In my opinion no, Tiger is an outstanding player...and yes he has come back from knee surgery before. However, this surgery is so severe that he will not be able to play for 6 months at best.
From personal experience (then again im no professional) recovering from an injury that takes someone that long to heal before they can think about hitting a golf ball, is the same as a football team going into a game with a strategy but no good trained team. The more he is unable to excercise that leg the more unbalanced it will become, because in the case of muscle memory: use it or lose it.
In closing, there is a definate possibility that he will not be AT THE PEAK of his game but he will probably still linger near the top of leaderboards next year until his regains his balance.
