The Knee-joint, like the hip, is never fully extended, the capsule is strengthened by strong lateral ligaments ; the external lateral runs downward and backward from the external condyle to the front of the head of the fibula; its anterior fibres are continuous with the origin of the extensor longus digitorum. The popliteus also performs the function of an external lateral ligament, since it is attached above to the femur and fabella, and below 1o the external semilunar cartilage and the head of the fibula. During extreme flexion, which is the usual position of the joint, the Knee-joint of Petrogale laid open. Pat. Patella. F. Head of fibula. Q.E. Quadriceps. S.M. Synovial membrane. L.M.
