Good afternoon @bushy, It appears that you are approaching this TKR rehab with a committed plan and some clinician supervision. I am going to share this link because it was clear and easy to follow. There aren't too many medical terms I have to look up and understand.

My TKR rehab plan was to follow my surgeon's directions. This was my 6th surgery with him and I trusted him 100%. Many of his recommendations are included in this blog. Together, we did a great job. He was so impressed with "our" progress that he took me and introduced me to his colleagues. I also did a video for him to give new patients. What a team!
