I had my right knee done Nov 9 traditional way, Dr Kissel at St Vincents/Andrews. He had done like 12,000+ knees. Nice guy too.
I am still going to physical therapy, went yesterday. The therapy and the exercises hurt, but are crucial to total recovery. I had a hiccup in my therapy...I managed to slip and fall, breaking two ribs. Cut the therapy back a little but ribs are healed now.
If you don't do the exercises/therapy you will end up in the hospital, knocked out, and the knee forcibly bent. I hear it is bad.
I'll have the left knee done in a few months
