AB  - BACKGROUND: Open repair for gluteus medius and minimus tears is a common surgical 
      treatment for patients with lateral hip pain associated with abductor tears; 
      however, clinically meaningful outcomes have not been described after open 
      surgical treatment. PURPOSE: To define the minimal clinically important 
      difference (MCID) in patient-reported outcome measures (PROMs) in patients 
      undergoing open gluteus medius or minimus repair, and to identify preoperative 
      patient characteristics predictive of achieving MCID postoperatively. STUDY 
      DESIGN: Case series; Level of evidence, 4. METHODS: A retrospective review of 
      prospectively collected data from a consecutive series of patients undergoing 
      open abductor repair between July 2010 and April 2019 was conducted. 
      Perioperative patient data collected included patient characteristics and 
      preoperative and postoperative modified Harris Hip Score (mHHS) and International 
      Hip Outcome Tool (iHOT-33) score. Paired t tests were utilized to compare 
      preoperative and postoperative PROMs and MCID was calculated for both PROMs. 
      Multivariate logistical regression analysis was used to assess the association 
      between preoperative variables and the likelihood for achieving MCID. RESULTS: A 
      total of 47 patients were included in the study. The majority of patients were 
      female (78.7%), with an average age of 63 +/- 10.7 years. The average follow-up for 
      both the mHHS and the iHOT-33 surveys was 37.8 +/- 27.9 months (range, 10-102 
      months). Patients demonstrated statistically significant improvements on the mHHS 
      and iHOT-33 postoperatively (P < .001 for both). The MCIDs of mHHS and iHOT-33 
      were calculated to be 9.9 and 14.3, respectively. Overall, 82.9% of patients 
      achieved MCID for mHHS and 84.1% of patients achieved MCID for iHOT-33 
      postoperatively. Multivariate logistical analysis demonstrated younger patients 
      were less likely to achieve MCID for both outcome measures. Four patients (8.5%) 
      suffered postoperative complications after open repair. CONCLUSION: This study 
      defined MCID for mHHS and iHOT-33 for patients undergoing open repair of hip 
      abductor tears, with a large percentage of patients (>80%) achieving meaningful 
      outcomes for both outcome measures. There was a low complication rate. Younger 
      patients were less likely to achieve MCID compared with older patients.
