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.
Next to the tibia is the fibula, the thinner, weaker bone of the lower leg. It is also known as the calf bone, as it sits slightly behind the tibia on the outside of the leg. The fibula is connected via ligaments to the two ends of the tibia. The patella, commonly known as the kneecap, is at the center of the knee.
