Hi Margaret,
I'm glad the TKR knee is doing well, apart from the quad leg. Has that improved at all? Sorry the other knee is causing you pain in the night, though.
I get my 2-year check in December and I'm still happy with my TKR. It still gets stiff overnight and if I sit for too long, but that stiffness soon goes as I walk it off. My non-TKR knee is deteriorating, too. My OS offered me a PKR last year, but I've said I'll wait until a TKR is indicated. If it progresses like the TKR knee, it will be about another year. We shall see, when I have the check X-Rays in December.
Best wishes,
Caryl
