What Does the Patella Do?
Function. The primary functional role of the patella is knee extension. The patella increases the leverage that the quadriceps tendon can exert on the femur by increasing the angle at which it acts.

The tendons of the knee. The patellar tendon attaches the bottom of the kneecap (patella) to the top of the shinbone (tibia). It is actually a ligament that connects to two different bones, the patella and the tibia. The patella is attached to the quadriceps muscles by the quadriceps tendon.

Can you walk without a kneecap?

You can walk without a kneecap. Your kneecap, known as the patella, is a small bone that protects your knee joint. In those cases, though, surgeons do not create or install kneecap prostheses—because you can walk without a kneecap. Kneeling, however, may be a challenge without one, requiring protective gear.
