Aims. Lateral epicondylitis is a frequent pathology usually resolved with conservative methods but ocasionally evolve to chronic unresolved tendinosis. Bipolar Radiofrequency has potentially the effect to stimulate a healing response on chronic tendinosis. We present the results of 15 cases with chronic epicondylitis treated with Bipolar Radiofrequency.

Methods. Fifteen patients with chronically lateral epicondylitis and previously failed conservative treatment during 6 months with antiinflamatory drugs, phisiotherapy and at least 3 corticosteroid injections were treated with open Bipolar Radiofrequency. Using local anesthesia, and through a 2 cm incision the tendon was stimulated using the TOPAZ ward (Arthrocare,CA). It was done at 5 mm. distance intervals in a clock-wise fashion in the symptomatic area. The incision was closed with 2 sutures and a compressive bandage was applied. No movement was restricted and rehabilitation began immediately.

Results. After an average follow-up of 18 months (6–24), results were excellent in 14 cases and good in one case. The postoperative VAS scores were decreased by 60% at 7 days postoperative, 80% at three weeks and 95% at 6 months. Return to job was at an average of 3 weeks (15 days–4 weeks). All patients were satisfied with the result.

Conclusions. Bipolar Radiofrequency is an alternative, effective and safe method for treatment of chronic lateral epicondylitis when conservative treatments are not effective.
