The main role of the patella is to constitute the knee joint, so that the quadriceps muscle is able to drive the lower leg with minimal force. The patella is the largest seed bone in the body and is located in front of the distal femur, within the quadriceps tendon, wide at the top and pointed at the bottom, rough at the front, with the articular surface at the back, and forms the patellofemoral joint with the femoral talus, which can be touched directly on the body surface. The quadriceps muscle contracts and transmits force to the patella, which in turn transmits force to the calf, thus driving the calf to move. Without the patella, the quadriceps would require more force to drive the lower leg to move, and the patient would be prone to fatigue and would not be able to walk normally with weight or participate in sports. Therefore, the patella is very important to the human body and should be protected. When the patella is directly impacted, a comminuted patella fracture can occur and poor fracture repair can affect the function of the entire knee joint.
