The mechanism by which each type develops is determined by these different underlying causes.
HYPEREXTENSION CHARACTERIZED BY SKELETAL CHANGES The chief underlying causative factor in the first group is the lack of sufficient power in the quadriceps group to lock the knee in extension against resistance.
