Knee OA

Knee OA & Obesity

Researchers from Boston-based Brigham and Women’s Hospital used a mathematical model to analyze data at a national level that looked at occurrences of knee osteoarthritis, obesity, and conditions like cancer, heart disease, diabetes, and lung disease.  They were trying to figure out how knee osteoarthritis and obesity affects longevity and quality of life.

Older Americans suffer from both obesity and osteoarthritis of the knee.  These are common chronic ailments that affect people over 50 years of age in our country.  It is estimated that decreasing obesity rates could decrease total knee replacement surgery by over 269,00 cases and could save somewhere around 19.5 million years of life!

Estimates range from 30 to 60 pounds of force is added to every step a person takes for every ten pounds they are overweight.
