arthritis of the knee is an inflammatory disorder of the knee joint that is often painful. arthritis has many causes. osteoarthritis (oa) is caused by degeneration of cartilage in the knee. in its extreme form the menisci (cartilage) will be completely eroded and the femur will rub on the tibia bone on bone. osteoarthritis causes a chronically painful knee that is often more painful with activity. treatment is aimed at pain control with over-the-counter pain relievers. anti-inflammatory medications either over-the-counter or by your doctor's prescription are also quite helpful. more severe oa can be treated with narcotic pain medicines or a knee joint replacement in which a synthetic joint replaces your knee joint.
