Inferior medial genicular artery

The medial inferior genicular artery arise from the popliteal artery beneath the medial head of Gastrocnemius. It then first descends along the upper margin of the Popliteus, to which it gives branches; it then passes below the medial condyle of the tibia, beneath the tibial collateral ligament, at the anterior border of which it ascends to the front and medial side of the joint, to supply the upper end of the tibia and the articulation of the knee, anastomosing with the lateral inferior and medial superior genicular arteries.
