Core Tip

Core Tip: In this study, we present a new approach for analyzing and interpreting improvement in patient-reported outcome measures (PROM) scores by linking the improvement in PROM scores to the minimal clinical difference for each patient. We found that approximately 90% of patients treated with an anatomical total shoulder arthroplasty for glenohumeral osteoarthritis had a clinically relevant improvement two years postoperatively.
