@comeoutdancing The hospital PT had me go up and down 2 steps in a corner room they use. I managed that, and that was all they needed to ok my release. Believe me you are in for major pain and discomfort. Good you have a reliable caregiver. I had no one.
You will be given meds to control the extreme pain, and it is imperative you not lay in bed all the time. Walk around a lot when you get home to help your leg and also prevent blood clots.
I doubt you will be dancing any time soon. From my experience it takes many months to get back expected strength in that leg. My surgeon who is one of the most revered in this area told me up front it takes 6 months to a year to heal. I’m at 6 months and still missing the overall strength I had pre surgery. My 2 hip replacements were a piece of cake compared to TKR.
