But how do you know what is the rights advise? The lack of consensus on this issue is very concerning. I did not progress after my replacement. I had very aggressive PT 3x/week, "no pain no gain:" treatment for sure.
After 6 weeks it was clear that I couldn't bend nor straighten my knee to the degrees of "normal".

I ended up getting the MUA (manipulation under anesthesia) to restart the process. More aggressive therapy for weeks on end...

Just over a year out from my MUA and I give that knee a "C+" rating. I don't know if I could go through all of that again for knee #2, which is acting up big time.

I am a very healthy 65 y who stays very active. Walking and hiking are pretty good. That new knee limits what I can do with it though- wouldn't want that limitation on knee # 2 as well.

So many variables on patient and surgeon for a successful outcome; but I had heard a size of my component would be reduced second time around (!!!)- so did that contribute to issues? Surgeon always says no way.

I HATE that the only way I can get the knee going every day is by starting with an NSAID, warm up on upright bicycle, floor stretches, heel slides, weights... every day, to get her moving. When I didn't do this when on vacation, I lost 20* in flexion, making stairs very uncomfortable. It has taken me about a month to regain that. Very disconcerting that this is part of my daily routine now. My Dr. said this was normal.
