Knee Arthritis

Abstract

Arthritis is caused by wear of the cartilage that covers the bones around joints. Cartilage provides a nice smooth surface to allow mobility. When this cartilage wears out, the bone eventually becomes exposed. The condition can affect any joint in the body. The knee is one of the most common joints to be affected. The condition can range from very mild to very severe. When the cartilage shows some minor wear in the joint, the arthritis is considered mild. Eventually, the cartilage can completely wear out and the underlying bone can become exposed. When this occurs, the arthritis is considered severe.
