@damewocane From what I have learned here, and in a Facebook group about knee replacements, one of the most important things when getting one is doing a lot of research on the doctor. I did not do enough on the doctor who did my first TKR. My knee is OK, but not nearly as good as my second one.
The second doctor is phenomenal. When I first went to him and he asked he which brand of knee I wanted -- he uses two -- he also said that he believes the outcome depends less on the brand of the knee than it does on the competence of the doctor. I believe him. I did choose the knee that he was a developer of, Conformis, simply because I had heard so much good about it. I have not regretted it at all.
I live in southern NH but go to Boston for most of my medical issues. There is a doctor up here who does zillions of TKRs but I think he does so many that they are all just done the same way without regard to the needs of different patients. People either love him or hate him.
