Former President George W. Bush has successfully had a partial knee replacement in Chicago. Bush spokesman Freddy Ford says Bush had the procedure Saturday and returned home to Dallas Monday. Ford said in an email Tuesday that Bush was "doing great" and was able to "get up, walk around, and go up and down stairs just a couple hours after the procedure."
Bush is known as a fitness buff. Since leaving the White House the 67-year-old has hosted an annual 100-kilometer mountain bike ride in which he rides along with those injured in wars in Iraq and Afghanistan. He participated in the ride earlier this month at his Crawford ranch. He had a heart procedure to ease a blocked artery in August.
