I think it's too early for you to have MUA accordingly to our collective experience. Maybe you want to have one, but you are progressing albeit slowly. Even a couple of degrees a week adds up (10 weeks = 20 degrees)! I personally think you should wait and reconsider in September and to also stop the "hard work" part of PT that is pushing your bend. On an inflamed knee, that can and will backfire. The other thing about MUA at this point is the re-injury of newly injured soft tissues from your TKR. That tight clenchiness of your knee is swelling due to that original injury. Josephine can explain it better than I can.
