Osteoarthritis

Osteoarthritis (OA) is a type of joint disease that results from breakdown of joint cartilage and underlying bone. The most common symptoms are joint pain and stiffness initially, symptoms may occur only following exercise, but over time they may become constant. Other symptoms may include joint swelling, decreased range of motion, and, when the back is affected, weakness or numbness of the arms and legs. The most commonly involved joints are those near the ends of the fingers, at the base of the thumb, neck, lower back, knee, and hips. Joints on one side of the body are often more affected than those on the other. Usually the symptoms develop over some years. They can affect work and normal daily activities. Unlike other types of arthritis, only the joints are typically affected.

Osteoarthritis is the most common form of arthritis, affecting about 237 million people (3.3% of the world population).  Among those over 60 years old, about 10% of males and 18% of females are affected. It is the cause of about 2% of years lived with disability. In Australia, about 1.9 million people are affected, and in the United States, 30 to 53 million people are affected. It becomes more common in both sexes as people become older.
