Arthritis

Definition

Arthritis is inflammation of one or more joints. A joint is the area where two bones meet. There are over 100 different types of arthritis.

Alternative Names

Joint inflammation

Causes

Arthritis involves the breakdown of cartilage. Cartilage normally protects a joint, allowing it to move smoothly. Cartilage also absorbs shock when pressure is placed on the joint, such as when you walk. Without the normal amount of cartilage, the bones rub together, causing pain, swelling (inflammation), and stiffness.

Joint inflammation may result from:

Usually the joint inflammation goes away after the cause goes away or is treated. Sometimes it does not. When this happens, you have chronic arthritis. Arthritis may occur in men or women. Osteoarthritis is the most common type.

Blood tests and joint x-rays are often done to check for infection and other causes of arthritis.

Your doctor may also remove a sample of joint fluid with a needle and send it to a lab to be checked.

Treatment

The goal of treatment is to reduce pain, improve function, and prevent further joint damage. The underlying cause often cannot be cured.
