Knee replacement surgery can be an effective way to treat osteoarthritis. But according to one review, it may pose additional risks for obese patients.

Diet and exercise are two things that heavier adults are told to consider when seeking relief from pain in the knees. With osteoarthritis, exercise by itself might not be enough to reduce the stress placed on those joints.

The link between being overweight or obese and other health issues is clearly established for conditions like heart disease, cancer and diabetes. But a person's weight may be related to migraines as well.

Excessive pounds can put added pressure on the joints of obese individuals. Man or woman, that added pressure may contribute to arthritis. But new research suggests that obesity may have a bigger impact on arthritis in women than in men.

Extra pounds from fat can stress the body in a number of ways. For older adults, excess weight can rub the knees the wrong way.

Osteoarthritis, known as “wear and tear” arthritis, affects more than 20 million people in the US. Avoiding undue stress on your joints early on makes a huge difference in old age.   

Being "big boned" as a kid is one thing. But having big bones doesn't mean the bones are strong and dense.

One major consideration when undergoing knee replacement surgery is whether the new knee will actually be an improvement over the original knee.
