I think PT should be about more than range of motion. You might want to consider the possibility that the therapist isn't good at their job. I wasted months with a bad one, made very little progress until my doctor sent me to a different one.
You should find someone to video you while walking in a well lit area to show the doctor. And stress to him that you are not recovered -- you cannot walk. If it's not addressed now, you will develop all sorts of other problems with your knees, hips and back and you probably won't have that treatment covered by worker's comp.
