[Arthroscopic debridement of the extensor carpi radialis brevis]

Surgical treatment of lateral epicondylitis is reserved for patients who, despite extensive conservative therapy, do not experience satisfactory relief of symptoms. As an alternative to the open procedure, arthroscopic debridement of the extensor carpi radialis brevis (ECRB) muscle is a simple and standardized procedure. The arthroscopic approach also enables the additional treatment of intra-articular pathologies such as loose bodies or osteochondral lesions. After diagnostic arthroscopy, the attachment of the ECRB is visualized via the anteromedial portal, so that under visual control the debridement of the tendon fibers of the ECRB and its bony insertion site can be performed via the anterolateral portal. Postoperatively, there is no restriction of movement of the elbow joint. The outcome after arthroscopic ECRB debridement described in the literature is equivalent to that of other surgical techniques.
