@DEM8869 ---there is no "schedule" for recovery. There is no, "At this time, you should be able to do this..." Your PT is wrong and your PT is wrong to bully you. The more pain that is created during these sessions, the slower your recovery will be---and more frustrating. We are all different, and our surgical recoveries are different, too.
For the most part, a TKR recovery takes a lot longer than we would like it to and a lot longer than we are prepared for. It took me six months to get close to 80%-85%. It was not until eight months that I was around 90%-95%---and I gained ROM well after the one-year anniversary of my BTKR surgery.
Relax, and be patient. Set limits for your PT---and do not let them cross the line. If they do, fire them.
This is not about "no pain, no gain"---but rather, "no pain, more gain." The more you let somebody inflict pain on you---both physical and psychological, the slower and more frustrating your recovery will be.
Please, please, let your PT know that you are upset with her and that you will not allow her to hurt you again. Take every thing to the point of discomfort only, ice and elevate as much as you can.
