True regarding the hip joint is :

A i.e. Medial rotation & abduction is caused by gluteus medius & minimus Gluteus medius & minimus are powerful abductors of hip & also cause medial rotation (not lateral rotation). Gluteus maximus is extensor & lateral rotator of hip. Saorius is flexor, abductor & lateral rotator of hip & flexes knee joint. (i.e. palthi posture/ sitting crossed leg / position in which tailors sit). Tensor fascia lata is flexor, abductor & medial rotator of hip; helps in knee extension. Hyper extension is prevented by iliofemoral ligament (Ligament of Bigelow) not by capsular thickening Femoral nerve (L2L3L4) supplies flexor muscles of hip (anterior compament of thigh) i.e. - Saorius, Quadriceps femoris (rectus femoris + vastus laterlis, medialis & intermedius), aicularis genu not lateral rotators of thigh (eg. Gluteus maximus)
