They say if fall down, could tear something loose an would have to start over, infection sounds nasty if happens

Dave, focusing on the negatives is the worst thing you can do right now. I'm 7 weeks post op from a full knee replacement. Wish I had all this advice going in. I had a spinal block never felt it, I remember the mask getting pulled over my head and then I was waking up. Take the meds as directed for the first week. Then you can reevaluate how much and how often. My oxy dose was one every four hours, at four days I pushed it to 6 hours then stopped the oxy at 7 days and could manage with Tylenol and Celebrex after that but I always took one 2 hours before PT just to be safe. Look into renting an ice machine, it's a bladder that has cold water circulating through it. wear it all the time you're sitting and especially when sleeping. Make sure you have a compression sock also preferably a full leg one. A recliner for the first 5 nights is a big plus. PT is a must and do what they tell you when your home. You don't have to overdo it, walking with a walker around the house for the first week will do a lot for you. Most of all be patient things will take time, Don't put yourself in a position to fall watch where you step stay on the flat and level. I was beaver trapping at 6 weeks, but had to really pay attention.

I have a friend who had two bad knees. He said it went so well with the surgery and the recovery on the first knee, he decided to do the other knee a month later. He said he wished he had waited a little longer on having the second knee done, as it slowed down the healing a little on the first knee. But, now all the pain is gone and he's glad he did it.
