Osteoarthritis (OA) is the most common form of arthritis.
Some people call it degenerative joint disease or “wear and tear” arthritis. It occurs most frequently in the hands, hips, and knees.
With OA, the cartilage within a joint begins to break down and the underlying bone begins to change. These changes usually develop slowly and get worse over time. OA can cause pain, stiffness, and swelling. In some cases it also causes reduced function and disability; some people are no longer able to do daily tasks or work.
You may have already tried other treatments for your arthritis, like over-the-counter pain medicines and corticosteroid injections. If you still have significant symptoms, treatment might be a good choice to help reduce your pain, stiffness, and swelling.
