This study determined the minimal clinically important difference (MCID) for three shoulder outcome measures after arthroplasty. Using an anchor-based method in 326 patients, it defined the smallest score change that patients perceive as clinically meaningful. It covers the ASES score, Simple Shoulder Test, and VAS pain score.
When you read a shoulder arthroplasty outcomes paper and see a statistically significant improvement, the real question is whether the patient actually felt it. This study gives you the yardstick. Memorize the three thresholds: 21 points for ASES, 2.4 for SST, 1.4 for VAS pain. Any improvement below these numbers may be statistically real but clinically meaningless to the patient.
The anchor-based method matters here. It ties the score change to a patient's own rating of whether treatment worked, which is more clinically grounded than distribution-based statistics.
A practical takeaway: these MCIDs apply equally to anatomic and reverse TSA, and they mirror the nonoperative rotator cuff values. That consistency lets you use these thresholds broadly when appraising shoulder literature.
