Arthritis

"Anthros" in Greek means "joint" and "itis" means inflammation. Arthritis should therefore mean "joint inflammation." As many as 36 million people in the United States have some form of arthritis or joint inflammation. It is a major cause of lost work time and serious disability for many people.

Frequently Asked Questions about Arthritis

There are two types of arthritis:

Osteoarthritis
This is the most common type of arthritis. It is seen in many people as they get older, although it may begin when they are younger as a result of injury or overuse. It is often more painful in weight-bearing joints such as the knee, hip, and spine than in the wrist, elbow and shoulder joints. Joints may be more affected if they are used extensively in work or sports, or if they have been damaged from fractures or other injuries. In osteoarthritis, the cartilage covering the bone ends gradually wears away. This is what we call wear and tear arthritis. The joint inflammation causes pain and swelling. Continued use of the joint produces pain. Some relief may be possible through rest and modified activity.

Rheumatoid Arthritis
Rheumatoid arthritis is a long-lasting disease that can affect many parts of the body, including the joints. In rheumatoid arthritis, the joint lining swells, invading surrounding tissues, and producing chemical substances that attack and destroy the joint surface. This commonly occurs in joints of the hands and feet. Larger joints such as hips, knees and elbows also may be involved. Swelling, pain, and stiffness are usually present even when the joint is not used. Rheumatoid arthritis can affect people of all ages. However, more than 70 percent of people with this disease are over 30 years of age.
