Podium Presentation Title: Increasing Shoulder Osteoarthritis Severity Score Predicts Lower Patient-Reported Outcomes Measurement Information System-Upper Extremity (PROMIS-UE) Score After Cuff Repair

Mild to moderate glenohumeral osteoarthritis (GHOA) is a common finding among patients who are evaluated for rotator cuff (RC) tears. However, the impact of pre-operative shoulder joint degeneration on patient-reported outcomes (PROs) following RC repair (RCR) not well-established. Certain studies have reported negative association between radiographic findings and RCR PROs, while other found no substantial association. The purpose this study apply MRI-based Shoulder Osteoarthritis Severity (SOAS) score evaluation undergoing determine relationship pathology present MRI with post-operative PROMIS-UE scores. Seventy-one MRIs corresponding 71 were analyzed by two independent reviewers scored using SOAS criteria. Intraclass correlation coefficients calculated total as well each sub-score. Spearman’s correlations averaged scores, patient demographics, Linear regression analysis was performed variables age, sex, BMI, significant components determined univariate dependent variable score. All statistical STATA. Significance defined p<0.05. mean cohort 51.5 ± 7.5, average 21.5 8.4. coefficient (ICC) 0.63. There increasing worsening (r = -0.24, p 0.04). Both cartilage wear -0.33, 0.0045) AC 0.048) individually demonstrated an predictor in multiple linear BMI (β -1.05, 0.038). In RCR, predictive lower sub-scores strongest scores included degeneration. Cartilage subscore negatively correlated demographic factors multivariate analysis.
