My knee is definitely answering my pre-op niggling thought "is my knee really *that* bad?" with "Yes!" It doesn't feel too bad if I'm not doing anything, but cleaning the house and doing errands the last few days--ow! Oh, and doing stairs, getting out of chairs.... I think because my first knee was so horribly bad compared to this one I have just a little tiny doubt==pre op jitters, I'm sure. Logically, I know the knee is shot and that my OS is fairly conservative. He wouldn't have recommended tkr if I didn't need it.
My OS is very willing to answer any questions and explain stuff and I'm pleased with the first knee, so really I am pretty confident going in.
