Good luck to you...I'm new to this forum, so I hope I'm posting in the right place. Am scheduled for DOUBLE TKRs August 26. I never dreamed of doing them both at the same time until I met my new surgeon, and he feels confident I can do it, so I'm going for it. I'm 75, and not really athletic, so am trying hard to get as strong as possible before surgery. Just call me a wild and crazy gal...
