Knee Osteoarthritis Is
Most Common Disability in U.S.

by Dr. Brett L. Lukert, DC

When discussing health conditions resulting from the cumulative effects of repetitive stress, traumatic injuries and obesity, there is probably no better example than osteoarthritis. Osteoarthritis is a gradual, progressive and chronic form of arthritis known as "wear and tear" arthritis. It will produce pain but is not considered to be inflammatory (at least severely) such as with rheumatoid arthritis.

Osteoarthritis is a degenerative condition that occurs when the tissue that protects the bones (called cartilage) wears away. Cartilage is a type of fibrous connective tissue that protects our bones by cushioning and lubricating the joints. When the cartilage deteriorates, we lose the joint space between the bones and the "shock absorption" qualities that cartilage provides. Since cartilage has a limited ability to regenerate and because degenerative changes are irreversible, it is in our best interest to take care of our joints before osteoarthritis can set in.

Osteoarthritis of the knee is the most common type of osteoarthritis, affecting 27 million Americans. It is the most common cause of disability in the United States, and it is estimated that one in two Americans are at risk throughout their lifetime. Symptoms include knee pain and stiffness (especially in the morning), pain going up and down stairs, and limited range of motion. Stiffness can be worse after prolonged sitting, and pain can be worse after overuse activities.

Treatment options for knee osteoarthritis vary depending on the degree of severity. Severe cases generally focus on strategies that inhibit cartilage damage and promote cartilage repair. Glucosamine and chondroitin sulfate supplementation is one such option that has been shown to help. A recent study conducted by the National Institute of Health found that 79 percent of moderate-to-severe knee pain sufferers experienced significant pain relief with glucosamine and chondroitin sulfate supplements. Other supplements that have been shown to reduce symptoms include omega-3 fatty acids, MSM (methylsulfonylmethane) and calcium.

Other treatment options for knee osteoarthritis include exercise, weight loss, knee taping, steroid injections, physical therapy, topical creams, and medication. If detected early, most people can adequately manage their symptoms.

Since osteoarthritis cannot be cured, only managed, the best treatment of all is prevention. The Arthritis Foundation "stresses the importance of weight control to limit the impact of knee osteoarthritis. Obesity is a known risk factor for osteoarthritis in weight-bearing joints. For patients who are overweight, losing weight and becoming physically active will improve their pain and slow down progression of the disease."

Osteoarthritis is another example of a condition that demonstrates how maintaining a healthy weight and an active lifestyle can help us be healthy, live healthy and stay healthy!
