paÂ·telÂ·la. , pl. patellae (pÄ-tel'Ä, -Ä) [TA] The large sesamoid bone that covers the anterior surface of the knee. It is formed in the tendon of the quadriceps femoris muscle and is attached to the tibia by the patellar tendon. Synonym(s): kneecap.
Normal knee anatomy. The patella is the bone we know as the knee cap. A groove in the end of the femur allows the patella to glide up and down when the knee joint is bent back and forth. In so doing, the patella guides the action of the quadriceps muscle in the lower leg. The patella also protects the knee joint.
