Risk Factor - Obesity

Risk Factor - Obesity

Studies have consistently shown that being overweight will increase your likelihood of developing knee osteoarthritis.  Obesity is a clear risk factor.  Being overweight increases the load placed on the knee joint.  This increased stress could hasten the breakdown of cartilage.

Scientific estimates put the stress on a knee joint at 3 to 6 times a person’s body weight while walking.  The more you weight the more stress you place on your knees with every step you take.  Some studies have also shown that being overweight increases the likelihood of developing osteoarthritis in the hands.  This suggests that circulation may also play a role in how osteoarthritis develops.

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.
