Thank you very much for that. I guess I'm just sensitive because if one more person tells me "I never heard of that," or "why is it taking so long for you...I know someone who runs a marathon....." Etc. Believe me, I want that to be me. I did all the work and continue to exercise the knee following the instructions from physical therapy which I did until four months after surgery. I still do my exercises every day. My very first surgery was botched and they did not use glue (according to my second surgeon) and the knee started to literally bow inside my body. So the revision was successful but according to my doctor that knee will never be the same since they have to use such a large implant with revision and they cut more bone in the process. I accept that, but I had high hopes for the second tkr. I guess I'm just waiting for the magic to begin:) Thanks again for your kind words.
