What is Arthritis?

Arthritis is a medical condition which affects the body’s joints and is a major cause of debilitating pain and disability for many people. In fact, up to 50 million American adults reported being told by a physician that they have some type of arthritis.

There are more than 100 types of arthritis. But, the most common form is osteoarthritis, which develops as we age. In this condition, the thin cartilage covering on the ends of the bones becomes worn and frayed, resulting in inflammation, swelling and pain. It affects nearly 27 million Americans, most of whom are 45 and older.

Arthritis can also occur following injury to a joint. This is known as traumatic arthritis. It may develop months or years after a severe sprain, torn ligament or broken bone.

Rheumatoid arthritis is a systemic disease in which the immune system turns against itself. Instead of protecting the joints, the body produces substances that attack and inflame the joints. 1.3 million adult Americans have been diagnosed with Rheumatoid arthritis.1 It most commonly occurs in the hands and feet.
