My operation results were very positive, although there was still some minor impingement in the joint. I never returned to full range of motion unfortunately.
There were no after-effects from surgery and no pain in the joint at all. I was able to return to playing football, although I have never quite gained the same amount of confidence. Doing things (such as sport) in moderation is key. I would recommend an MRI scan and a very detailed diagnosis. It is possible to recover from this type of problem, and my results from surgery were very positive.
I suffered another minor sprain a few months later on the same ankle, and have not returned to sport since. I will attempt do some further running in the short term (after rest). I will also look at perhaps another scan next year to see if there has been further degradation.
Good luck!! Do you feel that it is bone or tissue impingement?
