Post TKR, due to a limited Range, inflammation and pain, I had an Arthroscopic Debridement, aimed at removing excessive scarring (Arthrofibrosis). As a result, I got even more scarring. I then had an Open Debridement which resulted in even more scar tissue. Doctors do not know how an individual’s immune system will respond. Studies show that 3-13% of those having a TKR will suffer from excessive scarring. I have now been advised to have a revision to a “hinged knee”. In this procedure, they remove your tendons, as they are an area that hold a significant amount of the scar tissue. The hinge then replaces the tendons. This was the recommendation from a Doctor at HSS in Manhattan (#1 worldwide in Orthopedics). I expect to have this revision surgery in mid 2025.
At HSS I was told that they are developing a test to forecast if someone is prone to excessive scarring. I read that the Mayo Clinic and several others are working as well to develop such a test. If this test had exist prior to my TKR, I never would have had it. I hope this helps.
