No he didn't. They left a tiny piece of cartilage floating around in his knee after the first surgery. When he started doing physical activity again, it bothered him, he got an MRI, and they identified the problem.
I do agree though, that it was probably silly to think Votto could play a few innings in two minor league games and be in playing shape. More likely he'll be ready after seven to ten games. The problem with that is, there are only so many minor league games left.
