AB  - PURPOSE: (1) To investigate intra-articular damage in the hip joint associated 
      with subspine impingement (SSI); (2) to evaluate clinical outcomes of 
      arthroscopic treatment of hips with SSI; and (3) to compare the findings and 
      outcomes to a control group without SSI. METHODS: Eligible patients had 
      arthroscopic treatment for femoroacetabular impingement (FAI) concurrent with SSI 
      between January 2015 and December 2017. Inclusion criteria consisted of 
      preoperative and minimum 2-year patient-reported outcomes and preoperative 
      measurements for Tonnis, lateral center edge angle, and alpha angle. Included 
      patients were propensity-matched in a 1:3 ratio to patients who had FAI without 
      SSI. Patient-reported outcomes were compared between groups. Minimal clinically 
      important difference was calculated for modified Harris Hip Score (mHHS) and Hip 
      Outcome Score-Sports Specific Subscale (HOS-SSS). RESULTS: Fifty SSI cases were 
      matched to 150 patients who had FAI without SSI. A greater proportion of the SSI 
      cohort required labral reconstruction (P = .010). The size and locations for 
      labral tears and chondral defects were comparable between groups (P > .05). Both 
      groups demonstrated similar minimum 2-year outcomes for mHHS (P = .103), 
      Nonarthritic Hip Score (P = .200), HOS-SSS (P = .119), visual analog scale (P = 
      .231), international Hip Outcome Tool-12 (P =.300), Short Form-12 Mental 
      (P = .426), Short Form-12 Physical (P = .328), Veterans RAND 12-Item Health 
      Survey, Mental (P = .419), and Veterans RAND 12-Item Health Survey, Physical (P = 
      .316). The percentage of patients achieving minimal clinically important 
      difference for mHHS and HOS-SSS was similar (P > .05). Survivorship was 96.0% and 
      98.7% for the SSI and control cohorts at 2 years, respectively. CONCLUSIONS: 
      Arthroscopic treatment of hips with SSI with subspine decompression and 
      concomitant treatment of labral tears and FAI yielded significant improvement in 
      patients' outcomes, which compared favorably with the control group. SSI may 
      correlate with more complex labral tears, not amenable to repair, and complete 
      tears of the ligamentum teres. Other findings, such as location and size of 
      intra-articular damage, were similar between the cohorts. LEVEL OF EVIDENCE: III, 
      case-control study.
