What is osteoarthritis?
Osteoarthritis is a type of arthritis that is caused by the breakdown and eventual loss of the cartilage in one or more joints. Cartilage is a protein substance that serves as a “cushion” between the bones of the joints. Osteoarthritis commonly affects the hands, feet, spine, and large weight-bearing joints, such as the hips and knees. Most cases of osteoarthritis have no known cause.
