The authors note the need for more research to leverage the potential of the risk calculator as a public health tool. They note that some risk prevention, especially related to injury, may be most effective for a younger population. “This study suggests that viewing personalized risk information for knee OA motivates subjects to be willing to change their exercise habits,” write the authors. “As the risk calculator intervention is brief, implementing further interventions after viewing personalized risk may allow subjects to act on this momentum.”
