The bones of the knee and the leg include the femur, which is the large thigh bone; the tibia and fibula, which are the leg bones between the knee and ankle; and the patella, which is sometimes called the kneecap.
Below the knee is the tibia (shin bone) and fibula. The kneecap is also called the patella. It rides on top of the lower portion of the femur and the top portion of the tibia. The muscles and ligaments connect these bones, and the space between them is cushioned by fluid-filled capsules (synovia) and cartilage.
