Using my weightlifting knowledge, i would say that you probably want to widen your stance. If you want to be technical about it, by widening your stance your making it so that your knees dont travel as far forward, not passing your toes.
When you knees travel over your toes, it increases torque on them.
Also, you may want to try riding with more of a "cowboy stance".
When doing squats, weightlifters try to avoid there knees buckling in, similiar to keeping your knees facing out when cowboy stance riding. Im not an instructor but im sure one of the guys can explain cowboy stance better than i so im gonna leave it to them.
