Hi AMT. I am in my 20s with left knee post traumatic OA plus ligament damage. I used an ossur unloader brace for about 6 months. I have a job where I am on my feet a lot. Sometimes the brace felt irritating to wear, but overall it allowed me to feel more confidant on my feet and manage longer hours. It provided pain relief for me, but it is intended for medial compartment OA, so if you have OA in your lateral compartment I think it might not be a good option for you. I got mine through my own research on the internet and visiting an orthotics centre where they measured me up and ordered one in.
