I had TKR on my left knee Dec 2013. Had poor ROM performance with PT and had MUA after 3 months. Recovery from MUA was most painful experience ever and totally ineffective. As time went on ROM got worse as scar tissue took over knee. Sep 2014 I had left knee revision to remove scar tissue and had right kne TKR. 3 more months of PT and right knee recovered much better than left as left knee once again grew excessive scar tissue. Dec 2015 I had a 2nd revision on left knee to remove scar tissue and surgeon said if this didn’t work he may have to replace remove appliance and start over. 3 more months of PT and ROM got worse with PT as scar tissue grew back again. ROM in left knee is about 70. As each day goes on pain increases with no improvement in site. Surgeon says that appliance is fine and there is no more he can do. Is there any solution to my problem. Contacted Mayo for help.
