True or False

1. False. More than half of people affected by arthritis are under age 65. Rheumatoid arthritis can affect people of all ages, even children. However, the population is aging. The number of people with arthritis is expected to rise from the current 46 million as the baby boom generation ages. The Centers for Disease Control estimates this number to reach 67 million by the year 2030.

2. True, but joints may ache for several reasons. If the lining of the joint becomes inflamed, you may have rheumatoid arthritis. If the cushioning cartilage in the joint becomes damaged or worn away, you may have osteoarthritis or "wear and tear" arthritis.

3. False. There are interventions to prevent or reduce arthritis-related pain and disability. These interventions include early diagnosis, weight control, physical activity, physical and occupational therapy and joint replacement, when appropriate.

4. True. Post-traumatic arthritis can develop after an injury to the knee. This type of arthritis is similar to osteoarthritis and may develop years after a fracture or ligament injury in the knee.

5. True. Sudden onset of arthritis is possible, but, generally, the pain associated with arthritis develops gradually. The joint may become stiff and swollen, making it difficult to bend or straighten the knee. Pain and swelling are worse in the morning or after a period of inactivity. Pain also may increase after walking stair climbing or kneeling.

6. False. Researchers are making progress in finding the underlying causes for the major types of arthritis. In the meantime, orthopaedists, working with other physicians and scientists, have developed many effective treatments for arthritis.

7. True. However, arthritis can occur in other joints, too. For instance, arthritis at the base of the thumb is common. It occurs more in women than in men and usually after the age of 40.

8. False. Rheumatoid arthritis is not an inherited disease, although researchers believe that some people have genes that make them susceptible to the disease. People with these genes will not automatically develop rheumatoid arthritis.

9. True. However, research is underway to develop techniques to replace or "grow" cartilage in places where it has been worn away.

10. False. Regular exercise slows the loss of muscle mass, strengthens bones, and reduces joint and muscle pain. Inactivity can lead to weak muscles around the joint and result in joint instability.

Multiple Choice

1. D. More than 100 diseases that affect joint areas are called arthritis.

2. E. All listed. Nearly all vertebrates can suffer from osteoarthritis.

3. E. All listed. See your doctor for a complete medical evaluation.

4. B. Your doctor will prescribe a treatment program that meets your needs.

5. C. 46 million. The number is approximately one in five people.

6. E. $128 billion. The cost of arthritis equals a moderate recession.
