Axial MPR reconstructions of a right knee oriented in proximodistal sequence. (a) Intermediate vascular layer formed by a branch of the inferior lateral genicular artery and a terminal branch of the middle genicular artery. a: Inferior lateral genicular artery, b: arterial branch of the intermediate vascular layer, c: terminal branch of the middle genicular artery. (b) The inferior genicular arteries give rise to transversely running infrapatellar arteries, a: lateral transverse artery, b: medial transverse artery. (c) Transverse infrapatellar arteries anastomosing in proximity to the patellar apex. lc: lateral condyle of femur, mc: medial condyle of femur, pa: popliteal artery.
