Spoiler:

well if you remember, tsunade healed sasuke up to perfect condition in like, 5 seconds. The only reason she couldn't do the same for lee was because the bone fragments and such were immbedded into his spine and arms or something like that. Regardless, the only way to fix it was a 50/50 surgical procedure. Now apparently it succeeded since Rock lee is up and about. But some people are saying "what the hell? how could he have gotten there so fast. he needs to recover!!!"

I think it stands to reason that if Tsunade healed Sasuke in a matter of seconds, she could do the same to lee AFTER the surgery was completed thus negating any need for a rehabilititation(sp?) time.

So in other words, tsunade just healed him back to normal after the surgery was a success.

That's just my guess.
