The Effect of Shoe Outsole Containing Nanoilica Particles on Knee Valgus Angle in Athlete Females with Anterior Cruciate Ligament Injury during Drop Jump and Single Leg Landing

摘要

It is a well-known fact that the verisimilitude of sustaining the anterior cruciate ligament (ACL) injury in a noncontact situation is greater for females than for males, dramatically (1). In sports science, many researchers have studied the mechanism and the risk factors of ACL injury, and excessive knee valgus angle (KVA) has received considerable attention as a reason of higher incidence of ACL injuries athlete females (2, 3). But, the majority of studies in KVA focused on its gender and sport differences (2, 4) and although shoe properties has been shown to affect kinematic and kinetic motion patterns during high impact activities (5), the effect of it on KVA as a risk factor of ACL injuries is still under debate.
