I know what IT band pain is like Don, mine started to get tight and knotted up after my accident, physio worked on them, and I still do stretches to try to keep them loose as possible, but when they are tight like that it plays into your knees, I also have moderate knee pain and saw an ortho specialist to have a look at the worse of the two. It pops when I squat, which is common in most people, but it snaps bad when I raise up, he told me it is not supposed to do that, signifying that something inside is not right. I don't want to even have an exploritory scope on it, could have and refused at this point in time, I can get by with it like it is, when it gets to the point I can't manae day to day then I will have it looked into, literally! My knees really do not enjoy stairs anymore, going down is not to bad SLOW, but forget going up... not happening

As far as what you need to wear going in, your doc will most likely give the surgeon a heads up on what is coming at him, but he may not, you could ask him about that if the time comes, but like you said, they are doctors and have seem it all to begin with. Most ofter they will have to have seen you for an evaluation and will pre-read your charts so I am sure he will see it one way or the other! Take care, and yes it sucks to get old! At 43, some mornings I feel 83 !
