SummaryMany different surgical options are available for the treatment of lateral epicondylitis. One of the most simple involves a release that can be performed in the office or an outpatient surgery center. This procedure involves infiltration of local anesthesia at the point of origin of the extensor carpi radialis brevis. A number 11 knife blade is used to release the extensor carpi radialis brevis from the epicondyle. Soft dressings are applied, and the patient is allowed immediate range of motion. Normal activities usually are resumed approximately 3 weeks to 3 months after surgery. In a review of 21 elbow operations in 17 patients who underwent a percutaneous release, 20 of 21 elbows resumed normal function and had an Andrews-Carson rating of approximately 198/200. One patient had failed percutaneous release and required reoperation. For isolated lateral epicondylitis, a percutaneous release performed in the office is an effective treatment for recalcitrant lateral epicondylitis that has failed nonoperative management.
