Osteoarthritis, also called degenerative arthritis, is a
disease that causes the breakdown of the cartilage in
joints. Normally, cartilage acts as a smooth, cushioning
material inside joints. In osteoarthritis, the cartilage
becomes rough and flaky, and small pieces break off. The
bone surface of the joint also becomes rough and irregular.
As a result, movement of the joint becomes painful and
difficult.
