Your story mirrors mine, as I also had my first TKR (left knee) in 2018 and followed up with a revision in 2023. It is probably the worst decision I ever made. My right knee turned out better but not 100%. I walk with a bad painful limb and a constant awareness that I have a prosthetic knee. When I'm asked about my quality of life I think to myself they must be kidding when my mobility is limmited. A video of me struggling to put on a pair of pants will put that question to rest.
One day they'll look back on today's TKR and say "they did what," somewhat how we see Civil War surgeries.
For those that are satisfied with their TKR be thankful.
