Osteoarthritis: Where Does It Hurt?

 Where Does It Hurt?

In most cases, osteoarthritis develops in the weight-bearing joints of the knees, hips, or spine. It's also common in the fingers, thumb, neck, and big toe. Other joints are usually not affected, unless an injury is involved.

What Causes It?

Every joint comes with a natural shock absorber in the form of cartilage. This firm, rubbery material cushions the ends of the bones and reduces friction in healthy joints. As we age, joints become stiffer and cartilage is more vulnerable to wear and tear. At the same time, repetitive use of the joints over the years irritates the cartilage. If it deteriorates enough, bone rubs against bone, causing pain and reducing range of motion.

Risk Factors You Can't Control

One of the major risk factors for osteoarthritis is something none of us can control – getting older. Gender also plays a role. Over age 50, more women than men develop osteoarthritis. In most cases, the condition results from normal wear and tear over the years. But some people have a genetic defect or joint abnormality that makes them more vulnerable.
