To expand on what I said previously... As someone who's had almost the exact same injury as well as had a major invasive knee operation, I can guarantee beyond a shadow of a doubt that he is healthier now, 3 months post op, than he was last playoff only 2 weeks post injury. After my major operation I was playing again by the 3 1/2 month mark. He has a far better rehab schedule and support system than I did so he has to be close to being ready to play if he isn't already. Getting back up to game speed is another thing entirely and getting back the trust in his legs stability and durability is again another thing to overcome.
There's too many assumptions for this though. The assumption that the degree of injury is the same. The assumption that there wasn't a setback in the rehabilitation process. The assumption that being able to play again for you is the same as being able to play for an NHL'er.
