Do outcomes differ after rotator cuff repair for patients receiving workers' compensation?

Area of Science:

• Orthopedic Surgery
• Rehabilitation Medicine
• Health Services Research

Background:

• Rotator cuff repair outcomes are often compared between Worker's Compensation Board (WCB) recipients and nonrecipients.
• Previous comparisons often overlook crucial patient, injury, and shoulder characteristics.
• Understanding these differences is vital for accurate outcome assessment.

Purpose of the Study:

• To compare preoperative differences between WCB recipients and nonrecipients.
• To determine the impact of these differences on 6-month postoperative outcomes after rotator cuff repair.

Main Methods:

• Prospective cohort study of 141 patients with full-thickness rotator cuff tears.
• Evaluated outcomes using shoulder range of motion, Western Ontario Rotator Cuff (WORC) index, and American Shoulder and Elbow Surgeons' (ASES) score.
• Regression analyses controlled for baseline differences in age, smoking status, injury type, and symptom duration.

Main Results:

• WCB recipients were younger, more likely to smoke, had traumatic injuries, and underwent surgery sooner.
• Unadjusted outcomes showed lower recovery for WCB recipients across all measures.
• After adjusting for baseline characteristics, only 6-month WORC scores remained significantly lower for WCB recipients.

Conclusions:

• Initial comparisons may overestimate the negative impact of WCB status on rotator cuff repair outcomes.
• Preoperative patient and injury characteristics significantly influence postoperative recovery.
• Clinicians should consider these factors before concluding WCB recipients experience less recovery.
