Anterior cruciate ligament loading and mechanisms of loading during drop-land-cut and running

Using a novel rheological model of anterior cruciate ligament (ACL) loading, we estimated ACL force (FACL) in females during drop-land-cut and running manoeuvres, as well as the loading mechanism. In both tasks, peak loading occurred shortly following initial foot contact, but was larger during drop-land-cut tasks. Sagittal plane loading mechanism was the primary cause of FACL during foot-ground contact phase in both tasks.
