What Is Osteoarthritis?
Osteoarthritis, or “wear-and-tear” arthritis, is the most common type of arthritis. Also known as degenerative joint disease or age-related arthritis, osteoarthritis is more likely to develop as people age. Inflammation and injury to the joint cause a breaking down of cartilage tissues, resulting in pain, swelling, and deformity. The changes in osteoarthritis usually occur slowly over many years, though there are occasional exceptions.

- The joint where the ankle and shinbone meet
