The intra-articular structures of the knee-joint are more important and more numerous than in any other joint of the body.

These interarticular ligaments are distinguished from each other as the anterior or lateral and the posterior or medial. They cross each other like the limbs of an X, yet they remain distinct throughout, and each has its own partial synovial covering. They lie within the articular capsule, and extend between non-articular surfaces in relation to
