(POOL/CNN) - Former President George W. Bush is recovering from a second partial knee replacement.
A spokesman for the 68-year-old says this time surgery was performed on Bush's left knee.
The weekend procedure in Chicago comes just weeks after Bush had the same doctor perform a partial knee replacement on his right knee.
Bush's rep says the former president and his wife headed back to Dallas Monday, and he expects to be Back Mountain biking in a few weeks.
