I had a spacer replacement (increased size) about 4 years after an initial TKR which never seemed to work: bend was never great (about 90), PT didn’t seem to do much aside from cause pain though I kept at it, and always that unspoken charge that the knee was fine, the problems were my fault. I ended up with a pain Dr. and finally a different orthopod at a major university. This Dr. said my knee was unstable and suggested sx. So I had an open partial revision at which he switched up my spacer and cleaned out some scar tissue. Knee was bent to 125 while under anesthesia. The op report sounded pretty uncomplicated. LOTS. of pain immediately post op, PT was very painful but eventually things settled down and I was fairly pain free (off pain meds) for about 2 years after which the pain has returned, pretty much to original level. So now my bend is about 90, my pain is about 6, I go to the gym 3xweek for a gentle workout but my operative knee is pretty useless. I am profoundly affected by the weather. Was the spacer replacement worth it? Probably not.
