[Arthroscopic treatment of tennis elbow: preliminary experience with 14 patients]

The purpose of the study was to report our experience in a preliminary series of patients who underwent arthroscopic treatment of tennis elbow in order to appreciate effectiveness of this method. Between September 2000 and February 2004, we treated arthroscopically fourteen patients with epicondylitis which failed to respond to medical treatment given for a mean duration of 15.8 months. We used the technique described by Baker in 1999. Briefly, the external capsule was sectioned followed by section of the extensor carpi radialis brevis and extensor digitorum communis insertions on the epicondyle. Section was continued until muscle fibers were visible. Mean patient age was 45 years (range 36-55). Five patients were victims of occupational accidents and one had an occupational disease. One patient suffered from fibromyalgia. All patients were reviewed at a mean follow-up of 11.5 months. We used the Mayo Clinic score to assess outcome which was excellent or good in nine patients, fair in one and poor in four. Despite these modest preliminary results, arthroscopy appears to be well indicated for this pathological condition. The ideal treatment remains a question of discussion.
