It prevents the femur from moving backwards onto the tibia, and the posterior cruciate ligament (PCL) prevents the femur from sliding forwards. There are two collateral ligaments, medial and lateral, that also help to provide support.

There is also articular cartilage that sits behind the patella. The knee is surrounded by bursae, fluid-filled sacs that help to cushion the knee joint.
A band or sheet of strong fibrous connective tissue connecting the articular ends of bones, binding them together to limit motion.
a laceration of the meniscus most commonly caused by abrupt twisting or hyperflexion of the knee joint.
