5/14/15 Patients who underwent knee replacement exhibited less cartilage thickness at baseline and, over time, greater lateral and location-independent femorotibial cartilage loss than those who did not get replacement, researchers said. Furthermore, location-independent analysis of change in cartilage thickness predicted future knee replacement. These were among the findings of a U.S.-European prospective cohort study published […]
