How long does a knee replacement last?

ANSWER

Doctors first started replacing knees in the early 1970s. Back then, surgeons said the new knees would last about a decade or so. Today’s implants will last 20 years. By 2030, it’s estimated doctors will perform about 450,000 total knee replacement operations a year.
