No. Several surgeons have advised against. I should have asked why, as I see pros and cons, but I didn’t. My gut tells me to do one at a time. I can only imagine what steps, getting in and out of cars, showers, chairs etc are like with two simultaneous TKRs. I would also think that rehab is more effective if you have one strong leg to anchor the resistance exercises that are part of rehab. Perhaps someone else on this board has a more informed view.
