Knee osteoarthritis is the most common form of osteoarthritis in the United States. It is caused by progressive degeneration of the cartilage in the knee joint, which protects bones in this area from rubbing against each other. While there is no cure for osteoarthritis, also referred to as wear-and-tear arthritis or degenerative joint disease, treatments can help reduce pain and inflammation.
