Does Fatigue Influence ACL Injury Risk?


This question is a nice topic of debate between researchers & clinicians.


A recent review by Bourne et al (2019) showed that there is no current evidence to suggest that there is a link; however Benjaminse et al (2019) recommend that we train our athletes to resist fatigue to reduce ACL injury risk.


Whatever side of the fence you sit on however; van Melick et al (2019) showed in a group of ACLR soccer players that fatigue significantly affected movement quality (as per Landing Error Scoring System - LESS) as compared to a group of soccer athletes who'd never had an ACLR.


When the athletes were fresh, both groups scored on average 4 on the LESS. However immediately after an on-field training session, the ACLR group scored on average 7 compared to 4 in the group who had never previously had an ACLR.


The big question remains from van Melick and colleagues paper is; does this impaired movement quality lead to a 2nd ACL injury?
