Im sorry to hear about this whole situation. I understand you are having a MUA . Remember to rest , elevate and ice and medication by the clock. However I am confused about the spacer part and infection. When will that be done. Same OS. ?? Same day as MUA ? As far as I know a MUA requires no cutting instruments at all. They basically put you under and bend your knee to break adhesions. In fact quite a few of them have been performed on fellow bonesmarties . Im still confused by your first thread , why did your OS insist on a immobilizer ?? You would think that would be counterproductive. Well Mick , best of luck , we will be here for you. Iceman
