TKR #2 in 3 days, 12/2/20. #1 was roughly 3 months ago and recovery/rehab on that is going well so, since I am just aging in place here, decided to proceed with #2. Actually, both knees have been bad; I need both replaced to return to active hiking. I used to do a lot more, but I will be happy if I can just go for several hours in the hills.
Having done one recently, facing the second is emotionally easier. Knock on wood, but I do hope this one goes as well as the first. Some other medical issues have cropped up to complicate things, but they will have to wait.
Side note: while working on strengthening I always included both legs. As I was taking up the weights for leg lifts--for example--my knee with the original equipment suddenly became the bigger problem so I have backed off from challenging that leg at this point.
