기능

The largest sesamoid bone in the body, embedded within the quadriceps tendon. Increases the mechanical advantage of the quadriceps muscle by increasing the lever arm for knee extension.

임상적 의의

Patellar fractures result from direct trauma or forceful quadriceps contraction. Patellar dislocation typically occurs laterally. Chondromalacia patellae (runner's knee) causes anterior knee pain from cartilage degeneration.
