Out of the knee, the ankle, the shoulder and the hip, which is the largest joint in the human body?

Not only is the knee the largest joint in the human body, but it's also the most complex, joining together the thigh bone, the shin bone, the fibula, and the kneecap. Containing a fluid-filled capsule, the knee is designed to move like a complicated hinge.
