The patella, commonly known as the kneecap, is found in the front of the knee joint. It is a small, round bone that plays a crucial role in the mechanics of the knee, protecting the joint and facilitating the movement of the leg. The patella connects the quadriceps muscle in the thigh to the tibia in the lower leg, enhancing the efficiency of leg extension during walking, running, and jumping. The patella also contributes to the overall stability of the knee joint, preventing dislocation and ensuring proper alignment during movement. It is essential for daily activities that involve leg mobility.
