mentuin teres is a very strong iibrous band, which, in the usual 

 position of the joint, passes upward and outward to the head of the 

 femur and takes the greater part of the strain of the joint ; above 

 it is a synovial fold containing fat. 



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 longiis digitorum. The popliteus 

 also performs the function of an external lateral ligament, since it 

 is attached above to the femur and fabella, and below to 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 Fctrugale laid open.
