Hi Molly,
I feel for you. I had the same thing and skiied for years. I used a Lennox-Hill brace that unloaded the medial side of the joint.They worked well for many years. I have had other braces that never fit or worked quite as well. I am a physical therapist and have a ton of patients with this problem. You can try bracing but remember that they can limit knee motion and increase torque at ther knee.This may or may not be good for your knee. Good luck!

Tim
