Update to to my revision story … was not a success … two years later right back where I started … Dr seems to think it is surrounding tissue that is tightening and pulling back to this same extension and flexion … no other explanation he even went down two sizes should have never went back to 70 flexion baffles the Dr …. So no more surgery’s he said it would just go right back where it is now …. So I am always aware of my knee and pain , just have to find way to live with it so far only taking Motrin and using osmo patches for swelling ….. I bought PEMF mat use it twice day , still going to chiropractor for laser does help with pain ….i wish there was a test prior to having knee surgery to see how your body would respond to it, maybe in a few more years they will …..to all that are going to have revision hope it works out better for you ….this tkr journey test your mind, body and spirit and to tell you the truth right this second I am tapped out …. I have to reboot find what works …
