Knee

Overview of the Knee

The knee joint consists of three bones—the tibia, femur, and patella—and is unlike many other joints in the body because it only allows bending in one direction. Cartilage covers the bones where they meet in the joint for protection, and two menisci supply extra cushion for the end of the femur. There are also two ligaments connecting the femur and tibia, the anterior cruciate ligament (ACL) and the posterior cruciate ligament (PCL). The knee provides shock absorption, balance, and mobility for the rest of the body. See the animation for a visual representation.
