What Do You Know About Osteoarthritis?
Osteoarthritis is the most common type of arthritis. Learn more about this disease by taking the following quiz. It's based on information from the National Institute of Arthritis and Musculoskeletal and Skin Diseases.
1. Which part of a joint does osteoarthritis usually affect?
You didn't answer this question.
You answered
The correct answer is
Cartilage is the slippery tissue that covers the ends of bones in a joint. Healthy cartilage allows bones to slip over one another. It also absorbs the energy from the moving joint. In osteoarthritis, the cartilage wears away, leaving the bones beneath it to rub together. This rubbing causes pain, swelling, and loss of motion. Tiny bits of bone and cartilage can break off inside the joint area. This causes more pain and damage.
2. Which of these makes it more likely to get osteoarthritis?

The correct answer is
Researchers think that osteoarthritis is caused by a combination of advancing age, excess body weight, past joint injury, and family history. But each person is different. In some people, the disease gets worse quickly. And in others, the symptoms are more serious. In most cases, osteoarthritis develops slowly. At first, joints may ache after you exercise or do other physical activity. The joints most often affected by osteoarthritis are the hands, knees, hips, and spine.
3. When a person gets osteoarthritis of the hip, where else might the pain show up?

The correct answer is
Osteoarthritis of the hip can cause severe disability. The pain can also appear in the groin, knees, inner thigh, and buttocks. The condition can limit how much a person can move and bend. This makes daily activities difficult. A cane or walker can reduce the stress on the hip, and medicine and exercise can help ease pain. The healthcare provider may recommend hip replacement if the pain is severe and doesn't get better with other methods.
4. How can an X-ray help a healthcare provider diagnose osteoarthritis?

An X-ray may not show joint damage early on in the condition. To help diagnose osteoarthritis, the healthcare provider will also note symptoms and when they appeared. They will also look at the affected joints. The provider will also do a physical exam and take a health history that describes the symptoms, and when and how they started. These are important to make sure symptoms are not caused by another health condition.
