AB  - BACKGROUND: The aim of this study was to define the minimal clinically important 
      difference (MCID) values for patient-reported outcomes (PROs) after arthroscopic 
      treatment of snapping scapula syndrome (SSS) using a distribution-based method, 
      and to identify demographic, clinical, and intraoperative factors significantly 
      associated with the achievement of MCID. It was hypothesized that subjective 
      satisfaction scores after the procedure would be strongly associated with the 
      achievement of MCID thresholds for the PROs and that pain, preoperative response 
      to injection, and a scapulectomy in addition to bursal resection would be 
      predictive of clinically relevant improvement. METHODS: Patients who underwent 
      arthroscopic treatment of SSS between October 2005 and September 2020 with a 
      minimum of 2-year short-term postoperative follow-up were enrolled in this 
      retrospective single-center study. The MCID was calculated using a 
      distribution-based approach for the following PROs: 12-Item Short Form Health 
      Survey (SF-12), American Shoulder and Elbow Surgeons Standardized Shoulder 
      Assessment Form (ASES), Quick Disabilities of the Arm, Shoulder, and Hand 
      questionnaire (QuickDASH), Single Assessment Numeric Evaluation (SANE), and 
      visual analog scale (VAS) pain "today" and "at worst." The association between 
      achievement of the MCID and postoperative subjective satisfaction was 
      investigated, and factors associated with achievement of MCID were determined 
      using bivariate analysis. RESULTS: Of a total of 190 patients assessed for 
      eligibility, 77 patients (38.1 +/- 14.3 years; 36 females) were included. Within 
      the study population, statistically significant improvements in postoperative 
      SF-12 physical component summary (PCS) (P < .001) and mental component summary 
      (MCS) (P < 0.034), ASES (P < .001), QuickDASH (P < .001), SANE (P < .001), and 
      VAS pain (P < .001) scores were observed at the minimum 2-year follow-up. The 
      calculated MCID threshold values based on the study population were 5.0 for SF-12 
      PCS, 5.8 for SF-12 MCS, 11.3 for ASES, -10.5 for QuickDASH, 14.7 for SANE, 1.5 
      for VAS pain, and 1.7 for VAS pain at worst. Reaching the MCID was strongly 
      associated with postoperative satisfaction (rated on a scale of 1-10). Across the 
      PROs, younger age, favorable preoperative response to injection, partial 
      scapuloplasty or scapulectomy, no prior surgery, and pain and function at 
      baseline were significantly associated with attaining MCID. CONCLUSIONS: Patients 
      who underwent arthroscopic treatment for SSS experienced clinically significant 
      improvements in functional scores, pain, and quality of life. This study 
      demonstrated predictive roles for certain patient-specific factors and diagnostic 
      variables for achieving MCID in PROs, which may help surgeons preoperatively 
      assess the probability of success and manage patient expectations.
