Other causes of knee pain can include being overweight or obese, which increases stress on the knee joints and also increases risk of osteoarthritis.
- According to the Johns Hopkins Arthritis Center, even 10 extra pounds of body weight can place a significant strain on arthritic knee joints.
- A force of between three and six times one’s body weight presses into the knee when you’re walking. That means for every extra 10 pounds you weigh, an additional 30 – 60 pounds of force is put on your knees with each step!
- Data from the first National Health and Nutrition Examination Survey (HANES I) demonstrated that overweight women have nearly 4 times the risk of developing knee osteoarthritis compared to non-obese women. For overweight men, the risk is nearly 5 times greater!
- Losing as few as 11 pounds can reduce the risk of developing knee osteoarthritis by 50 percent in some people.
- Severely overweight people undergoing knee joint replacement may be more likely to suffer from failure of the replacement joint.
These statistics point to the same result: Controlling body weight is key to slowing the progression of osteoarthritis in weight-bearing joints such as the knees. More on Arthritis, Obesity and Weight Loss.
