Essentially, the kneecap (patella) is a small triangular bone that rests on the front of your knee and is one of the many parts that make up the knee joint. The knee joint also includes muscles, ligaments, and leg bones. The kneecap's primary function is to protect the knee joint and improve the leverage of the quadriceps muscle, which helps straighten the leg. The knee joint, as a whole, allows for a wide range of movements, including bending, straightening, and slight rotation.
