@gator1965 You have been issued with a "formal written warning"? Is that from your medical team or your work? If from work I presume it must be that if you do not get back to work you will be terminated. I'm sorry if that is the case, and I hope you can manage to keep up with your job despite the pain.
My doctor is doing a small procedure on me, probably next month, to go in and get rid of some of the adhesions that prevent me from having better flex. It's called "arthroscopic lysis of adhesions". Does that sound like something that could help you? The procedure was described as follows by the doctor's NP -- "goes in with a small camera and a small tool that burns the scar tissue away". This is an outpatient procedure and you can immediately put your weight on the leg. The incisions are only about a half inch long.
I do not have pain, just poor range of motion. He said I could never get along in Japan with my lack of flexion. I do get along here, but it is difficult to do certain things so I hope I will gain a bit more flex from the procedure.
I hope your doctor, or another if you get a second opinion, can give you some help.
