ABSTRACT
Clinical Applications The saphenous nerve is a cutaneous branch of the femoral nerve, arising in the femoral triangle. It descends laterally to the femoral artery and enters the adductor canal. The nerve exits from the lower part of the canal, emerging between the sartorius and gracilis muscles. The nerve becomes subcutaneous below the sartorius at the medial side of the knee. It descends down the medial border of the tibia immediately behind the long saphenous vein. The nerve crosses with the vein in front of the medial malleolus and extends as far as the base of the great toe. The saphenous nerve supplies an extensive cutaneous area over the medial side of the knee, leg, ankle, and foot.
