The lateral superior genicular artery is a branch of the popliteal artery that supplies a portion of the knee joint. Course It passes above the lateral condyle of the femur, beneath the tendon of the Biceps femoris. Branching It divides into a superficial and a deep branch; the superficial branch supplies the vastus lateralis, and anastomoses with the descending branch of the lateral femoral circumflex and the lateral inferior genicular arteries; the deep branch supplies the lower part of the femur and knee-joint, and forms an anastomotic arch across the front of the bone with the highest genicular and the medial inferior genicular arteries.
