Tendinitis is an inflammation of the tendon, a flexible band of tissue that connects the muscles to the bones. The pull of the muscles is transmitted to the bone by the tendons, which allows movement. When the tendons are inflamed, the pulling action of the muscle is impaired and movement becomes painful. There are several large tendons around the knee area. When one or more of them becomes inflamed, this is called knee tendinitis.
