@amytro @contentandwell Just my two cents but this is the best reply I've heard. Every TKR is different even when done on the same person, by the same surgeon, and at the same hospital. Another thing to consider is that you want enough time to go by to ensure that you did, indeed, pick the right surgeon. You don't want to find out that he used the wrong size implant on both knees! I had a friend who didn't find out until around 5 months PO since she and her PT team thought her progression ( or in her case, lack of) was mostly due to swelling and such. She was glad she waited and had the revision and other knee done by a better surgeon. But if you can by on a Cortisone shot or some other way to help you relieve pain, I would TRY to heal well on the first knee, condition the other, and go from there. Everyone says that the stronger you are the better the recovery but for me, that wasn't true really. Before my RTKR, I did an hour on the Elliptical 5 days a week, upper body weights 4x per week, and did a lot of walking. I was strong and healthy but this Thursday will be 7 weeks PO and my ROM is only 0/106 no assist and bend is around 113 with assistance from myself. (pulling while doing my knee slides) I was hoping to at least be 115 by now but no banana. So, my other knee will have to wait until next year. The verdict is still out on the surgeon as far as I"m concerned. So along with you insurance (make sure you have enough PT days left) there are a few things to consider before getting your other knee done.
