The patella is the lens-shaped (sometimes escribed as "triangular") bone that forms the kneecap.
It is located in the tendon of the quadriceps femoris muscle of the thigh where it lies in front of the "knee-joint" between the femur and the tibia (as shownd below).
For a diagram
showing its location relative to the fibula, tibia, femur, and other bones of the leg, ankle, and foot, see the simple sketch diagram below.
The functions of the patella include:
- increasing the leverage of the tendon of the quadriceps muscle
- maintaining the position of the tendon when the knee is flexed
- mechanically protecting the knee joint
