Rotator cuff repair in patients with rheumatoid arthritis.

BACKGROUND: Currently, there is very little information available regarding the results of rotator cuff repair in patients with rheumatoid arthritis. Therefore, we reviewed our experience to determine the results, the risk factors for an unsatisfactory outcome, and the rates of failure of this procedure. METHODS: We retrospectively reviewed the records of all patients with rheumatoid arthritis who had undergone repair of a rotator cuff tear at our institution from 1988 to 2002. Twenty-three shoulders in twenty-one patients were identified. The median duration of follow-up for the twenty shoulders that did not require revision surgery was 9.7 years. Nine shoulders had a partial-thickness tear, and fourteen had a full-thickness tear. The shoulders were assessed with regard to pain, functional outcome, and overall patient satisfaction. RESULTS: Patients with both partial and full-thickness rotator cuff tears had significant improvements in terms of overall pain (p < 0.05) and satisfaction (p < 0.05). Patients who had undergone repair of a partial-thickness tear had improved active elevation (from 155 degrees to 180 degrees; p = 0.03), whereas patients who had undergone repair of a full-thickness tear did not have improved elevation. Six of the fourteen shoulders with a full-thickness tear had an unsatisfactory result, whereas only two of the nine shoulders with a partial-thickness tear had an unsatisfactory result. CONCLUSIONS: Rotator cuff repair in patients with rheumatoid arthritis can be challenging. However, durable pain relief and patient satisfaction can be achieved. Functional gains should not be expected in patients with full-thickness rotator cuff tears. Repair of the rotator cuff in patients with rheumatoid arthritis can be undertaken when nonoperative measures for pain relief have failed.
