patellar ligament are associated with the capsule, forming the anterior 

 wall of the joint. 



Between the apposed surfaces of the condyles, in the interior of the 

 joint, there are two short, cruciate ligaments and two thin plates of 

 fibrocartilage, the medial and lateral menisci. The anterior cruciate 

 ligament (lig. cruciatum anterius) passes from the lateral wall of the 

 intercondyloid fossa of the femur to the anterior end of the intercon- 

 dyloid eminence of the tibia. The posterior cruciate ligament passes 

 from the medial wall of the intercondyloid fossa of the femur to the 

 posterior intercondyloid fossa of the tibia. The medial meniscus 

 (meniscus medialis) lies on the articular surface of the medial condyle of 

 the tibia, and is connected by ligament with the anterior and posterior 

 intercondyloid fossae of the bone. The larger, lateral meniscus lies on 

 the lateral condyle of the tibia, and is attached by ligament anteriorly 

 to the medial portion of the articular surface, and posteriorly to the 

 medial wall of the intercondyloid fossa of the femur. 



C. The ankle-joint (articulatio talocruralis) is a ginglymus with a 

 considerable amount of spiral torsion. The articulating surfaces are 

 chiefly formed by the tibia and talus, but also by the fibular side of the 

 tibiofibula and the calcaneus. On the tibial side the calcaneotibial liga- 

 ment (lig. calcaneotibiale) connects the medial malleolus with the sus- 

 tentaculum tali. On the fibular side the calcaneofibular ligament (lig. 

 calcaneofibulare) connects the posterior portion of the groove for the 

 peronaei muscles forwards with the lateral surface of the calcaneus, and 

 a second ligament extends from the anterior margin of the groove back- 

 ward to the lateral surface of the calcaneus. The tibionavicular liga- 

 ment (lig. tibionaviculare) connects the anterior surface of the distal 

 end of the tibia with the dorsal surface of the navicular bone.
