A new study by radiologists found that middle-aged men and women who do lots of exercise, and specifically athletic activities like running and jumping, may be causing damage to their knees and putting themselves at greater risk of developing osteoarthritis.
 
Chritoph Stehling and colleagues did the study and presented it on Monday at the 95th Scientific Assembly and Annual Meeting of the Radiological Society of North America (RSNA) being held from Nov 29 to Dec 4, in Chicago.
 
Stehling is a research fellow in the Department of Radiology and Biomedical Imaging at the University of California, San Francisco (UCSF) and a resident in radiology with the Department of Clinical Radiology at the University of Muenster in Germany.
 
Osteoarthritis is the most common form of arthritis and affects around 27 million American adults as per the estimates by the US Centers for Disease Control and Prevention (CDC).
 
The three features that are occur due to osteoarthritis are: damaged cartilage, bony growths around the edge of joints, and mild inflammation of the tissue surrounding the affected joint.
