Elbow arthroscopy is a technically demanding procedure but it is very useful to evaluate the entire elbow joint for pathology with minimal surgical exposure and faster recovery than a traditional arthrotomy. The neurovascular structures of the elbow joint are in close proximity to the joint, thus there is a risk of injury to these structures, so care must be taken to fully understand elbow anatomy and to be prepared for aberrations. Elbow arthroscopy can be used diagnostically, as in this video article, or to surgically treat a variety of conditions including ligamentous tears, loose bodies, capsular stiffness, osteochondritis dissecans of the elbow, osteophyte debridement, and lateral epicondylitis. A patient with a previous ulnar nerve transposition is a relative contraindication to elbow arthroscopy, as there is a high risk of injury to the ulnar nerve during portal placement.
