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.
The fourth bone of the knee is the patella. Commonly referred to as the kneecap, this nearly heart-shaped bone at the center of the knee helps extend the knee and protect the joint from impact. A tendon at the top of the patella and a ligament at the bottom hold the bone in place.
