Lateral epicondylitis (LE), commonly referred to as “tennis elbow,” is a common condition of the extensor tendons of the forearm that can lead to pain along the lateral epicondyle with radiation into the forearm, decreased grip strength, and difficulty lifting objects. When LE symptoms progress and can no longer be managed with non-operative measures, LE debridement may be indicated. The approach presented here is an open debridement of the extensor carpi radialis brevis (ECRB) tendon origin. A 3–4-cm longitudinal incision was placed longitudinally over the lateral epicondyle, radial head, and capitellum. The ECRB was exposed then debrided, the lateral epicondyle was decorticated, the lateral collateral ligament was repaired, the wound was closed in layers, and a soft dressing and splint were placed.
