16 months out on my right knee, 18 days on my left. Hard to remember now while I'm in the middle of my second one, but hands down the best thing I ever did for my knee arthritis which I've had for over 20 years. I was back to hiking after my first, and now with the second I can't wait to have to brand new knees. It is an amazing surgery but one of the most painful things I have gone through. There is light at the end of the tunnel. Hang in there! I am an RN and started back to work at 3 months. By six months it was incredible, and by a year, wow, felt like my own knee. Trust the process!
