LIGAMENTS OF THE KNEE JOINT. 



spinous process of the ilium, incorporates itself with the 

 anterior capsular ligament, and goes to be attached to the 

 F, G . 244. front of the femur, near 



the trochanter minor. 



The cotyloid ligament 

 (Fig. 244) consists of fibro- 

 cartilage, placed round 

 the margin of the aceta- 

 bulum to deepen its cavi- 

 ty. Its fibres are circular 

 and strong, and thicker 

 above than behind. Its 

 free edge is sharp, and 

 within the capsular liga- 

 ment it is connected with 

 some ligamentous fibres 

 which stretch across the 

 notch of the acetabulum, called the transverse ligament 



Ligamentum teres, round, or interarticular ligament, (Fig. 

 244.) This is a round or triangular cord, about an inch 

 and a half long, within the capsular. It is seen, by open- 

 ing the latter, to be attached at one extremity to the 

 depression in the head of the femur, and by the other 

 which bifurcates, to the depression and borders of the 

 notch of the acetabulum. 



The synovial membrane forms a complete sac, which lines 

 the acetabulum, covers the cotyloid and round ligament, 

 and the head and neck of the femur ; it also adheres to 

 the reddish fatty mass filling the rough surface of the 

 acetabulum. 



LIGAMENTS OF THE KNEE-JOINT. 



The bones comprising this joint are the condyles of the 

 femur, the patella, and head of the tibia. This is a very 

 complicated joint, including a variety of ligaments.
