Strong correlation of the Patient-Reported Outcomes Measurement Information System (PROMIS) upper extremity and Shoulder Arthroplasty Smart (SAS) score to legacy measures in shoulder arthroplasty patients

The present study suggests PROMIS UE and SAS are effective, shoulder-specific alternatives to legacy instruments. Both instruments showed strong, increasing correlations with ASES through 2 years follow-up and demonstrated low ceiling effects, indicating sensitivity across a broad functional range. These results highlight the clinical utility of PROMIS UE and SAS for patient-centered outcome assessment in shoulder arthroplasty populations.
