Psychometric Analysis Of The Oxford Shoulder Score For Use In Evaluating Outcomes From Primary Shoulder Replacement Surgery

Purpose: The Oxford Shoulder Score (OSS) is a shoulder-specific patient-reported outcome measure (PROM) that is designed to measure patient-reported pain and function after shoulder surgery. While the reliability, validity, responsiveness, and minimal clinically important change (MCIC) of the OSS has been examined in selected patient cohorts, this research has not been undertaken in people undergoing primary total shoulder replacement (TSR). This project aimed to investigate the psychometric properties and estimate the MCIC for the OSS in patients undergoing TSR.
