b
Fracture of the femur
QuestionChoice
This X-ray shows the knee joint, and the arrow is pointing to the patella, a triangular sesamoid bone embedded within the quadriceps tendon. The patella articulates with the femur at the patellofemoral joint, aiding in knee extension by increasing the leverage of the quadriceps muscle. It also helps protect the anterior surface of the knee joint from external trauma. The posterior surface of the patella is covered with cartilage to facilitate smooth movement across the femoral condyles.
