The knee is the largest joint in the body and is vital to movement and ambulation. The knee joint is made up of the femur bone, the tibia bone, the fibula, and the patella. There are four major ligaments that give the knee stability — the medial collateral ligament, the lateral collateral ligament, and the two cruciate ligaments, the anterior cruciate and posterior cruciate ligament in the middle of the knee. There are two types of cartilage in the knee — a thick fibrocartilage, the meniscus, which acts as a shock absorber and helps distribute load evenly in the knee joint. There is an inside, or medial, meniscus, and an outside, or lateral, meniscus. The other cartilage is the articular or hylan cartilage, which is a smooth-bearing surface on the end of the femur and on top of the tibia and underneath the kneecap. Breakdown of this articular cartilage is what is referred to as arthritis. Approximately 6 million people visit orthopaedic surgeons each year because of knee problems.
