Your knee aches from time to time. Or maybe your fingers don't seem as nimble as they used to be. Could it be osteoarthritis?

Osteoarthritis, the most common form of arthritis, develops when cartilage, the flexible tissue lining the joints, deteriorates. As a result, the space between bones gradually narrows and the bone surfaces change shape. Over time, this leads to joint damage and pain.

Q. I occasionally use a brace on my knee because I have knee arthritis. Am I weakening my knee?

A. The benefit of a brace for knee arthritis is likely in the eye of the beholder. A brace can help improve the ability to perform certain activities, and for some people the compression and warmth of the brace relieves pain. However, medical research has been mixed on the absolute benefits.

Ask the doctor

Q. I take warfarin for my atrial fibrillation. I know it can increase the risk of bleeding. Is it okay for me to take ibuprofen for my arthritis?

A. In general, you should avoid ibuprofen—which is sold as Advil, Motrin, and generics—while taking warfarin, because taking them together may further increase your risk of bleeding.

Depression is fairly common among people suffering with rheumatoid arthritis (RA). Recent research suggests that depression may worsen RA symptoms and even make medications less effective. To date, the studies that indicate a connection between the severity of RA symptoms and depression have not been conclusive, so more research is needed. In the meantime, if you have RA and notice signs of depression, be sure to talk with your doctor.
