Sorry to hear you have been through a lot ….Unfortunately yes I had tkr in august no bend just like yourself. I had mua 6 weeks after tkr …. You know mua you have to do pt everyday for a week we’ll we ended up doing more for swelling than bending … so it did not work for me….I am 8 months out now still struggling with bend I am at 70-75 now….. I know you must have read on these pages about mfr release… well I started that and water therapy like at 9 weeks…. That is how I have gotten to where I am ….. without mfr I think I would be in rougher shape now… I go for second opinion today I still have pain and get swollen every time I try new exercise or walk ,stand to much….. if you can try water therapy it may be very helpful…. I found water therapy place in my area called dr he sent script….,was pretty easy . My prayers go out to you I hope you find some relief….
