AB  - BACKGROUND: Limited evidence exists comparing short- and long-term 
      patient-reported outcomes (PROs) and overall survival rates after hip arthroscopy 
      for femoroacetabular impingement syndrome (FAIS). HYPOTHESIS: Patients with high 
      improvement (HI) versus low improvement (LI) at 1 year postoperatively would 
      achieve higher PROs and better index procedure survival rates at 5-year 
      follow-up. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: Patients 
      who underwent primary hip arthroscopy for FAIS between September 2012 and March 
      2014 with minimum 5-year outcome data were identified. Using the median 1-year 
      change in modified Harris Hip Score (mHHS) as a threshold, HI and LI subcohorts 
      were determined. Analysis of variance was used to compare PROs. Failure rates 
      were determined using Kaplan-Meier and Cox proportional hazards model analyses. 
      Regression analysis was used to identify factors associated with increasing 
      5-year change in mHHS and Nonarthritic Hip Score (NAHS). RESULTS: Out of 108 
      eligible consecutive patients, 89 (82.4%) were included (mean [SD]: age, 43.3 
      [14.6] years; body mass index, 25.4 [4.5]). As compared with the LI group (n = 
      45), the HI group (n = 44) had a longer 5-year index surgery survival rate (mean 
      +/- SEM: 83.7 +/- 3.3 months vs 68.5 +/- 4.6 months; P = .012) and 5-year estimated 
      survival rate (89% vs 71%). The HI group had a decreased risk of failure versus 
      the LI group (hazard ratio, 0.15; P = .002). The HI group also had greater PROs 
      than did the LI group at 1 year (mHHS: 94.8 +/- 1.2 vs 72.6 +/- 2.7, P < .001; NAHS: 
      94.0 +/- 1.3 vs 75.6 +/- 2.2, P < .001) and 5 years (mHHS: 86.9 +/- 2.0 vs 77.6 +/- 3.4, 
      P = .017; NAHS: 92.6 +/- 1.8 vs 82.7 +/- 4.1, P = .020). As compared with the LI 
      group, the HI group achieved higher rates of the Patient Acceptable Symptomatic 
      State (PASS) and minimal clinically important difference (MCID) at 1 year (PASS: 
      95% vs 42%, P < .001; MCID: 100% vs 89%, P = .056) and 5 years (PASS: 77% vs 45%, 
      P = .002; MCID: 86% vs 64%, P = .014). Linear regression demonstrated that being 
      in the HI group (DeltamHHS, P = .041; DeltaNAHS, P = .017) and decreasing body mass index 
      (DeltamHHS, P = .055; DeltaNAHS, P = .023) were associated with higher 5-year DeltaPROs. 
      CONCLUSION: Patients with FAIS and significant improvement in the first year 
      after hip arthroscopy had superior 5-year outcomes versus patients with 
      persistent symptom severity. Survival rates and PROs were significantly better in 
      patients who achieved high early outcomes at the 1-year mark.
