Re: oats surgery
There was a similar thread just the other day, called "oats ankle surgery." As I type this, it's on page 2 of the Foot Problems board, and it has lots of the info you're asking about.
I was treated by a podiatrist at the beginning of my injury, but once surgery was inevitable, I researched and switched to an OS/foot-ankle specialist. I would not want my surgical options to be dictated by the limitations of my surgeon's license.
