Nobody can yet answer a fundamental question for sports hernia surgery:
After one gets sports hernia surgery and sutures and then recovers, and then begins participating with vigor again in one's sport of choice, what is to prevent one from getting another sports hernia injury?
In fact I've posted a couple of examples of news star athletes doing just this.
Yet no one can answer that question.
Why is this question unique to sports hernia surgery?
I do not know the stars you speak of, but not every surgery is going to be successful. Who were the doctors that operated on these stars? What was their experience? What were there methods?
My $.02 - if you've recovered as you suggest, then I'd guess it will take a long time to develop it again - this is not an injury that happens overnight. Just like a regular hernia does not happen by lifting something heavy. It was coming all along, developing for years. If these sports stars got the sports hernia again I would guess they never really recovered or weren't fixed properly to begin with.
