This study set out to define what change in the ASES score actually matters to patients after shoulder arthroplasty. Prior MCID values came from mixed or nonoperative populations, not arthroplasty patients. Using a registry of 490 patients, the authors calculated the MCID and SCB for both anatomic and reverse shoulder replacement.
When you report that a shoulder arthroplasty patient's ASES score improved, this paper tells you which numbers actually mean something. A 9-point gain crosses the MCID (clinically important), and a 23-point gain reaches substantial clinical benefit. Statistically significant is not the same as clinically meaningful.
The practical counseling pearl: patients who walk in with high preoperative ASES scores are less likely to reach these thresholds because there is less room to improve. Manage expectations before surgery. Because MCID and SCB were the same for anatomic and reverse replacements, you can apply one set of thresholds across both when reading outcome studies.
Weigh the evidence carefully. This is a single-institution, Level III retrospective cohort with 39% loss to followup, so treat the values as reasonable benchmarks rather than absolute cutoffs.
