I was a lucky creature born without knee caps...This was a big problem to start...Bad circulation hindered my surgery....I, too, wear the elastic type stocking to the knee...I have been advised by the Therapist and Surgeon, that healing could be a problem...Many years of golfing did me harm...But it is something that my husband loved and it became a family thing...I guess a few 27 holes in one day did me in...
I hope that you find that your problem can be solved....Mine won't be, but it could be worse...
I wish you well....
