Aside from all the risks, performing both surgeries at the same time can make it an extremely long and difficult recovery. If you were to have them both done at once, you'd basically lose all ability to walk for months while you're waiting for everything to heal. At least with doing one at a time, you'd still be able to use crutches or a walker while you heal to get around. I know you say you're hurting now, but it can be a much more difficult road if you get both surgeries at the same time.
Not to mention the cost of the surgery itself. It can be extremely expensive to just have one TKR. I know my grandfather was looking at costs when it came down to doing a single or double TKR. Just to give you an idea of what he was looking at, I found a cost estimator that might really help you understand what you could be facing with just one TKR. You can input your zip code and it will locate costs in your general area for everything. You can even customize it to your age and pre-exisiting conditions, it's an excellent tool for finding out knee replacement costs. I hope it helps, good luck dear!
That sounds awful and I can understand you're concern about having one knee replaced and having to wait to fix the other. I also understand the doctor not wanting to do too much at once do the risks of the surgery. I looked up some of the complications of total knee replacement for you and here are some of the risks and complications. I would suggest letting your doctor do one at a time because if you were to do both at the same time you're more likely to suffer the complications. I wish all the best to you.
