Look into Unloader braces.
I've got pretty severe OA in the medial area of my right knee, and the unloader was a real lifesaver before i got a Meniscus Transplant and OATs and has been a MAJOR lifesaver in my recovery from the surgery. I still wear it.
Ossur is the brand that I have. I also got a custom made CTI-Unloader, but i find the regular unloader does a better job.
Hope that helps
