On September 13th, 2007, during preseason before his rookie season, he underwent microfracture surgery to repair his right knee. He would miss the entire 2007-2008 season.
Oden managed to return from his first microfracture surgery only to have Andrew Bynum land on his foot on October 28th, 2008, injuring it . He would miss only two weeks, though.
Then on February 13th, 2009, he bumped knees with Corey Maggette and chipped his left patella . It was the first injury sustained to his left knee and he missed three weeks due to it.
He recovered from that and 2009-2010 was set to be his year. He was looking very much like finally the player he was supposed to be. Then on December 5th, 2009, he landed without contact on his left leg, and badly fractured his left patella . His recovery was projected to take him right up until training camp of 2010.
After missing training camp, preseason, and the start of the regular season , and after saying he wouldn’t return until he was 100% healthy but that he could still be an impact player and that he was not a bust, it was announced on November 17th, 2010 that Oden would undergo microfracture surgery on his left knee and would miss the entire 2010-2011 season.

Oden has played a TOTAL of 82 games since he was drafted…..compared to Rose who has played over 270 in his four seasons already. Again, DUMB A$$ comparison, even if you WERE trying to make a joke, but failed miserably! Thumbs down me all you want but I proved my point! I’m out!
