A sesamoid bone found in the knee, commonly known as the knee cap.
The patella or knee cap is the bone between the fibula and femur. Each leg has a patella to protect its knee joint. The patella serves two
To protect the knee from physical trauma.
To enhance the leverage
that the quadriceps tendon can exert on the femur, thereby increasing muscle efficiency.
The apex of the patella
faces inferiorly and connects to the tibia tuberosity through the patella
ligament that attaches to the anterior surface. The base of the patella faces
superiorly and is the attachment point for the quadriceps tendon.
surface of the patella contains the medial and lateral facets that articulate
with the condyles of the femur. The lower posterior region of the patella has vascular canaliculi, small channels within the bone, which form the infrapatellar fat pad.
