OsteoArthritis is the most common form of arthritis. It relates to the changes in cartilage
and bone of joints. The changes could lead to pain, stiffness, swelling and limitations
in mobility. Obesity, joint injury, and muscle weakness are some of the risk factors
for OsteoArthritis. OsteoArthritis can affect any joint, but most commonly it occurs in knees, hips, lower
back and neck. Sometimes, small joints of the fingers, the base of the thumb and
the great toe can be affected by it. As many as 21 million people in the United
States have OsteoArthritis. Some of them may even be without symptoms.
