Let me know what is said... curious!!
I think still your knee should be better then what it is... Just a thought.
You had the muscle development there and there should be no reason that an athlete wouldn't recocver faster then the couch potato who may have had tha same surgery. I mean look at my mom she has had 2 full knee replacements. Her knees bother her at times, but her recovery and flexibility was regained within 4 months!!! And my mother has a LOT,, o.k. LOT of health issues and does not work-out. I just think your PT may have been what's to blame, or the doctor who did the surgery.... I have had some crappy PT. You have to be agressive in your own recovery. I think massage would have helped and can still help get more mobility back into that knee.
Sorry your dealing with this and your bad week
