New York: Elite male athletes who participate in high-contact sports like football, soccer and rugby have a higher risk of developing knee and hip arthritis later in life than men who exercise a little or not at all, a recent study found.About 30 percent of athletes had hip or knee arthritis, compared to 19 percent who weren`t athletes."Regular exercise is important to health and well being," said Dr. Joseph Buckwalter, who studies osteoarthritis and sports medicine at the University of Iowa, "but certain kinds of exercise expose you to greater risk of injury."
