機能

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.

臨床的意義

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.
