FIG. 471. ARTICULATIO GENU, THE KNEE-JOINT: LIGAMENTA CRUCIATA, CRUCIAL LIGAMENTS, AND LIGAMENTUM 

 MENISCI LATERALIS, POSTERIOR OR ASCENDING BAND OF THE EXTERNAL SEMILUNAR FIBROCARTILAGE (ELLIS) 

 OR LIGAMENT OF WRISBERG (MACALISTER), (VARIETY'). COMMUNICATION OF THE SYNOVIAL SHEATH OF THE 

 TENDON OF THE POPLITEUS MUSCLE WITH THE SYNOVIAL CAVITIES OF THE KNEE-JOINT AND OF THE SUPERIOR 

 TIBIOFIBULAR ARTICULATION. (THE RIGHT KNEE-JOINT, SEEN FROM BEHIND.) 



The posterior portion of the Capsular ligament, between the external and internal lateral ligaments, has been removed, 

 except for a strip left above close to the femoral attachment, which has been turned upwards; the synovial sheath 

 of the tendon of the popliteus muscle has been opened at its inner side, and its posterior wall has been turned out- 

 wards with the tendon and the proximal portion of the popliteus muscle. 



Chough this band is called a variety by Toldt, it is, in fac, usually present, but its situation varies ; inasmuch as it passes, some- 

 times behind (as her"), and sometimes before, and sometimes as a double band behind and before, the posterior or internal crucial ligament. 

 Its strength and thickness varies much, but it is seldom entirely wanting. TR. 



Articulatio genu The knee-joint.
