We know there are a lot of misconceptions out there about osteoarthritis (OA). To help separate fact from fiction, we developed this list of the 12 most common myths about OA.

1. Myth: I can’t exercise with joint pain. Fact: Low impact exercises such as walking, swimming, Tai Chi, and Yoga can actually lessen joint pain, strengthen muscles that support joints, and improve symptoms of OA. Many programs are available in the community to promote physical activity.
2. Myth: Arthritis is inevitable as I age. Fact: The risk of developing OA does increase with age, but there are many things you can do to lower your risk. These include weight management, resting and recovering after joint-related injuries, and consulting with your doctor to understand your risk and come up with a prevention strategy.
3. Myth: Diet doesn’t affect your joints. Fact: Being overweight puts extra strain on your joints (1 pound of weight = 4 pounds of pressure on your knees), increasing the likelihood that you will develop OA and increasing the rate at which OA will progress. Eating a healthy diet helps you maintain a healthy weight.
4. Myth: OA is joint wear and tear. Fact: Joint tissues, like cartilage, are not designed to wear out simply due to aging. We now know that OA is a complex disease that also causes changes in muscle, bone, and other joint tissues.
5. Myth: Cracking knuckles causes OA. Fact: While cracking your knuckles can hurt tendons in your hands, it will not cause OA.
6. Myth: Running is bad for your knees and causes OA. Fact: Research has shown that recreational running, including marathons, does not cause knee OA.
7. Myth: Active teenagers cannot get OA. Fact: Sports injuries can increase a teenager’s chances of developing OA in early adulthood. Including specific training components that will improve strength in lower limbs and joints, balance, and athletic performance will reduce the risk of injury during practice and competition and, therefore, reduce the risk of developing OA later in life.
8. Myth: My job doesn’t involve repetitive motion, so I won’t get OA. Fact: Those who have jobs that involve repetitive motions are at greater risk of developing OA; however, people with desk jobs are also at an increased risk. Taking breaks occasionally to stretch and walk around can strengthen muscles and decrease this risk.
9. Myth: I don’t need to see a doctor for joint pain. Fact: It is incorrect to assume that nothing can be done to manage OA symptoms or that surgery is the only option. Exercise, weight loss, pain management techniques, alternative therapies, and medications (both prescription and over-the-counter) are all ways that joint pain can be managed. Consulting a doctor is the best way to find out how to best manage joint pain.
10. Myth: My parent had OA, so I will get it too. Fact: While your chances of developing OA are greater if one of your parents had it, it is not definite. Regularly exercising and maintaining a healthy weight may decrease your risk of developing OA, or slow progression if you already have OA.
11. Myth: Weather can cause arthritis. Fact: Weather can’t cause an otherwise healthy individual to develop arthritis, but damp climates may worsen the pain of someone who already has arthritis.
12. Myth: Arthritis is not a serious health problem. Fact: Arthritis is the most common cause of disability in the United States, affecting over 53.2 million people — about one in every four U.S. adults — and their families. OA, specifically, affects over 32.5 million U.S. adults. The economic burden is also large, with estimated costs of more than $136.8 billion a year — $164 billion in lost wages, and $65 billion in direct medical care. Fortunately, you can make sure you’re not an arthritis statistic. You can start today by eating right, exercising, and taking care of your body.
