Osteoarthritis of the elbow: results of arthroscopic osteophyte resection and capsulectomy.

Primary osteoarthritis of the elbow involves formation of bony spurs, loose bodies, and capsular contracture. This article presents the results of an arthroscopic technique for treatment of elbow arthritis in a series of patients. A retrospective chart review identified 41 patients with primary osteoarthritis in 42 elbows who underwent arthroscopic osteophyte resection and capsulectomy and who had more than 2 years of follow-up. Preoperative motion, pain, and Mayo Elbow Performance Index scores were compared with those at the latest follow-up. At an average follow-up of 176.3 weeks, significant improvements occurred in mean flexion, from 117.3 degrees preoperatively to 131.6 degrees (P < .0001); extension, from 21.4 degrees to 8.4 degrees (P < .0001); supination, from 70.7 degrees to 78.6 degrees (P = .0056); and Mayo Elbow Performance Index scores (P < .0001), with 81% good to excellent results. Pain decreased significantly (P < .0001). Complications were rare (n = 2) and included heterotopic ossification and ulnar dysesthesias. This procedure addresses the pathologic processes associated with arthritis of the elbow and was safe and effective in this series.
