Thank you all for your reply.
By the 3rd day of intense pain and swelling in good and bad knee I went back to PT. Another 2 hr session but it was all about stretching and lymph massage, ice massage 2 times, tens unit and leg press.
They said pain from pt should only last 8 hrs. While on the leg press they stopped me between reps to evaluate how my knees were doing. The good knee was popping and right surgical knee was burning. So that was my limit.
Today I am able to do my "normal" pt at home and am not having to pack it in ice. So hopefully I will continue to trend upward.
This is month 2 of PT. Looks like I am in for a long recovery. I see my OS in 6 days and have a ton of questions.
Again, thank you all for your reality check and advice.
