With my experience my revision was total success…. From the time I awoke from surgery it felt different in a good way ….. I like you was not looking forward to going through all the pain and therapy for weeks ….yes it was painful but difference was I retained every degree I pushed for ….. even now still do water exercises and land I think I always will ….,I have had one or two setbacks but my flexion is still 100 and I hope to get more… before surgery they measured I was 60 …. I am very pleased with revision I hope your goes just as well….good luck there is always hope ….if you don’t give up
