Q

Rotate leg inward towards midline

A

Internal rotation of hip

Because of the anatomical configuration of the hip, there are no true primary internal rotators of the hip. Muscles that play a role in internal rotation when the hip is first flexed to 90 degrees are the tensor fasciae latae, adductors longus and brevis, pectineus and the anterior fibers of gluteus medius and minimus.
