For patients who have osteoarthritis, aching knees don't always seem compatible with physical activity. But a new study shows that exercising may actually add healthy years to a patient's life.

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.

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.

Your body weight and your job may be putting considerable pressure on your knees. This pressure could lead to a medical condition called knee osteoarthritis.

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.

Muscle strength is key to helping wobbly knees become more stable. And you have to exercise to get that muscle strength. But whether or not the exercise focuses on the knees might not matter.

While walking has a low impact on the body, and is convenient and inexpensive to do, few adults are actually doing it, particularly those with arthritis.

Osteoarthritis of the knee can get in the way of physical activity. For people with this condition, strong muscles may be the key to maintaining strong physical function.

If you are overweight, those extra pounds could be adding to the wear and tear on your knee joints. Gaining more weight could make knee pain and function even worse.
