There are a couple of questions that need to be answered first. Is there any mobility at all left at the ankle? Why did the client need this surgery? Has there been physical therapy? What were the results of any therapy? Is there pain in the ankle? Are other joints being affected and if so, how?
I know this question was asked a long time ago. If you are still getting emails on this question, get back to us on how things are going. And let us know about your experience with this and what worked/didn’t work, etc.
