Replying to Tendonitis

Ok so I somehow got tendonitis (jumpers knee) in my right knee. It's the tendon right below the knee cap that connects the knee cap and the shin. (If I remember right.)

I've heard that if you let it go long enough without doing anything to help it that you will need surgery. I have a knee brace for it.

Has anyone else had this? Did you ski normally with it? Did you wear a brace while skiing? Should I take it easy on it just to be safe?
