Females and Males Achieve Similar Improvement, Outcomes, and Survivorship Following Hip Arthroscopy with Labral and Capsular Repair for Femoroacetabular Impingement Syndrome at Minimum 10-Year Follow-Up.

ABSTRACT

PURPOSE: To evaluate the effect of patient sex on 10-year patient-reported outcomes (PROs) and survivorship after hip arthroscopy (HA) for femoroacetabular impingement syndrome (FAIS). METHODS: Patients who underwent primary HA for FAIS with minimum 10-year follow-up from 1/2012-12/2013 were retrospectively reviewed. Female patients were propensity-matched to male patients in a 11 ratio by age and body mass index. PROs and rates of minimal clinically important difference (MCID) and patient-acceptable symptom state (PASS) achievement were compared between cohorts. Rate of reoperation-free survivorship was compared between sexes. RESULTS: One-hundred and twenty-one- females (age 36.2 ± 12.3 years) were matched to 121 males (age 35.7 ± 11.3 years, p = 0.594) at average follow-up of 10.4 ± 0.4 years. There were no differences in any preoperative demographic characteristics between the groups (p ≥ 0.187). Both groups demonstrated significant improvement in every PRO measure between the preoperative and 10-year postoperative time points (p < 0.001). The magnitude of improvement was similar between the groups for all PRO measures (p ≥ 0.139). At 10-years, female patients trended towards higher MCID achievement for the Hip Outcome Score-Activities of Daily Living subscale (HOS-ADL) than male patients (72.7% vs. 57.3%, p = 0.061), with otherwise similar MCID achievement rates. Females trended towards significantly lower HOS-Sports Subscale PASS achievement (65.4% vs. 77.1%, p = 0.121) with otherwise similar PASS achievement rates between the groups (p ≥ 0.170). CONCLUSION: Female and male patients experienced similar improvement in PROs at ten-year follow-up. MCID and PASS achievement rates were predominantly similar between sexes. Survivorship did not differ between groups. Long-term success can be expected for appropriately indicated patients undergoing HA for FAIS, regardless of sex.
