AB  - The aim of this article is to examine the results of arthroscopic management of 
      patients with labral pathology who have preoperative magnetic resonance images 
      (MRIs) demonstrating subchondral cysts. This institution's database was searched 
      for patients who underwent hip arthroscopy and had subchondral cysts on MRI 
      and >2-year follow-up. Exclusion criteria included previous hip surgery, Tonnis 
      grade >1, inflammatory arthritis, Perthes, slipped capital femoral epiphysis or 
      abductor repair. Patient-reported outcome (PRO) scores including visual analog 
      scale, modified Harris hip score (mHHS), non-arthritic hip score and hip outcome 
      score sports-specific subscale (HOS-SSS) were gathered preoperatively, at 
      3 months, and annually thereafter. The change in PRO scores was compared with the 
      minimally clinical important difference (MCID) to quantify improvement. 
      Sixty-nine patients were eligible for this study, of which 65 (94%) had >2-year 
      follow-up. All PROs were significantly improved at latest follow-up (P < 0.001). 
      Mean patient satisfaction was 7.2. There was no correlation between Outerbridge 
      grade III or IV cartilage damage noted during arthroscopy and subchondral femoral 
      and acetabular cysts noted on MRI. Seventeen patients required reoperation [13 
      total hip arthroplasty (THAs) and 4 revision arthroscopies]. Patients with 
      femoral subchondral cysts converted to THA 36% of the time. MCIDs for mHHS and 
      HOS-SSS were surpassed by 63% and 68% of patients, respectively. Hip 
      arthroscopies performed on patients with subchondral cysts present on 
      preoperative MRI should be approached with caution. The rate of conversion to hip 
      arthroplasty appears to be higher than that reported in the literature for 
      patients who undergo arthroscopy without preoperative subchondral cysts. For 
      patients who did not require hip arthroplasty or revision arthroscopy, patients 
      demonstrated significant improvement in symptoms compared with the preoperative 
      state.
