The influence of gluteal muscle strength deficits on dynamic knee valgus: a scoping review

Anterior cruciate ligament (ACL) injuries are caused by both contact and non-contact injuries. However, it can be claimed that non-contact ones account approximately for 70% of all cases. Thus, several authors have emphasized the role of reduction of muscle strength as a modifable risk factor referred to non-contact ACL injury, with the latter being targeted by specifc training interventions. The present paper wants to review the available literature specifcally on the relationship between dynamic knee valgus, gluteal muscles (GM) strength, apart from the potential correlation regarding ACL injury. After a research based on MEDLINE via PubMed, Google scholar, and Web of Science, a total of 29 articles were collected and thus included. Additionally, this review highlights the crucial role of gluteal muscles in maintaining a correct knee position in the coronal plane during diferent exercises, namely walking, running, jumping and landing
