for comparison (ages 15-34, 35-50, and 51-75 years). Clinical survival rates to revision surgery or total hip arthroplasty (THA) were determined by Kaplan-Meier analysis, and PROs were assessed using analysis of variance. Regression analysis was used to determine factors associated with clinical failure and ΔPROs from baseline to 5 years. Results: The 5-year survival-to-revision rate was 71% (survival time, 69.2 months; 95% CI, 62.8 to 75.5 months). A significant difference in survival to THA was found between groups ( P = .030). Being in the older group versus the young and middle-aged groups predicted increased risk of THA conversion (hazard ratio, 5.7; 95% CI, 1.1 to 28.6; P = .035). Overall modified Harris Hip Score (mHHS) and Nonarthritic Hip Score (NAHS) improved from baseline to 5 years (mHHS, P < .001; NAHS, P < .001). Body mass index (mHHS: beta, −1.2; 95% CI, −2.2 to −0.3; P = .013; NAHS: beta, −1.6; 95% CI, −2.6 to −0.5; P = .005) and baseline PROs (mHHS: beta, −0.8; 95% CI, −1.1 to −0.4; P < .001; NAHS: beta, −0.7; 95% CI, −1.1 to −0.4; P < .001) were predictive of 5-year ΔPROs. A decrease was seen in minimal clinically important difference rates in middle-aged ( P = .011) and old ( P = .030) groups from 6-month to 5-year outcomes. Conclusion: Although hip arthroscopy for FAI yielded improvements in PROs regardless of age, middle-aged and older patients experienced greater declines in clinical outcomes over time than younger patients. Older patients remain good candidates for arthroscopy despite a greater risk for conversion to THA.

Background: There is a lack of midterm or long-term outcome data on nonoperative management of femoroacetabular impingement (FAI) syndrome in adolescents despite expanding research mostly focused on arthroscopic management. Purpose: To present 5-year outcome data utilizing a nonoperative protocol on a consecutive series of patients presenting to our clinic with FAI syndrome. Study Design: Cohort study, Level of evidence, 2. Methods: A total of 100 patients (62% female; mean age 15 years) who presented to the clinic for evaluation of hip pain and had at least 1 hip with a positive impingement sign were prospectively recruited. The management protocol consisted of an initial trial of rest, physical therapy, and activity modification. Patients who remained symptomatic were offered an intra-articular steroid injection. Patients with recurrent symptoms were then offered arthroscopic treatment. Patient-reported outcomes (PROs), including the modified Harris Hip Score (mHHS) and the Nonarthritic Hip Score (NAHS) were then collected at a mean 1, 2, and 5 years after the initial evaluation. Results: At enrollment, the mean mHHS and NAHS were 69.6 ± 12.9 and 75.5 ± 15.2, respectively. A total of 51 patients (n = 69 hips) were available at a mean 5-year follow-up, with the mean mHHS and NAHS of 89.5 ± 10.8 and 88.1 ± 12, respectively. There was no significant difference in the mHHS or the NAHS between activity modification and physical therapy, injection, or arthroscopic surgery groups at 5-year follow-up ( P > .6) and no difference in the proportion of hips meeting the minimal clinically important difference (MCID) for the mHHS based on treatment course ( P = .99). There was no significant difference in the mHHS or the NAHS between FAI types at any time point, or in the proportion of hips that met the MCID among FAI types ( P = .64). Also, 11 out of 12 hips that required surgery had surgery in less than 2 years. One hip underwent surgery at 5 years after the initial visit. There was no significant drop-off in the mHHS or the NAHS between the 2-year and 5-year time periods ( P > .3). Conclusion: Nonoperative management of FAI syndrome is effective in a majority of adolescent patients, with significant improvements in PROs persisting at a mean 5-year follow-up.
