ARTICULATIONS 



The anterior cruciate ligament springs from the intermediate 

 rough area on the proximal surface of the tibia, immediately 

 anterior to the medial tubercle which surmounts the eminentia 

 intercondyloidea. From this it proceeds proximally, backwards, 

 and laterally, to gain attachment to the posterior part of the 

 medial surface of the lateral condyle of the femur (Fig. 1 18).

The posterior cruciate ligament springs from the posterior 

 sloping part of the intermediate rough area on the proximal 

 surface of the tibia, posterior to the eminentia intercondyloidea, 

 and posterior also to the attachments of the posterior horns 

 of both menisci. It proceeds proximally, forwards, and some- 

 what medially, and, crossing the anterior cruciate ligament, is 

 attached, in the fore part of the intercondylar fossa, to the
