Osteoarthritis, the most common form of arthritis, occurs when the joint cartilage that cushions the end of bones wears down. The surface of the bones becomes rough, which causes bone to rub on bone and can be very painful.
Patients may experience pain, swelling and reduced motion in their joints. Symptoms develop slowly and typically get worse over time. The most commonly affected areas are the hands, hips, knees, neck and spine.
