What is osteoarthritis?
Osteoarthritis, sometimes called OA, is a type of arthritis that only affects the joints, usually in the hands, knees, hips, neck, and lower back. It's the most common type of arthritis.
In a healthy joint, the ends of the bones are covered with a smooth, slippery tissue called cartilage. The cartilage pads the bones and helps them glide easily when you move the joint. With osteoarthritis, the cartilage breaks down and becomes rough. Sometimes, all the cartilage wears away and the bones rub together. Bumps of extra bone called bone spurs may grow in the joint area.
