from in front. 



(The knee is flexed at a right angle ; the patella and the capsule of the joint have been removed, 

 the ligamentum cruciatum anterius has been cut off short at its points of attachment.) 



Articulatio geim (continued) (see also Figs. 253, 255 and 257). The ligamentum 

 cruciatum posterius (0. T. posterior or internal crucial ligament) lies behind the ligamentum 

 cruciatum anterius, crosses the same and is somewhat stronger. It has a broad origin from 

 the lateral surface of the condylus medialis femoris close to its anterior and inferior margin, 

 narrows to a flatly rounded cord and passes somewhat obliquely downward, backward, and 

 lateralward to the fossa intercondyloidea posterior tibiae and to the posterior surface of the 

 tibia; one band of fibres, arising in the medial portion, runs behind the ligament obliquely 

 lateralward to the posterior part of the meniscus lateralis (see 1'ig. 257).
