Markers for OA Discovered

In the past, the only way to diagnose osteoarthritis (OA) was through X-rays, computed tomography scans, or magnetic resonance imaging. And those methods have been far from satisfactory because it takes months before any changes in cartilage become evident.

In a new study published in the October issue of Arthritis and Rheumatism, researchers discuss findings demonstrating that OA causes changes in the levels of 2 markers of collagen production and metabolism in the blood and urine. These appear to be biological markers for cartilage synthesis and degradation that are present in OA.
