Arthroscopic capsular release of flexion contractures (arthrofibrosis) of the elbow.

Twelve patients with flexion contractures of the elbow were managed by arthroscopic release of the proximal capsule and debridement of the olecranon fossa. Postoperatively the mean flexion contracture improved from 38 to 3 degrees with supination improving from 45 to 84 degrees and pronation improving from 80 to 88 degrees. All patients reported a decrease in pain level as well as improvement in motion. There was one severe complication in this series, in which a patient sustained a permanent posterior interosseous nerve palsy. Arthroscopic limited capsular release appears to be satisfactory management modality for flexion contracture of the elbow.
