AB  - PURPOSE: To define minimal clinically important difference (MCID) and substantial 
      clinical benefit (SCB) in revision hip arthroscopy. METHODS: The modified Harris 
      Hip Score (mHHS), the Hip Outcome Score (HOS), and the international Hip Outcome 
      Tool (iHOT-33) were administered to revision hip arthroscopy patients. At 1 year 
      postoperatively, patients graded their hip function based on anchor responses. 
      SCB was defined as both a net change and an absolute value. Receiver operating 
      characteristic analysis with area under the curve was used to confirm 
      psychometric values. A distribution-based method was used for MCID. RESULTS: 
      Forty-nine patients were included with a mean age of 29.7 (+/-8.6) years. The most 
      common indication for revision hip arthroscopy was residual femoroacetabular 
      impingement (FAI; N = 34; 69.4%) followed by capsular management (N = 8; 16.3%). 
      At 1-year follow-up, 34 patients reported feeling improved. Outcome score change 
      corresponding to MCID and SCB net change for the mHHS, HOS Activities of Daily 
      Living (ADL), HOS Sports, and iHOT-33 was 7.9/23.1, 7.9/16.2, 13.1/25.0, and 
      12.8/25.5, respectively. A higher proportion of patients with residual FAI 
      achieved MCID compared with patients with other diagnoses. On the preoperative 
      HOS ADL, HOS Sports, and iHOT-33, patients scoring below 67.7 (0.78), 55.6 
      (0.81), and 35.7 (0.73) were significantly more likely to achieve SCB 
      postoperatively. Thirty-four patients (73.9%) were classified as receiving 
      physical function improvement, and on the HOS Sports, MCID was achieved by 65% 
      whereas 43% met the SCB criteria. CONCLUSIONS: MCID values ranged from 7.9 on the 
      mHHS and the HOS ADL to 13.1 on the HOS Sports. SCB net change ranged from 16.2 
      on the HOS ADL to 25.2 on the iHOT-33, whereas absolute SCB ranged from 82.4 on 
      the iHOT-33 to 84.7 on the mHHS. Residual FAI and capsular management were the 
      most common indications for revision surgery with patients who underwent surgery 
      for the former found to be most likely to achieve clinically significant 
      improvement. LEVEL OF EVIDENCE: Level IV, case series.
