Totally depends on 3 things-what exactly was repaired, whether it was done in open surgery or laporascopically, and of course complications. He is young which is a big plus. Most hip surgery statistics are based on much older patients so they may not be of any predictive value in this case. There is a massive difference between doing a little muscle tear repair and trying to repair a labrum or some cartillage or shaving some bone. Being able to do any procedure through a small laporascopic incision usually prolongs the time it takes to do the surgery but shortens the healing considerably. Complications? Who knows-there are just so many things to have to watch for and some you just cannot prepare for in any way. I would suspect if this was the most minor of corrections that we are looking at 3 months minimum before any serious skating can begin. Worst case scenario is perhaps as long as 18 months (egad! Yes even in a healthy 20+ year old it can take that long). And of course we are not talking about just recovering to be able to walk and support himself-we are looking for the recovery time to be able to skate with power and speed and absorb contact. One saving grace is that hip surgery recovery is often quicker than serious knee surgery recovery as a ball and socket type joint is far more stable and able to support weight than a hinge type joint. My best guess(without knowing many details) is he could be skating by October-but if not, then it could be a season long recovery issue.
In the past this was done before the end of the school year.
