I hesitated responding to your first post "Total Knee Repair Revision: A Success Story" back in Aug 4,2022 because I didn't want to dampen your optimism. Your story mirrors mine. Of my three TKR's the revision appeared to be initially the most successful with less pain and faster recovery (short term), and allowed me to go to PT in two days following surgery. I made steady progress for four months when improvement stopped and started to go downhill.
I'm seeing my Ortho again tomorrow post my Dec 26, 2023 surgery. I was always curious why he never commented on me requiring a cane, but tomorrow I'll mention it. I did't want to go on about me, but I just wanted to let you know you're not alone in this TKR nightmare.
