from before backwards: (i) The anterior horn of the 

 medial meniscus on the medial side of the extreme anterior 

 part of the area. (2) The anterior crucial ligament and the 

 anterior horn of the lateral meniscus : these are placed side 

 by side, but the attachment of the former, which lies to the 

 medial side, overlaps that of the lateral meniscus. (3) The 

 posterior horn of the lateral meniscus on the summit of the 

 intercondylar eminence between its two tubercles. (4) The 

 posterior horn of the medial meniscus immediately behind 

 the intercondylar eminence. (5) The posterior crucial 

 ligament at the hinder part of the area.

between the bones of the leg and the talus, and the weight of 

 the body is transferred through it to the foot. It is a joint 

 of great strength ; its stability being ensured not only by the 

 powerful ligaments which surround it, but also by the close 

 interlocking of the articulating surfaces. 



The bones which enter into the formation of the ankle- 

 joint are the distal ends of the tibia and fibula and the 

 proximal, medial, and lateral surfaces of the talus. The distal
