Actions of the tensor fasciae latae (TFL) include

The tensor fasciae latae acts on the hip to flex the thigh, abduct it away from the midline, and medially rotate the thigh when the hip is flexed. Its position on the lateral hip and its pull on the iliotibial band help with these actions and also aid in pelvis and knee stability during movement. It does not extend the hip, nor adducts the thigh, and it does not move the ankle. So hip flexion, abduction, and medial rotation best describe its primary actions.
