Update:
So far, PT pretty much sucks. The knee is tight and hurts when I bend it much. The immobilizer that I have to wear is uncomfortable and is generally a pain in the butt. But, I am seeing some progress with mobility in the knee. I have been able to work through the pt without narcotics so far. It sucks, but it's doable.
PT is the critical phase to get the best recovery - not just for the two months you do it at the PT clinic but also the 6 months to a year thereafter. Follow their instructions to the letter and don't do anything you are not supposed to do.
Get an exercise bike and once you start doing the bike at the PT clinic double down on that at home for the next 12 months for the best result.
Good luck!
