Hi sorry to hear your still having issues…. I am almost year out and I am going for revision on the 28…..I had difficulty getting flexion and keeping it ….. I had mua at 6 weeks with no results …. My dr blamed me not working hard enough blamed arthritis even my migraines which have been under control…..needless to say I got second opinion hence revision being done my knee slightly to big reason I could not get flexion….I do mfr since 3 months out of tkr it has helped so much for tightness and enabled to straighten my leg almost fully ….. I am so disappointed in my original tkr dr…..with that said never hurts to seek second opinion ….I hope you start feeling relief
