(See Fig. 288.) Within the articular cavity the two crucial ligaments arise from the inter-condyloid fossa of the femur and pass to the non-articular surface on the upperaspect of the head of the tibia. These ligaments are derived from the capsular.

(Original.) ligament of the joint, a portion of the posterior part of that ligament beingisolated at an early stage of development by the backward development of thecondyles of the femur. The anterior surfaces of these ligaments are coveredby synovial membrane. They are strong and well developed and materiallystrengthen the joint by the firm manner in which they attach the femur to thetibia. 688 AMERICAN PRACTICE OF SURGERY. The capsule of the joint is re-enforced by special ligaments. The close re-lationship of the popliteal artery to the posterior ligament is shown in Fig. 288;this must be borne in mind in operations upon the posterior aspect of the structures bounding the joint anteriorly con
