---- Fibula 



254. Right knee joint, articulatio germ. 



Sagittal section at about the middle of the joint. Lateral half, viewed 

 from the medial side; somewhat schematic. 



(The meniscus lateralis has been removed.) 



Articulatio genu (continued) (see also Figs. 253, 255257 and 259). It has inside 

 it the ligamenta cruciata genu anterius et posterius. Each of these goes from the surface 

 turned toward the fossa intercondyloidea of one condylus femoris downward to the region of the 

 eminentia intercondyloidea tibiae; in the extended position the anterior ligament is directed 

 obliquely forward, the posterior somewhat obliquely backward. Together they assume the form 

 of an X and are connected by loose connective tissue and fat not only with one another, but 

 also with the posterior wall of the capsula articularis. They are ensheathed by synovial membrane.
