Update on Performance and Return to Sport After Biceps Tenodesis in Professional Baseball Players.

Background: Bicipital disorders are common among overhead athletes, especially professional baseball players. The ideal treatment for bicipital problems in professional baseball players is unknown.

Purpose/hypothesis: The purpose was to determine the return-to-sport (RTS) rate and performance after RTS in professional baseball players who underwent biceps tenodesis. It was hypothesized that there will be a high RTS rate in this population, with no difference between the biceps tenodesis and control groups in the RTS rate or performance.

Study Design: Case series; Level of evidence, 4.

Methods: All professional Major League Baseball players who underwent biceps tenodesis between 2014 and 2017 were included. Players with concomitant rotator cuff repair were excluded. Demographic and performance data (preoperative and postoperative) were recorded for each player. Performance metrics were then compared between players with biceps tenodesis and matched controls (no history of biceps tenodesis).

Results: Included were 14 players (mean age, 27 ± 4 years; 12 pitchers, 2 position outfielders). Most surgeries (79%) were open subpectoral tenodeses, 2 were arthroscopic biceps transfers, and 1 was an arthroscopic suprapectoral tenodesis. Fixation methods included cortical button (42%), interference screw (25%), suture anchor (25%), and drill holes (8%). Most players (79%) underwent concomitant procedures (43% underwent superior labral anterior-posterior repairs). While 86% (12/14) were able to RTS, 50% (7/14) returned at the same or a higher level, and 50% of the whole study were either unable to return or returned to a lower level. Among pitchers, 100% (12/12) were able to RTS, but only 50% (6/12) were able to return to the same or a higher level. For those players who did RTS, it took 245 ± 84 days, and their performance after RTS was unchanged and did not differ from that of matched controls.

Conclusion: Open subpectoral tenodesis was the most common tenodesis technique performed on professional baseball players. While 86% of players returned to sport after biceps tenodesis, only 50% returned to the same or higher level. No decline in performance was noted in players who returned successfully.
