(Associated Press) – It’s not just grandma with a new hip and your uncle with a new knee. More than 2 of every 100 Americans now have an artificial joint, doctors are reporting. Among those over 50, it’s even more common: Five percent have replaced a knee and more than 2 percent, a hip. “They are remarkable numbers,” said Dr. Daniel J. Berry, chairman of orthopedic surgery at the Mayo Clinic. Roughly 7 million people in the United States are living with a total hip or knee replacement.
