C & P exam

I was rated at 30% after my replacement, I just completed exam for an increase. This is what the Dr reported. Progressed/worsened, functional loss or impairment, frequent effusion of the knee, crepitus, range of motion contribute to functional loss, flexion 85, Extention 20, Evidence of pain during: weight bearing, non weight bearing, active motion, passive motion, on rest, non movement. Total knee replacement residuals: Chronic residuals consisting of severe painful motion or weakness. I looked at the ratings for flexion, extention, and pain after replacement there are so many areas to be rated I got confused. Can anyone comment on what rating you can come to with this report?
