AB  - PURPOSE: The purpose of this study was to compare outcomes after hip arthroscopy 
      for femoroacetabular impingement syndrome (FAIS) in patients with borderline hip 
      dysplasia and hip instability defined radiographically using the femoroepiphyseal 
      acetabular roof (FEAR) index and in patients without radiographic evidence of hip 
      instability. METHODS: Data from consecutive patients with borderline hip 
      dysplasia (lateral center edge angle between 18 -25 ) who underwent primary hip 
      arthroscopy between April 2012 and June 2017 for the treatment of FAIS were 
      analyzed. Baseline demographic data, radiographic parameters, preoperative, and 
      2-year postoperative patient-reported outcome measures were collected. The FEAR 
      index was measured by 3 different observers. Patients with an average FEAR index 
      >/=2  were categorized as having radiographic evidence of instability as previously 
      published. The analysis was powered to detect a minimal clinically important 
      difference (MCID) for each outcome score. Statistical analysis was performed as 
      appropriate to compare patients with FEAR index >/=2 and <2 degrees . RESULTS: A total of 
      140 patients met the inclusion criteria. The average age and body mass index of 
      included patients was 31.7 +/- 13.2 (P < .325) years and 25.1 +/- 5.6 kg/m(2) (P < 
      .862). There were no statistically significant demographic differences between 
      the groups. Nineteen (13.0%) patients were found to have a FEAR index of over 2 . 
      The FEAR index <2 degrees  and FEAR index >/=2 degrees  groups had a mean preoperative FEAR index 
      (standard deviation, range) of -7.0 (5.2, -26.8 to 1.9) and 4.8 (2.5, 2.0-11.8), 
      respectively. The interrater intraclass correlation coefficient was 0.96. 
      Postoperative patient-reported outcomes and rates of MCID and patient-acceptable 
      symptomatic state achievement were not statistically different between the 
      radiographically stable and unstable groups. (p>0.05 for all). CONCLUSION: 
      Patients with borderline hip dysplasia and radiographic evidence of hip 
      instability, as measured by the FEAR index (>/=2 degrees ), achieve similar improvement in 
      2-year outcomes compared to those with radiographically stable hips after 
      arthroscopic treatment of FAIS. CLINICAL RELEVANCE: Retrospective Level III 
      cohort study.
