Physical activity and age-related biomechanical risk factors for knee osteoarthritis

Knee osteoarthritis (OA) is a highly prevalent disease leading to mobility disability in the aged that could, in part, be initiated by age-related alterations in knee mechanics. However, if and how knee mechanics change with age remains unclear. What are the impacts of age and physical activity (PA) on biomechanical characteristics that can affect the loading environment in the knee during gait? Three groups (n = 20 each, 10 male and 10 female)...
