Increased chance of ACL rupture found among collegiate athletes with slower stabilization time

Results from this case-control study demonstrated an increased chance of ACL rupture among collegiate athletes with slower backward time to stabilization at baseline.
Researchers included 278 National Collegiate Athletic Association Division I athletes who participated in high-risk sports for ACL injury. Investigators collect data from baseline time to stabilization for backward, forward, medial and lateral single-legged landing tasks. During a period of 4 years, athletes were followed and the incidence of ACL rupture was noted. Differences in time to stabilization for each jump landing task between athletes with ACL ruptures and those without ruptures were evaluated using independent t tests. Investigators also used logistic regression models to determine whether time to stabilization was a predictor for ACL rupture.
Results showed nine athletes had noncontact ACL ruptures and compared with uninjured athletes, those athletes took longer to stabilize during the baseline backward jump landing. Investigators noted a comparison of injured and uninjured athletes showed a three-fold increase in the odds of ACL rupture for every 1-second increase in the backward time to stabilization. ‒ by Monica Jaramillo
