AB  - PURPOSE: To compare outcomes of borderline hip dysplasia (BHD) patients 
      undergoing revision hip arthroscopy with 1) patients with BHD undergoing primary 
      hip arthroscopy for femoroacetabular impingement syndrome (FAIS) and 2) patients 
      without BHD undergoing revision hip arthroscopy for FAIS. METHODS: A 
      retrospective cohort study was performed to identify patients who underwent 
      arthroscopy from January 2012 to January 2016 by a single fellowship-trained 
      surgeon, including a 2-year follow-up. Patient demographics, comorbid medical 
      conditions, and preoperative outcome scores were compared between patients with 
      BHD (lateral center-edge angle 18 degrees  to 25 degrees ) who had revision hip arthroscopy to 
      patients with BHD undergoing primary arthroscopy and patients without BHD 
      (lateral center-edge angle >25 degrees ) undergoing revision arthroscopy. Cohorts were 
      matched 2:1 by age and body mass index. Multivariate regressions were used to 
      compare Hip Outcome Score, Activities of Daily Living subscale (HOS-ADL) and 
      Sports subscale (HOS-SS) scores and modified Harris Hip Score (mHHS) between the 
      cohorts at 2-year follow-up. Binomial regression analysis was used to determine 
      predictors of achieving minimal clinically important difference (MCID) and 
      patient-acceptable symptom state (PASS). RESULTS: There was no statistical 
      difference in age and BMI between the BHD revision (29.1 +/- 8.8 years; 25.5 
      +/- 3.58 kg/m(2)), BHD nonrevision (28.9 +/- 8.5 years; 24.6 +/- 3.1 kg/m(2)), and 
      non-BHD revision (29.15 +/- 8.6 years; 25.01 +/- 3.2 kg/m(2)) cohorts. There were no 
      statistically significant differences in 2-year clinical outcomes between BHD 
      revision patients and either BHD primary or non-BHD revision patient groups, but 
      BHD revision patients were significantly less likely to achieve PASS for HOS-SS 
      compared with BHD primary and non-BHD revision groups (P = .047 and P = .031, 
      respectively). CONCLUSION: Surgeons should exercise caution when indicating 
      patients for revision hip arthroscopy with BHD. Although the current study lacks 
      statistical power, the available data suggest that patients undergoing revision 
      surgery with BHD may still experience clinical improvement but be less likely to 
      achieve PASS metrics for several patient-reported outcomes at 2-year follow up. 
      LEVEL OF EVIDENCE: III, case-control study.
