The knee is a sophisticated design with three long leg bones (tibia, fibula, and femur), which join at the knee cap. Now add several connecting ligaments and muscles to make it move and to ensure joint stability.

The knee has many moving parts, but they all work together to function like a hinge that lets the leg bend and straighten repeatedly. The design allows for a variety of positions and movements, such as walking, sitting, squatting, and kneeling.
