Exercise Helps Knee Osteoarthritis
Patients with high self reported physical activity and a timed 20 meter walk test had better performance than patients who were not active. Even a small increase in activity was related to better walking function. Other studies have shown that active patients who engage in vigorous forms of exercise did not increase the risk of developing osteoarthritis of the knee.
We don't know what causes OA. It is the number one chronic disease and the most common form of arthritis. OA is characterized by a progressive loss of cartilage that is often accompanied by the development of bone cysts. Swelling and stiffness occur and this causes pain when the joint is used. It is undoubtedly genetic and is also related to obesity. One wonders, however, if the weight gain came first or after, since people with pain in their lower extremities (hips and knees) stop being as active. Even small degrees of weight loss can help the symptoms, but it is hard to lose weight if one is sedentary so it is a vicious cycle.
If you have had pain, swelling and stiffness in your knees for 6 weeks or longer it may be Osteoarthritis. Don't ignore it. Get it diagnosed and get with a good exercise program to keep your joints as healthy as possible.
