FIG. 472. ARTICULATIO GENU, THE KNEE-JOINT: PARS SYNOVIALIS CAPSUL/E ARTICULARIS, SYNOVIAL MEMBRANE 

 OF THE KNEE-JOINT; PLICA SYNOVIALIS PATELLARIS, Mucous LIGAMENT; PLIC/E ALARES, ALAR LIGAMENTS; 

 BURSA SUPRAPATELLARIS, BURSA BENEATH THE SUPRAPATELLAR TENDON. (THE RIGHT KNEE-JOINT, SEEN 

 FROM BEFORE AND WITHOUT.) 



The joint was first injected, and the injected material allowed to solidify ; the capsule of the joint was then prepared from 

 without, the quadriceps extensor cruris muscle being left intact ; subsequently the joint was opened by a section 

 passing through the quadriceps muscle and the upper part of the front of the capsule from one lateral ligament to 

 the other close to the attachment of the capsule to the femur, and the anterior wall of the joint together with the 

 distal portion of the quadriceps extensor muscle was turned down. The quadriceps was divided at a somewhat 

 higher level than the capsule, and the bursa beneath the suprapatellar tendon divided is the frontal plane, to show 

 the communication of this bursa with the joint. 



Articulatio genu The knee-joint.
