FIG. 475. THE DISTAL ARTICULAR SURFACES OF THE KNEE-JOINT: THE INTERARTICULAR SEMI- 

 LUNAR FIBROCARTILAGES, AND THE EXTENSION OF THE ANTERIOR EXTREMITIES OF THESE IN THE 

 TRANSVERSE LIGAMENT OF THE SEMILUNAR FIBROCARTILAGES. THE COMMUNICATION BETWEEN 

 THE SUPERIOR TIBIOFIBULAR ARTICULATION AND THE SYNOVIAL SHEATH OF THE TENDON OF 

 THE POPLITEUS MUSCLE. (THE PROXIMAL EXTREMITY OF THE LEFT TIBIA WITH THE SEMI- 

 LUNAR FIBROCARTILAGES AND THE HEAD OF THE FIBULA, SEEN FROM ABOVE.) 



The capsule was divided above (proximal to) the semilunar fibrocartilages, the crucial ligaments 

 were cut across, and the femur was removeJ.
