Abstract
Introduction
Anterolateral procedures can reduce the risk of re-rupture after ACL reconstruction in high risk patients however, this effectiveness has never been evaluated in elite athletes. The purpose of this study was to evaluate the effectiveness of lateral extra-articular tenodesis in reducing revision rates in ACL reconstructions in elite athletes.
Methodology
A consecutive cohort of elite athletes between 2005 and 2018 undergoing ACLR reconstruction with or without modified Lemaire lateral extra-articular tenodesis were analysed. A minimum of 2 years of follow-up was required. The association between the use of LET and ACL graft failure was evaluated with univariate and multivariate logistic regression models.
Results
455 elite athletes (83% male; 22.5±4.7 years) underwent primary ACL reconstruction with (n=117) or without (n=338) a LET procedure. Overall, 36 athletes (7.9%) experienced ACL graft failure including 32 (9.5%) reconstructions without a LET and 4 (3.4%) with a LET. Utilization of LET during primary ACL reconstruction reduced the risk of graft failure by 2.8 times with 16.5 athletes needing to be treated with LET to prevent a single ACL graft failure. Multivariate models showed that LET significantly reduced the risk of graft rupture (RR=0.325; p=.029) as compared to ACL reconstruction alone after controlling for age at ACL reconstruction and gender. Including graft type in the model did not significantly change the risk profile.
Conclusion
The addition of LET in elite athletes undergoing primary ACL reconstruction reduced the risk of undergoing revision by 2.8 times.
