@melcpa86, you may noticed I moved your recent discussion and combined it with an existing discussion titled "Scar tissue after knee replacement." I did this so all of the members discussing scar tissue, or arthrofibrosis, would see your message and share their thoughts with you. I also had a really rough time with scar tissue after my knee replacement. I had two additional manipulations to try and break up the scar tissue and those were unsuccessful. Fortunately, after about 18 months, I was able to pop the scar tissue loose on my own. My initial movement after surgery was extremely limited, about 15-50 degree ROM. I eventually, through lots of pain, managed to get to 0-110 or so. I was not a candidate to have the scar tissue removed because they thought the risk of infection was not worth the 50/50 gain I may or may not get.

@melcpa86, here is another discussion on metal allergy you may find interesting too, https://connect.mayoclinic.org/discussion/need-tkr-and-had-positive-allergy-testing-bone-cement-and-metals/. If you don't mind me asking, is the lysis surgery something you are considering, or has it been ruled out by the professor?
