Hi Seanmc,
Best advice I can give you is get to a nearby Chartered Physiotherapist that has dealt with high level sports teams - They will have seen the outcomes of a few of these procedures and give you an indication of where you're at. Unfortunately once you have surgery that's not always the problem just "fixed" and unless you've rehabbed everything from ROM, strength, balance not just in the ankle but higher up the chain - problems may persist.
You can always go back to the Surgeon and see what they say - Generally i'd try make sure you have rehabbed everything to as high a level as possible first - That way they know you've covered everything else.
It's not a quick fix unfortunatley - Good Luck
