muscle, and ends on the head of the fibula. A small synovial bursa 

 intervenes between the ligament and the lateral condyle of the tibia. 



Dissection. — Make a transverse incision through the femoro-patellar 

 • apsule just proximal to the patella, and longitudinal incisions on each 

 side of the patella — through the capsule and the femoro-patellar liga- 

 ments — so that the bone, with its three ligaments intact, may be turned 

 downwards. 



Now dissect away the femoro-tibial capsule and the accumulations 

 of fat, so that a clear view of the cruciate ligaments and the menisci 

 may be obtained.

 The lines of attachment of the synovial linings of the joint-capsule are indicated in red. 



The anterior cruciate ligament (ligamentum cruciatum anterius) 

 passes obliquely from the depression on the intercondyloid eminence of 

 the tibia to the medial face of the lateral condyle pf the femur.. The 

 'posterior cruciate ligament (ligamentum cruciatum posterius) crosses the 

 medial surface of the anterior. It arises from the medial part of the 

 popliteal notch of the tibia and the adjacent part of 'the posterior inter- 

 condyloid fossa. An oblique course forwards and upwards carries 

 it to its point of fixation to the lateral face of the medial condyle of 

 the femur.
