You go girl, my right knee extension was at a 4 when I had my 2nd surgery in May, the ROM was only 105, but My left knee became worse from using it as my anchor leg, So yes, I did think it kept my right knee from healing up properly , one night I could not even stand on it and was so happy that I was already scheduled for the surgery , Lets face it, it all sux, I still miss my old legs, they were awesome, but that ship sailed. I am sure that I did the right thing doing both surgeries - it is only going to get better every month from now on-My right knee finally got to a 0 when I spent a few months walking on it- my ROM is improving whenever it’s not swelling, I honestly don‘t worry about extension or Rom anymore with either knee- I took a 2 week break from PT and am going back tomorrow - just for the massage and bike riding- I accidentally did 20 squats to the ground and got my new knee from a plus +9 extension to a minus -2 the only benefit from giving myself 2 weeks of pain & swelling, LOL
i will be sending you prayers and wishes for your successful surgery tomorrow.
Here is a pic of my bionic knees taken last week. Still creeps me out a bit, but I have made friends with them.
