I was reading back through and 6/11 is still a bit away. Don't try to be 'ready' for the therapist, if you know what I mean. Listen to your body and go forward.
I will tell you that with my last replacement my home PT (insurance mandated) we had a heart to heart. Well, more like I told her I wasn't doing anything except walking or heal slides and if she didn't like it she could leave. That was very difficult for me, but I did it. I said she would never touch my knee. She wasn't happy at all. I explained she should be happy because she was being paid to walk beside me half of a block and then back - that was it. She didn't see the humor! I held tight to my rules, she ask it visit if I'd changed my mind, nope. When (again insurance mandated) I had to go to PT I told them the same thing. I would ride the recumbent bike there but not do much else. The PT so wanted to force my knee down, but he didn't get the chance because I was brave enough to use my voice. I have no doubt that you can do the same. use your voice on what you will and will not do.
