Knee anatomy, computer artwork. The knee joint is formed by the articulation of the femur (thigh bone, opaque, top) with tibia (shin bone, bottom centre). The smaller fibula (bottom left) is also seen. Articular cartilage (white), which protects the bone surface from wear and tear, is seen on the head of the tibia. Partially covering it are the menisci (cream crescent-shaped), which act as shock absorbers. At centre is the posterior cruciate ligament, a fibrous band of connective tissue that connects the femur and tibia and limits backwards movement of the joint.
