Knee Replacements on the Rise

by Associated Press posted Sep 25 2012 5:27PM
  CHICAGO (AP) - Just like baby boomers, older folks have seen a surge in knee replacements.
 
     The findings are from a study of more than 3 million Medicare patients who got artificial knees over two decades. The number of initial knee-replacements done each year more than doubled during that time. 
 
     There were nearly 244,000 in 2010. The study authors say the increase is partly driven by a desire to stay active and by obesity, which takes a toll on joints. The aging population and rising numbers of Medicare enrollees also contributed.
 
     The pace of growth slowed in more recent years - possibly because increasing numbers of younger adults have also been getting artificial knees. 
 
     The study appears in Wednesday's Journal of the American Medical Association.
