Fig 2.

(A) When viewing the medial aspect of this left elbow, once the capsule and native ulnar collateral ligament have been split longitudinally, the ulnohumeral (UH) joint is easily visualized. The 2 ulnar tunnels are anterior and posterior to the sublime tubercle and coalesce at their bases. (B) Proximally, the humeral socket is created at the origin of the ulnar collateral ligament at the anterior-inferior aspect of the medial epicondyle (ME). (C) Two 1.5-mm sockets are created proximally that connect to the base of the 4.5-mm socket. Sutures are later retrieved through these sockets to dock the graft in the 4.5-mm socket.
