Have you seen a reference to microfracture surgery that appears to be different than what the TP laid out here?
I haven't actively looked. I remember during the month he was resting his knee in camp that he was seeking other medical opinions and it was brought up again. I found the article referencing ESPN and Broussard, but if he isn't a good source you can disregard. I remember that article from TP though and it did a good job summing it all up. It's funny though, if you look at the next paragraph after the ones you posted..
"Ultimately, Gordon underwent an arthroscopic procedure Feb. 14 that, he said, cleaned out loose cartilage particles, enabling him to return to play seven games in the final two weeks of the season."
So all of the doctors in New York and Indy were wrong and rest wasn't enough, right?
