Hi Ramone,
I had a second TAR related surgery May20 of this year. My initial TAR was Sep 19, 2019. It never reached a pain free level and some days got so bad I had to use a cane to take some weigh off my right ankle.
After complaining to my surgeon for over a year he went back in and following my surgery he related to me that he cleaned up channels( gutter space?) , replaced the plastic disc between the upper and lower Infinity devices and cleaned up some scar tissue.
since that surgery four months ago I have experienced much reduced pain that I would title it more like stiffness than the sharp pain that was emanating from deep within my ankle prior to my second surgery.
I am now walking several miles every other day with very minor stiffness, using my stationary bike , etc. Improving each week. You can see my complete story on this forum.
I hope your second surgery will provide you with the pain free ankle you deserve.
