Osteoarthritis (OA) is the most common joint disorder. It is due to aging and wear and tear on a joint.


Osteoarthritis is a chronic disease of the joint cartilage and bone, often thought to result from "wear and tear" on a joint, although there are other causes such as congenital defects, trauma and metabolic disorders. Joints appear larger, are stiff and painful and usually feel worse the more they are used throughout the day.


Osteoarthritis is associated with the aging process and can affect any joint. The cartilage of the affected joint is gradually worn down, eventually causing bone to rub against bone. Bony spurs develop on the unprotected bones causing pain and inflammation.
