How to Prevent Osteoarthritis

There are about 100 different types of arthritis. In general, arthritis means problems with the joints. A joint is a place in the body where two bones meet. Arthritis may also affect other body tissue near the joints including muscles, tendons, and ligaments. And, in some forms of arthritis, the whole body is involved.

Osteoarthritis (OA) is sometimes called degenerative joint disease or wear-and-tear arthritis. It is the most common type of arthritis. In OA, the cartilage wears away. Cartilage covers the ends of bones and acts as a cushion. If enough cartilage wears away, bone rubs against bone. The joint changes in OA cause pain, stiffness, and difficulty with movement.

Can you prevent OA?

OA is called wear-and-tear arthritis because it is a result of using joints every day. The older a person gets, the greater the wear-and-tear. Although you cannot completely prevent OA, there are things that you can do to help lessen every day stress on your joints and make it less likely that OA will happen, or get worse.

Maintain your ideal body weight.

  • Extra weight puts stress on your joints, especially your hips, knees, ankles and feet.

  • And, extra fat actually causes changes in the cartilage cells.

  • If you are overweight, talk with your health care provider about safe ways to lose weight.

Control blood sugar.

  • Studies show that high blood sugar levels increase the risk of getting OA.

Be active every day.

  • Exercise is the best way to prevent joint problems. It helps to keep joints from getting stiff and muscles strong. It's also a very important part of the treatment of arthritis.

  • At least 30 minutes of exercise, on most days, is the recommendation for most people. Talk with your health care provider about safe exercise for you.

  • Try the Arthritis Foundation's Walk With Ease program. Go to the website at or call 1-800-283-7800.

Avoid injury to joints.

  • Injuries increase your risk of getting OA.

  • Start slowly and work up to your goal. Each time you exercise, take 5 to 10 minutes to warm up with gentle movements and stretches. This helps to prevent injuries to muscles, joints, ligaments, and tendons.

  • Think about changing your exercises and activities from day-to-day. You will use different parts of your body and help to avoid stressing the same joints every day.

  • Be careful with your daily activities. Some activities put stress on joints. For example, it is much safer to carry heavy bags of groceries close to your body in paper or cloth bags, rather than using fingers and hands on plastic bag handles.

  • Use exercise equipment and protective gear as instructed. Make sure your safety gear is comfortable and fits well.

Pay attention to pain.

  • If you have joint pain lasting an hour or two after activity or exercise, you may have done too much. Rest the joint. Try an ice pack to relieve pain.

  • Talk with your health care provider about using ice packs and pain medication before and after you exercise.

Taking good care of yourself by keeping a healthy weight and exercising every day helps to prevent joint problems and helps you stay healthy, as well.
