A majority of the combined movements overlap with biomechanics that have been suggested to be associated with increased risk of knee injury. Objective To identify the frequency of occurrence of the ...

a motion which magnifies the valgus stress on the knee, thereby increasing the risk of injury. Women might also tend to perform these movements with a straight, rather than a flexed, knee ...

The resulting knee valgus, or "knock knee," may increase injury risk to the knee particularly the medial collateral ligament, meniscus and possibly the anterior cruciate ligament (ACL).

athletes should be specifically coached to avoid side arm pitching as this can lead to premature injury damage and career ending mechanical failure of the UCL. Side arm pitching produces a valgus ...
