Summary
Female patients across a wide range of ages, BMIs, and prior symptom histories experience satisfactory 5-year outcomes following primary hip arthroscopy, but higher BMI is a risk factor for reduced improvement.

Abstract
Purpose
The purpose of our study was to evaluate the impact of age, body mass index (BMI), and symptom duration on five-year clinical outcomes among females following primary hip arthroscopy for FAIS.
Methods
We conducted a retrospective review of a prospectively collected database of hip arthroscopy patients with minimum five-year follow-up. Subjects completed the modified Harris Hip Score (mHHS) and Non-Arthritic Hip Score (NAHS) prior to surgery and at five-year follow-up. Achievement rates for the minimum clinically-important difference (MCID), substantial clinical benefit (SCB), and patient acceptable symptom state (PASS) were calculated using published mHHS cutoff values. Pre-to-postoperative improvement in mHHS and NAHS was compared between groups using Mann-Whitney U-test or Kruskal-Wallis test. MCID/SCB/PASS achievement rates, reoperation rates, and total hip arthroplasty (THA) conversion rates were compared with Fisher’s exact test. Predictors of outcomes were identified using multivariable linear and logistic regression. P-values <0.05 were considered significant.
Results
103 patients were included in the analysis. Six reoperations (5.8%) and two conversions to THA (1.9%) were recorded. There were no significant differences in mHHS and NAHS improvement, achievement of the MCID, SCB, and PASS, or reoperation and THA rates between groups (p > 0.05). However, higher BMI was an independent predictor of lower five-year improvement in mHHS (ß = -1.20, p < 0.001) and NAHS (ß = -1.43, p = 0.001) and for lower odds of achieving the MCID (OR = 0.83, p = 0.03) and SCB (OR = 0.87, p = 0.01) but not the PASS (OR = 0.92, p = 0.07).
Conclusions
Female patients across a wide range of ages, BMIs, and prior symptom histories experience satisfactory five-year outcomes following primary hip arthroscopy, but higher BMI is a risk factor for reduced improvement in patient-reported outcomes and lower MCID, SCB, and PASS achievement rates, independent of age and symptom duration.
