3D Model

The patella is a sesamoid bone*, the largest in the body, in the expansion of the quadriceps tendon, which continues from the apex of the bone as the ligamentum patellae. The posterior surface of the patella is covered with cartilage and articulates with the two femoral condyles by means of a larger lateral and smaller medial facet.

The primary function of the patella is during knee extension. The fact that the patella sits atop the anterior surface of the femoral condyles, increases the angle at which the quadriceps tendon pulls on the shaft of the tibia. The patella also functions to allow for smooth movement of the knee in flexion and extension, and also protects the anterior surface of the knee joint.

A sesamoid bone is a small bone commonly found embedded within a muscle or tendon near joint surfaces, existing as focal areas of ossification and functioning as a pulley to alleviate stress on that particular muscle or tendon.
