Background: Thumb ulnar collateral ligament (UCL) tears are common in competitive athletes. These tears often occur as a result of a radially directed force on an extended thumb. To date, no literature exists on the use of suture tape augmentation for repair of the thumb UCL in a competitive athlete cohort.
Hypothesis: Using suture tape augmentation for the thumb UCL will allow for a safe and expedient return to play in competitive athletes.
Study design: Case series; Level of evidence, 4.
Methods: A retrospective chart review was completed to identify all patients who underwent operative primary thumb UCL repair between 2014 and 2018. All procedures were performed at a single institution by the senior author. Inclusion criteria were acute complete tears of the thumb metacarpophalangeal joint UCL, treated with primary repair via suture tape augmentation in competitive high school, collegiate, or professional athletes. Exclusion criteria included recreational athletes, patients who underwent reconstruction (rather than repair), and patients with insufficient follow-up to establish return to play. Charts of patients identified through the retrospective review were further evaluated to determine patient- and injury-related variables. Return to play was defined as return to game competition and stratified as to whether this was at the same level of competition or any level of competition.
Results: A total of 18 thumbs in 17 competitive high school, collegiate, and professional athletes were included in this study. One of the professional basketball players sustained injury to both thumbs approximately 10 months apart. The study group comprised 4 collegiate baseball players, 6 professional baseball players, 3 professional basketball players, 1 professional hockey player, 1 amateur-level hockey player, 1 high school basketball player, and 1 high school volleyball player. Mean follow-up was 27.9 months, and no complications were noted. Athletes who sustained an in-season injury (n = 13; 72.2%) returned to play at any level at a mean ± SD of 30.9 ± 10.1 days and at the same level at 36.3 ± 11.2 days. Athletes who sustained an out-of-season injury (n = 5; 27.8%) returned to play at any level at 101.4 ± 86.6 days and at the same level at 114.6 ± 87.0 days.
Conclusion: The findings presented here offer evidence for return to play in competitive high school, collegiate, and professional athletes with a thumb UCL tear treated with repair and suture tape augmentation. All athletes returned to the same level of play. Those attempting to return in-season returned to the same level of play at a mean of just under 5 weeks. Augmenting the repair with anchored suture may prevent prolonged immobilization, expedite thumb motion, and improve postoperative recovery.
