It says this was posted 5 years ago. Did you have the surgery? I had right knee replaced and exactly one year later changed doctors because I still had horrible pain. The new dr. said "Ok Billie now you need both knees replaced because this one did not take and you have been using the other knee to sort of replace this one that you had done." I said OK do them both at the same time because I would never come back since I already know what it involves." He sent me home and said think about it for a week and come back because not many people have both done at the same time. He even said he did not like the idea of doing both at the same time. Well, I thought about it and decided I would go for it (both at the same time). I have never been so happy with a decision that I have made. It was hard because I didn't have a leg to stand on as one nurse said. I was in the hospital for a little shy of a week and then went downstairs to Physical Therapy and was there for about 3 weeks, maybe less. Its been 3 years now and I have only had one problem and that was today. My left knee buckled. I would not advise everyone to have both done at the same time, because it is a tough way to go. I was in therapy after I got home also. I am curious if you had it done. I was 74 years old when I had it done. If you would be so kind as to let me know what your decision was and how your results came out. I have not talked to anyone else who has had both done at the same time. They always say how could you do that? It was tough but I am so happy with my results.
