AB  - BACKGROUND: Preoperative and postoperative patient self-reported measures are the 
      key to understanding the benefit of shoulder arthroplasty for patients with 
      different diagnoses and having different surgical approaches. The minimal 
      clinically important difference (MCID) for patient-reported outcomes such as the 
      Simple Shoulder Test (SST) is often used to document the amount of improvement 
      that is of importance to the patient; however, the MCID may differ for different 
      types of shoulder arthroplasty. The objective of this study was to report the 
      MCID of the SST and the MCID of the percentage of maximal possible improvement 
      (%MPI) for 5 different arthroplasty types. METHODS: Eight hundred eighty-seven 
      patients undergoing shoulder arthroplasty with preoperative SST scores, 2-year 
      postoperative SST scores, and patient satisfaction were included. The sample 
      comprised 368 patients undergoing anatomic total shoulder arthroplasty (aTSA), 
      330 patients undergoing ream-and-run arthroplasty (R&R), 80 patients undergoing 
      reverse total shoulder arthroplasty (rTSA), 53 patients undergoing cuff tear 
      arthropathy arthroplasty, and 56 patients undergoing hemiarthroplasty. For each 
      type of arthroplasty, the anchor-based method was used for calculating the MCID 
      for both absolute SST scores and %MPI. RESULTS: Significant improvements in SST 
      values were seen for all arthroplasty types. The MCID for SST change was 2.3 
      overall but ranged from 1.6 for aTSA, to 2.6 for R&R, to 3.7 for rTSA. The MCID 
      for %MPI was 32% overall but ranged from 22% for aTSA to 42% for 
      hemiarthroplasty. The percentage of patients exceeding the MCID threshold was 
      highest for aTSA at 96% and lowest for hemiarthroplasty at 61%. CONCLUSION: The 
      same MCID value may not be appropriate for different types of shoulder 
      arthroplasty. This study reports MCID thresholds that can be used when assessing 
      the effectiveness for each of the common types of shoulder arthroplasty.
