Sounds like me. My PT told me that he was hitting a “hard stop” in trying to bend my leg. He said that he could tell that he was not making progress and recommended suspending PT, to which multiple surgeon agreed. This was because of excessive scar tissue. After that, an MUA, arthroscopic Debridement of scar tissue and an open Debridement for the scarring, my surgeon turns me loose, saying that we are sorry for how it turned out. HSS in Manhattan (for second opinion) recommended revision to a hinged knee. Because of the scarring, they remove all tendons, which are a major area of scarring and the hinge takes on the function of the tendons. I couldn’t use HSS (#1 orthopedic hospital worldwide) because they do not accept insurance. I am trying to get into The Mayo Clinic but have been turned down, as they say that they have more requests than they can accommodate. I am appealing that. It’s a long, painful and frustrating road. I only wish that I knew that I would be one of the ones affected by Arthrofibrosis ( excessive scarring…genetic) and I never would have had the surgery to begin with. Hang in there. I just think of others who have problems a lot worse.
