Lateral epicondylitis is the most common affliction of the elbow. When conservative measures fail, surgical treatment is typically directed at excision or debridement of the pathologic origin of the extensor carpi radialis brevis at its humeral origin. This is traditionally carried out through an open approach. With a better understanding of the anatomy of the tendon and ligamentous origins at the lateral epicondyle, arthroscopic methods for the surgical treatment of lateral epicondylitis have been developed. This review covers the anatomy of the extensor tendon origins with an arthroscopic technique based on anatomical dissections that can be used to surgically treat lateral epicondylitis. Surgical pearls and early clinical results are presented.
