Alternative medicine

Complementary and alternative medicine treatments that have shown promise for osteoarthritis include:

• Acupuncture. Some studies indicate that acupuncture can relieve pain and improve function in people who have knee osteoarthritis. During acupuncture, hair-thin needles are inserted into your skin at precise spots on your body.
• Glucosamine and chondroitin. Studies have been mixed on these nutritional supplements. A few have found benefits for people with osteoarthritis, while most indicate that these supplements work no better than a placebo. Glucosamine and chondroitin can interact with blood thinners such as warfarin (Jantoven, and cause bleeding problems.
• Avocado-soybean unsaponifiables. This nutritional supplement — a mixture of avocado and soybean oils — is widely used in Europe to treat knee and hip osteoarthritis. It acts as an anti-inflammatory, and some studies have shown that it can slow or even prevent joint damage.
• Omega-3 fatty acids. Omega-3s, found in fatty fish and fish oil supplements, might help relieve pain and improve function.

Talk to your doctor about supplements you're considering.
