Excerpt
Injury prevention (eg, neuromuscular training) is currently the only effective intervention to avoid short- and long-term complications linked to ACL injuries. A clear understanding of the underlying mechanisms that result in increased risk of ACL injury is essential to maximize the efficacy of these efforts. In the last two decades, numerous studies have characterized the ACL’s response to different motions and loading conditions. Among the factors associated with increased risk of ACL injury, the role of knee abduction in ACL injury mechanism has been surrounded by controversies and considerable debate. Strong in vivo evidence supports knee abduction as a primary contributor to the multiplanar mechanism of noncontact ACL injuries [
