http://www.sacbee.com/111/story/1163046.html.....Schwarzenegger felt discomfort in his knee throughout the week and decided it was best to seek a medical evaluation Saturday, though he has not limped or used crutches, McLear said. The seven-time Mr. Olympia bodybuilding champion has long maintained a regular exercise routine that includes lifting weights and aerobic conditioning.
Schwarzenegger's most significant injury as governor came in December 2006, when he broke his right leg in a skiing accident in Sun Valley, Idaho. The injury required surgery and forced the governor to use crutches for two months in 2007. The governor also received 15 stitches on his cut lip after a motorcycle accident in 2006.........
