No @timb - you don't sound like a fatalist. You do sound fed up with what you are going through and I can't blame you. I don't know how to begin to weigh the pros and cons of having arthroscopic scar tissue removal. If you don't mind sharing, did the same doctor do the original TKR and the replacement to get the right size implant in? I'm wondering if there is some value in getting another opinion before you have an additional surgery - especially since you sound kind of conflicted about it anyway.
