When I had my left knee replacement I wasn't able to work at longarming, recovery and range of motion was very slow to return..had lots of therapy..it was 2 very long months before I could even think of working. But when I had the right one done, it was a piece of cake, a couple of home therapy sessions then a couple more at the rehab facility and I was good to go..drove myself too. I was back to work at 3 wks.
Wishing you lots of luck! Hope it goes smooth for you.
