I was diagnosed with moderate arthritis of the subtallular ankle joint. Dr. says no research has been done indicating help for arthritis in this joint. He said that this joint is very complicated. The only recourse is to adjust my orthotics. He does not believe that any injections will help including cortizone, PRP, or stem cell. He said way down the road, a fusion might be considered. I will never have a fusion or any surgery done on my ankles or feet. I do not want to wait for my condition to get that bad to have anything done. Is there anyone out there with this condition? Is there any research or trials to test treatment for this particular joint? Is there anyone who can advise me on what to do about arthritis in the ankle?
