I'm sure that it's entirely possible - I've never even heard of it until I started browsing the forum, so I'll definitely check that out. It's pain/stiffness on the outside of the knee ... does that sound about right?
For me it is the inside of my knee on the top, not the outside. I don't know if it could cause problems with the outside or not but am sure that someone here will say something if they have had that happen.
