Arthroscopic release of the stiff elbow.

Treatment of the stiff elbow by arthroscopic capsular release is a relatively new and effective procedure. The surgery is technically demanding and is not indicated in all cases of stiff elbow. Although neurologic complications are unusual, they can be severe and permanent. Neurologic structures at particular risk are the posterior interosseous and ulnar nerves. Rehabilitation is as important as the surgical procedure itself. Arthroscopic capsular release is particularly effective in elbows with minor flexion contractures (less than 30 degrees) and might have some advantages over an open procedure for these minor contractures.
