AB  - BACKGROUND: Although patients have experienced significant improvements after hip 
      arthroscopy for femoroacetabular impingement (FAI), prior studies suggest that 
      women have worse outcomes than men. These previous studies lack comparisons of 
      patient-reported outcome (PRO) scores based on gender with respect to clinical 
      significance measurements, including the minimal clinically important difference 
      (MCID) and patient acceptable symptom state (PASS). PURPOSE: To evaluate outcomes 
      after hip arthroscopy for FAI based on patient gender by prospectively assessing 
      changes in PRO scores, MCID, and PASS. STUDY DESIGN: Cohort study; Level of 
      evidence, 2. METHODS: Women and men undergoing hip arthroscopy for FAI were 
      prospectively enrolled, and preoperative radiographic and intraoperative findings 
      were collected. Patients completed the following PRO surveys before surgery and 2 
      years postoperatively: modified Harris Hip Score (mHHS), Hip disability and 
      Osteoarthritis Outcome Score (HOOS), and 12-Item Short Form Health Survey. Mean 
      scores and percentage of patients reaching MCID and PASS were analyzed. RESULTS: 
      A total of 131 hips were included (72 women, 59 men). Women had smaller 
      preoperative alpha angles (59.1 degrees  vs 63.7 degrees , respectively; P < .001) and lower 
      acetabular cartilage injury grade (6.9% vs 22.0% with grade 4 injury, 
      respectively; P = .013). Both women and men achieved equivalent significant 
      improvements in PRO scores after surgery (scores increased 18.4 to 45.1 points 
      for mHHS and HOOS). Women and men reached PASS for mHHS at similar rates (76.4% 
      and 77.2%, respectively; P = .915). MCID was also achieved at similar rates 
      between women and men for all scores (range, 61.4%-88.9%) except the activities 
      of daily living subscale of the HOOS, in which a greater percentage of women 
      reached MCID compared with men (79.2% vs 62.7%, respectively; P = .037). 
      Additional stratification by age group using the median cohort age of 34 years 
      showed no significant differences in PRO improvement based on age group for each 
      gender. CONCLUSION: Women can achieve clinically meaningful improvements in PRO 
      scores after hip arthroscopy for FAI. Compared with men, women demonstrated 
      equivalent high rates of achieving MCID and PASS at 2 years after surgery.
