The History and Evolution of Elbow Medial Ulnar Collateral Ligament Reconstruction: from Tommy John to 2020.

PURPOSE OF REVIEW: The purpose of this review article is to discuss the evolution of surgical reconstruction of the anterior bundle of the UCL, otherwise known as Tommy John surgery, from Dr. Jobe's initial description in 1986 to present day. In particular, the unique changes brought forth by each new surgical technique, and the reasons that these changes were implemented, are highlighted. RECENT
FINDINGS: The incidence of UCL reconstruction surgery continues to increase significantly, particularly in the 15- to 19-year-old age group. New anatomic understanding of the anterior bundle of the UCL, including the importance of the central fibers and the broad and tapered ulnar insertion, may affect optimal UCL reconstruction techniques in the future. Although return to play rates are generally quite high (80-95%), the mean time to return to play (typically 12-18 months for pitchers) is longer than desired. Accordingly, many authors feel that there remains room for improvement in the treatment of this common injury. The Tommy John surgery has evolved in many ways with the development of novel techniques over the last 35 years. Currently, overhead throwing athletes undergoing UCL reconstruction have high return to play and low complication rates. Future modifications to the surgery may aim to further improve outcomes and, more importantly, expedite the length of postoperative rehabilitation.
