236 THE ARTICULATIONS OF THE HORSE 
The lateral meniscus does not cover the lateral and posterior part of the tibial con- 
dyle, over which the tendon of origin of the popliteus muscle plays. The peripheral 
border is thick and convex, the central one very thin and concave. The fibrous 
ends or ligaments are attached to the tibia in front of and behind the spine. The 
lateral meniscus has a third attachment by means of an oblique band (Ligamentum 
femorale menisci lateralis) which passes from the posterior end to the posterior 
part of the intercondyloid fossa of the femur.

The ligaments of the medial meniscus (Ligamenta tibialia anterius et posterius menisci medi- 
alis) are attached in front of and behind the medial eminence of the spine. The anterior ligament 
of the lateral meniscus (Ligamentum tibiale anterius menisci lateralis) is attached in front of the 
lateral eminence of the spine. The posterior one bifurcates; the lower branch (Ligamentum tibiale 
posterius menisci lateralis) is inserted at the popliteal notch, the upper (Ligamentum femorale 
menisci lateralis) in a small fossa in the extreme posterior part of the intercondyloid fossa. 
The joint capsule is attached to the margin of the tibial articular surface, 
but on the femur the line of attachment is for the greater part about half an inch 
(ca. 1 em.) from the articular margin. It is also attached to the convex borders of | 
the menisci and to the cruciate ligaments. It is thin in front, where it consists
