You should look online at the mountain bike knee pads that double as a special knee brace
They are $$$$$$$ but apparently they have helped a lot of people, it only allows your knee to pivot the proper way.
Look on www.Hucknroll.com
EDIT: hucknroll merged with competitive cyclists
Just type in hucknroll and go to competitive cycle hucknroll side of the website
