Background: Psychological distress has been associated with declining shoulder function in patients with rotator cuff tears (RCTs). Thus, we aimed to 1) evaluate the absence or presence of differences in shoulder pain, function, or pain-associated psychological distress in patients with increasing RCT severity and 2) assess whether psychological distress is associated with shoulder pain and function while adjusting for RCT severity. Methods: Consecutive patients who underwent rotator cuff repair and completed the optimal screening for prediction of referral and outcome (OSPRO) survey from 2019 to 2021 were included. OSPRO is composed of 3 domains that estimate pain associated psychological distress (negative mood, negative coping, and positive coping). Demographics, tear characteristics, and three patient reported outcomes (PRO), including the visual analog scale (VAS), Single Assessment Numeric Evaluation, and American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES) were collected. Patients were analyzed with analysis of variance and chi-square tests and stratified based on severity of RCTs into three groups: partial-thickness, small-to-medium full-thickness, and large-to-massive full-thickness tear. Linear regression analysis was used to evaluate the association between OSPRO scores and PROs, adjusting for severity of RCT. Results: Eighty-four patients were included: 33 (39%) had partial-thickness, 17 (20%) had small-to-medium full-thickness, and 34 (41%) had large-to-massive tears. Regarding PROs and psychological distress, there were no significant differences amongst the three cohorts. In contrast, multiple significant associations between psychological distress and PROs were found. Within the negative coping domain, fear avoidance dimensions demonstrated the strongest correlation to PROs: fear-avoidance behavior for physical activity (ASES Beta −0.592, P < .001; VAS 0.357, P < .001) and work (ASES Beta −0.442, P < .001; VAS 0.274, P = .015). Several other dimensions within the negative coping, negative mood, and positive coping domains also demonstrated significant associations to PROs. Discussion: These findings suggest that in patients undergoing arthroscopic rotator cuff repair, preoperative psychological distress can more strongly influence patient perception of shoulder pain and diminished shoulder function than RCT severity.
