A normal knee

Normal KneeSitting, standing and walking depend on the bending and straightening of the leg at the knee. This hinge-like movement of the joint depends on smooth cartilage and strong muscles to move.

Joint disease or trauma may result in stiffness, swelling and pain in your knee. This causes difficulty with you doing the simplest things, such as walking or getting out of a chair. A joint replacement may help you resume your activities with greater ease.
