(March 11, 2014) A new study finds that nearly 2 percent of Americans now have an artificial hip, knee or some other joint, and orthopedic surgeon Daniel Berry of the Mayo Clinic, who led the study, says, "They are remarkable numbers."
Roughly 7 million people in the United States are living with a total hip or knee replacement.
Berry led the first major study to estimate how prevalent those procedures have become.
The results were reported Tuesday at an American Academy of Orthopedic Surgeons conference in New Orleans.
