Just supporting physiobob's statement, if it is asymptomatic, surgery is not indicated. You may just as likely have symptoms post surgery due to the nature of surgery itself, leaving you in a worse position!

I would assume an ortho specialist will likely reject surgery in this case anyway. I have seen multiple asymptomatic peroneal subluxations following repeat ankle sprains in basketball players and rugby players who don't seem to be too affected by it in the long term.
