@amberpep If you are happy with the results then you should return to the same doctor. Do you know what type of knee he does? It helps if we are confident of our doctors I believe.

There have been many advances these days with the MAKOplasty (robotic surgery) and the Conformis knee, maybe he is doing one of those now too, they both have excellent results. My knee is a Conformis and I do personally know a couple of people who have robotic - @debbraw has had it.
Hopefully, your knee will not progress to the point of needing another TKR.

Since around six weeks I have had virtually no pain or discomfort from my Conformis knee except very minor, more like fatigue, when I overdo it. I have walked for very long distances with no problems at all though.

You are in a neck of the woods that I am familiar with -- I have stayed overnight in Frederick on our way to Fredericksburg when my daughter was in college so I am somewhat familiar with the general area there and also around DC because she worked and lived in DC/Arlington/Alexandria for a while after college.
