Osteoarthritis is a condition in which the cartilage that protects and cushions
the joints breaks down over time. Eventually, the bones—formerly separated by
the cartilage—rub against each other, resulting in damage to the tissue and
underlying bone and causing painful joint symptoms.
Osteoarthritis, sometimes called degenerative joint disease or
osteoarthrosis, is the most common form of arthritis. It most often affects the
joints of the spine, fingers, thumbs, hips, knees, or toes.
