Comparisons of outcomes after rotator cuff repair between Worker’s Compensation Board (WCB) recipients and nonrecipients generally
do not consider patient, injury, and shoulder characteristics. We compared preoperative differences between WCB recipients
and nonrecipients and determined the impact on their 6-month postoperative outcome. We evaluated a prospective cohort of 141
patients with full-thickness rotator cuff tears, 36 of whom (26%) were WCB recipients, preoperatively and 3 and 6 months after
rotator cuff repair. Their mean age was 54.0 ± 10.4 years (standard deviation) and 102 (72%) patients were male. Shoulder
range of motion, Western Ontario Rotator Cuff (WORC) index, and American Shoulder and Elbow Surgeons’ score were used to evaluate
outcomes. We performed regression analyses to control for baseline differences in age, baseline scores, smoking status, symptom
duration, injury type, and associated biceps disorder between WCB recipients and nonrecipients. WCB recipients were younger
and more likely to smoke, have a traumatic injury, and undergo surgery within 6 months of injury. WCB recipients had lower
recovery for all outcomes when these differences were not considered but when differences were accounted for, only 6-month
WORC scores were lower in WCB recipients. Clinicians should consider preoperative characteristics before concluding WCB recipients
experience less recovery after surgical repair.
