James ... I am looking forward to hearing about your journey .... I am 14 months in but while not having the pain that I used to have my knee remains to be a work in progress .... I had 2 second opinions with doctors in the same group so although they took the Hippocratic oath ... I am suspect that they are all in cahoots. Next week I see another doctor from a different group. I had it all ... scrapping, dry needling, aspirations (negative), stimulus shock therapy, EMG nerve tests, and so on besides 6 months of PT ... My knee still feels foreign, and I still experience pain at night, and very tight all day but strangely, my ROM is good like 130 degrees +. I am going to check into the Patella Baja with the new doctor next week that was referenced in your thread as walking up stairs remains painful. I'm on the peloton 2-3 times a week. When I am inactive as I was last week due to an illness, my knee starts to stiffen up.
Like you I am looking for answers ... this is not what I signed up for as I was looking for enhanced quality of life at my age after my TKN but regretfully its been much worse.
