Good luck on Tuesday! You only have three days left, so make sure you have all your recovery aids either in place, or planned for, as posted above by Jockette and Benne, and have plans for after surgery meals. What I suggest is to keep as busy as possible to keep the nerves at bay and make the last days go by faster. We're here if you have any more questions, and will see you on the other side.
I don't know if you live alone, but in preparation for my recovery I got a full tank of gas in the car so my first drive would be simple. I also moved my car so it was easy to get in it. I did practice runs pretending to have a straight surgery leg. I tried getting into the shower and sitting on the toilet. I also pretended I fell (not that I planned to) and figured out a way to get up without anyone helping me. It made me feel prepared rather than overwhelmed so going into surgery wasn't as scary. I trusted my surgeon and that was huge. You'll get there. Good luck!
Read through everything and remember to breath. Also keep your cell phone with you. That way you can call someone to help you if needed or just to chat. Also I find music to be very relaxing and having your phone you can find YouTube, Pandora or any number of places to find some music to help calm you and your knee down.
Precook or prep and freeze meals you really like. Consider where you want to spend hours every day resting, elevating your leg, and icing it : some of us find it intolerable to be in bed for long at first so consider a recliner or a sofa high enough to get on and off and a stack of plump pillows for elevating.
