Weight Loss Is the Best Medicine For Knee Osteoarthritis Sufferers

Long-term intensive diet combined with moderate exercise can improve mobility and reduce pain by as much as 50 percent in people with osteoarthritis, an expert suggests. The research, by Stephen P. Messier, PHD, at Wake Forest University, was presented this week at the American College of Rheumatology Annual Scientific Meeting in Chicago.Knee osteoarthritis is a common form of osteoarthritis and is caused by cartilage breakdown in the knee joint. Factors that increase the risk of knee osteoarthritis - including being overweight, age, injury or stress to the joints, and family history - can increase the risk of knee osteoarthritis.
Losing weight by monitoring diet is potentially one of the best treatments for controlling pain associated with knee OA. Researchers from Wake Forest University in North Carolina recently conducted a long-term study that evaluated the impact of weight loss with or without exercise in reducing pain caused by OA. The researchers also measured function and mobility in older, overweight adults with knee osteoarthritis.
The researchers conducted the Intensive Diet and Exercise for Arthritis trial that measured 454 overweight adults with pain caused by knee osteoarthritis. Participants were selected randomly to lose weight in 18-months by either diet restriction only, or combining dietary restrictions with exercise. These groups were compared to an exercising-only control group. The researchers set a weight loss goal for the diet groups of at least 10 percent of body weight and required the exercise groups to participate in one hour of low-to-moderate walking and resistance training three days a week. The researchers compared the changes between the groups after the 18 month trial.
