It has a fleshy insertion onto the linea aspera of the femoral shaft and a tendinous insertion onto the adductor tubercle on the medial condyle of the femur.

(In evolutionary terms, the medial collateral ligament of the knee joint may be a downward continuation of the latter).

Between these 2 insertions is a gap (hiatus) through which the femoral artery and vein pass backwards into the popliteal fossa to become the popliteal vessels.

adductor magnus has a dual innervation from the obturator and sciatic nerves.
