Have grade 3 cartilage damage in my right knee and was supposed to get maci surgery but ran into a insurance problem, would a unloader brace help until i can get maci surgery?

Yes: This brace will not replace the need for surgery, but,properly fit, it will,stop,pain, and allow better walking pattern. You should be checked to make certain that rotation is not a problem as well. Ask you doc to refer you to a competent orthotist to correctly measure for this custom brace, and teach you how to place it correctly for best results. Weight should be maintained =/- 15 lbs, once fit.
