front of the internal. It prevents the front part of the external 

 semilunar fibro-cartilage from moving too far backwards during 

 flexion of the joint. 



The synovial membrane invests the inner surface of the capsular 

 ligament. On reaching the semilunar fibro-cartilages it is reflected 

 over their upper and under surfaces, and is then conducted by the 

 coronary ligaments to the margins of the tuberosities of the tibia. 

 Between the front of the head of the tibia and the patella the 

 membrane covers a collection of fat, known as the infrapatellar

pad, and in this situation it is raised into certain folds, called 

 ligaments, namely, the ligamentum mucosum and ligamenta alaria, 

 to be presently described. Above the patella the membrane 

 extends upwards in the form of a large pouch upon the front of the 

 shaft of the femur for about 2 inches above the upper border of 

 the patellar surface of the bone. This pouch lies beneath 

 the suprapatellar tendon of the quadriceps extensor cruris, and 

 communicates with the suprapatellar bursa, which is situated 

 immediately above it, and which extends upwards for about i inch ; 

 beneath the suprapatellar tendon.
