The most common type of knee arthritis is osteoarthritis. Also called wear-and-tear arthritis or degenerative joint disease, osteoarthritis is essentially acquired from daily wear and tear of the joint. As the disease progresses the cartilage of the joint is gradually worn away exposing the bare bone. Other types of arthritis include rheumatoid arthritis, gouty arthritis, and lupus arthritis.
