 It passes between the sartorius muscle and the gracilis muscle, and, piercing the fascia lata, is distributed to the integument of the upper and medial part of the leg, anastamosing with the medial inferior genicular artery.The articular branches descend within the vastus medialis muscle, and in front of the tendon of the adductor magnus muscle, to the medial side of the knee, where they join with the medial superior genicular and anterior recurrent tibial artery.A branch from this vessel crosses above the patellar surface of the femur, forming an anastomotic arch with the lateral superior genicular artery, and supplying branches to the knee-joint.
