Rotatory motion decreases with further extension and, at 5 degrees of flexion, the knee has 23 degrees external and 10 degrees internal rotation. It is important to understand how the body moves and how muscles work together to generate movement. Its primary role is to restrain inversion in a neutral or dorsiflexed position, restrains subtalar inversion, thereby limiting talar tilt within the ankle mortise.
