After 3 operations on my right knee, it now permanently points to the outside quite a bit.

Because of this, I can't use anything but a large platform peddle.

I have numerous braces they issued me (VA), but for most hiking and biking any distances, I use a Cho-Pat Dual Action Knee Strap

( they now come in colors, so my next one will match my blue bike when I wear shorts! )

Gives me the best support and freedom for these activities.

Physical therapist was very helpful on how to build up the knee area.
