THE INFERIOR EXTREMITY 



Portions of the tendons of the biceps femoris, semimembranosus, 

 sartorius, semitendinosus, gracilis, and popliteus, together with 

 small pieces of the heads of the gastrocnemius, should be left 

 in place in order that their connections with the ligaments of 

 the joint may be studied. The quadriceps extensor may be 

 divided about three inches proximal to the patella, and the distal 

 part allowed to remain in position.

Capsula Articularis. The capsule of the knee joint, 

 together with the tibial collateral ligament and the oblique 

 popliteal ligament, form a complete investment for the joint. 

 In some places the fibrous or peripheral part of the capsule 

 has disappeared and has been replaced either by bone and 

 cartilage or by tendon, and in other places it has been 

 strengthened and extended by the incorporation of adjacent 

 portions of fascia and tendons; thus, anteriorly, the patella
