Elbow medial ulnar collateral ligament reconstruction: clinical relevance and the docking technique

Abstract

Introduction: Elbow ulnar collateral ligament (UCL) reconstruction has become the standard of care for the throwing athlete with a symptomatic ruptured or insufficient ligament and the desire to resume competitive play. Since Jobe's initial description of UCL reconstruction, the technique has evolved. A novel modification was the "docking" technique developed by Altchek. Subsequently, the docking technique as originally described was slightly modified. Arthroscopy is no longer routinely performed, and in some cases, a 3-strand graft is used.

Materials and methods: We treated 21 overhand athletes with clinical and radiographic evidence of UCL insufficiency with ligament reconstruction using a modified version of the docking technique using a 3-strand graft. There were 5 professional, 11 college, and 5 high school baseball players in the reconstructed group. Athletes were evaluated postoperatively by use of the Conway Scale.

Results: Of the 21 patients who underwent the modified docking technique with a three-strand graft, 19 (90%) had excellent results. There were 2 good results and no complications.

Discussion: UCL reconstruction can successfully treat athletes with UCL insufficiency. Several different reconstruction techniques have been described. By use of the docking and modified docking techniques, good to excellent results can be achieved in the majority of cases with a low complication rate.
