What Is Subchondral Sclerosis?

X-rays and imaging studies are used to help diagnose osteoarthritis. Actually, images are a big part of the diagnostic process -- along with a patient's medical history and physical examination.

For example, what is subchondral sclerosis? That's something commonly seen on x-rays that show osteoarthritis. Let's break it down. Subchondral bone is the layer of bone just below the cartilage. Sclerosis means thickening. So, what's the significance of subchondral sclerosis when seen on an x-ray?
