It really didn't, from 2007-2009, he was still a very unpolished guy who was just less athletic. Maturity is what made him develop his skills, it would have eventually happened with or without the surgery. 2007-2009 Amare was = to or < Bosh, even when his numbers were mediocre at the beginning of the 2009-2010 season, he was a much improved player who was creating most of his shots for himself and stepping up on defense. People wonder why my opinion of Amare flipped so much from 2009 to 2010, it's because even tho the numbers might be similar, 2010 Amare was playing hard while 2009 Amare quit just as much as the rest of the team.
