AB  - BACKGROUND: The minimal clinically important difference (MCID) is the threshold 
      value for a change that would be considered meaningful by the patient. The 
      purpose of this study was to determine the MCIDs for the Rowe score and the 
      Western Ontario Shoulder Instability Index (WOSI) score after arthroscopic repair 
      of anterior shoulder instability. METHODS: The study enrolled 198 patients who 
      underwent an arthroscopic stabilization procedure for anterior shoulder 
      instability. Patients were assigned to no change and minimal change groups by a 
      15-item questionnaire at the 1-year postoperative visit. The Rowe and WOSI scores 
      were assessed preoperatively and at a 1-year postoperative follow-up. The MCID 
      was calculated using an anchor-based method and a distribution-based method. 
      RESULTS: There were 9 patients in the no change group and 26 patients in the 
      minimal change group. The MCID for the Rowe score was 9.7 according to the 
      anchor-based method. By the anchor-based method, the authors could not calculate 
      MCID for the WOSI score because of insignificant difference of the mean score 
      changes between the no change and minimal change groups. By the 
      distribution-based method, MCIDs for the Rowe and the WOSI scores were 5.6 and 
      151.9 with the standard deviation-based estimate and 2.2 and 60.7 with the effect 
      size-based estimate, respectively. CONCLUSIONS: To assess the effectiveness of an 
      arthroscopic stabilization procedure for anterior shoulder instability using the 
      Rowe score, a difference of at least 9.7 in the score is clinically relevant. To 
      compare clinical outcomes between different modalities, we should consider not 
      only statistically significant differences but also the MCID.
