UNDATED (AP) — Joint replacement is enjoying a boom, thanks, in part, to Baby Boomers.

Doctors report more than 2 of every 100 Americans now have an artificial joint.

Among those over 50, it's even more common: Five percent have replaced a knee and more than 2 percent, a hip. Roughly 7 million people in the United States are living with a total hip or knee replacement.

Dr. Daniel J. Berry, chairman of orthopedic surgery at the Mayo Clinic, says "people are aware that they're a success" and are less willing to put up with painful joints.

He led the first major study to estimate how prevalent these procedures have become. Results are being reported at an American Academy of Orthopaedic Surgeons conference in New Orleans.

The number of replacements is expected to grow as the population ages, raising questions about cost, durability and replacing the replacements.
