Difference Between Rheumatoid Arthritis & Osteoarthritis

Arthritis is a general term for over 100 different diseases. Rheumatoid arthritis is a disease that is chronic and includes inflammation of the joints. Osteoarthritis is a degenerative disease that destroys the joints. It is the most common arthritis. Treatment and symptoms are similar, but there are some differences.

Causes

Rheumatoid arthritis is caused by the inflammation of the synovial membrane, which protects the joints. The wearing of the cartilage, which protects the joints, causes osteoarthritis.

Effects

Rheumatoid arthritis begins with small joints first and may involve several joints at the same time. Osteoarthritis affects one joint at a time.

Symptoms

Rheumatoid arthritis includes joint pain, joint swelling and tender areas. Osteoarthritis includes joint pain, but it occurs after using the joint. There is tenderness and some swelling, and bone spurs may form around the joint.

Treatment

Drug treatments for rheumatoid arthritis include NSAIDs, steroids, anti-rheumatic drugs and sometimes surgery. Drug treatments for osteoarthritis include NSAIDs, topical creams, cortisone shots and possible surgery.

Identification

Rheumatoid arthritis affects more women than men, occurs usually between the ages of 40 and 60, and is more apt to occur in people who smoke. Osteoarthritis occurs in more women than men, usually in people over 40, people who suffer from joint injuries and people who are obese.
