I found work on balance in PT very valuable. Lots of muscles you realize you either haven't been using properly due to the bad knees and/or need to be conscious of as you recover.@Slainte wow, you are doing great! I still take ES Tylenol 1000 mg 2times a day, and the PM at night. I have always had sleep issues, so not just the knee thing. i had another PT today who mostly worked on balance and did some massage, muscle release, so it felt good then but pretty sore now. She didn't check my ROM.
