How the meniscus works
The knee joint is very important in allowing people to go about performing almost any activity.
The joint is made up of three bones: the femur (thigh bone), the tibia (shin bone), and the patella (knee cap). The surfaces of these bones within the joint are covered with a layer of cartilage.
This important surface allows the bones to smoothly glide against each other without causing
damage to the bone. The meniscus sits between the cartilage surfaces of the bone to
distribute weight and to improve the stability of the joint.
