Abstract

Background: Optimal patient selection is key to success of operative treatment for cuff tears. We assessed predictors of pain and functional outcomes in a longitudinal cohort of patients undergoing operative treatment. Methods: From March 2011 to January 2015, a cohort of patients with rotator cuff tears undergoing rotator cuff surgery was recruited. Patients completed a detailed health and demographic questionnaire, standardized shoulder questionnaires, including the Shoulder Pain and Disability Index (SPADI), and underwent a magnetic resonance imaging scan. Patients received follow-up questionnaires at 3, 6, 12, and 18 months. We assessed longitudinal predictors of SPADI using longitudinal mixed models. Interactions with follow-up duration after surgery were also assessed. Results: In our analysis (n = 50), a lower Fear-Avoidance Beliefs Questionnaire physical activity score (P =.001) predicted a lower SPADI score (better shoulder pain and function). Those consuming alcohol 1 to 2 times per week or more had lower SPADI scores than those consuming alcohol 2 to 3 times per month or less (P =.017). Both of these variables had a significant interaction with duration of follow-up. Variables that were not significant predictors of SPADI included sociodemographic characteristics, magnetic resonance imaging characteristics, such as tear size and muscle quality, shoulder strength, and variations in surgical techniques/performance of adjuvant surgical procedures. Conclusions: Those with higher fear avoidance behavior and alcohol use of 1 to 2 times per week had worse shoulder pain and function at 18 months of follow-up. These data can be used to select optimal candidates for operative treatment of rotator cuff tears and assist with patient education and expectations before treatment.
