I don't know crap about that surgery but I do know that diligent rehab is the key to success.

Stick with whatever rehab regiment they give to you and keep doing it, no matter if it sucks, hurts, etc. Pretend that your NFL career is on the line and that the only way back is your rehab....

I know 4 people who have had knee surgeries. 2 stayed on their rehab and are at 100%, if not better.

The other 2 were retards and gaffed off, or whined about their rehab and basically quit. Their knees still suck.

I'm going to guess that you'll still be in some form of a knee brace in all or most of July. Even if not, a rolling boat would seem to be a bad idea on a knee. A brace would probably be a good idea, regardless of what stage of rehab you are in at the time you are up there.

Oh yeah, talk to your doctor. Not the internet.
