DALLAS -- Former President George W. Bush is back at home after undergoing knee replacement surgery.
It was an out-patient procedure in Chicago, and he returned to Dallas yesterday, according to his office.
They say he is recovering quickly. Just a couple hours after the procedure, he was able to walk up and down stairs.
His knees started bothering him years ago during the presidency. He had to give up running and switched to mountain biking.
The 67-year old also had surgery in August to have a stent placed in his heart to help with a blocked artery.
