      Repair.

AB  - BACKGROUND: While labral repair has been widely adopted as the first line 
      treatment for labral injury during hip arthroscopy, there is no widespread 
      consensus on the procedural technique, including the number of anchors that 
      should be used to avoid recurrent instability and revision surgery. PURPOSE: To 
      determine if anchor density can predict patient-reported outcomes after 
      arthroscopic labral repair in the hip. STUDY DESIGN: Cohort study; Level of 
      evidence, 3. METHODS: Patients aged 18 to 50 years who underwent primary hip 
      arthroscopic surgery with labral repair between January 2011 and December 2016 
      were identified from a prospectively collected database. Exclusion criteria 
      consisted of previous ipsilateral surgery, osteoarthritis (Tonnis grade >1), and 
      severe cartilage defects (Outerbridge grade III/IV) or concomitant labral 
      reconstruction, capsular reconstruction, or microfracture. Minimum 2-year 
      patient-reported outcomes (modified Harris Hip Score [mHHS], Hip Outcome Score 
      [HOS]-Activities of Daily Living [ADL], HOS-Sport Specific Subscale [SSS], 
      12-Item Short Form Health Survey [SF-12]), rates of achieving the minimal 
      clinically important difference (MCID) and patient acceptable symptom state 
      (PASS) for each score, revision surgery rate, and rate of conversion to total hip 
      arthroplasty (THA) were compared based on anchor density (number of anchors per 
      millimeter of labral tear). RESULTS: A total of 634 hips (575 patients) with a 
      mean age of 30.4 +/- 9.5 years (range, 18.0-49.9 years) met inclusion criteria. The 
      mean labral tear size was 31 +/- 11 mm (range, 2-70 mm) with a median number of 
      anchors used for labral repair of 3 (range, 1-7) and mean anchor density of 0.11 
      +/- 0.08 anchors (range, 0.03-1.33) per millimeter of labral tear. Hips with a 
      minimum 2-year follow-up (451/634 [71.1%]) had significant improvements on the 
      mHHS, HOS-ADL, HOS-SSS, and SF-12 Physical Component Summary (P < .001 for all). 
      There was no significant correlation detected between anchor density or number of 
      anchors used and postoperative scores (correlation coefficient range, -0.05 to 
      0.17; P > .05 for all). The rate of revision surgery was 6.4% (28 patients), with 
      8 hips found to have labral tears and/or deficiency on revision. Additionally, 6 
      hips (1.3%) had to undergo THA at a mean of 3.6 +/- 2.1 years (range, 2.0-5.5 
      years). CONCLUSION: Anchor density did not have a correlation with postoperative 
      outcomes, achieving the MCID or PASS, revision hip arthroscopic surgery, 
      complications, or conversion to THA.
