The comments on noises coming after TKRs are interesting. The only thing I've noticed is that, when standing, I can push my patellas like buttons and they make a small clicking noise (with whatever they're hitting, probably the femoral prosthesis).

My surgeon said noises can develop early or later, can come and go, or stay. My knees feel so incredible good after TKRs, I don't care of they play music. No more bone on bone is a luxury at my age!
