Hi Keith, welcome to the site, you're in the right place. I think you'll find plenty of hockey players, just this month a goalie checked in to see whether he would be able to continue after the procedure; another goalie already back to playing answered him. I hope several will check in, but I do think it's possible in time. I don't play hockey but did (and still do) use a slide board for recuperation, so take that for what it's worth.
I know a lot of people have gone back to golf; I'm in the process of getting back to martial arts, along with others. You can check, we have many triathlon athletes, motorcycle and bicycle athletes, competitive horse riders, runners, sprinters, skiers, surfers, basketball, a long and illustrious list of sports that hippys return to.
The risk is there, but the odds are heavy for success (96% at last check), and Dr. Brooks has a great reputation. Everyone is nervous, but it is a real gamechanger and lets you get your life back. Check out the site, there's a list of questions to ask your surgeon here:
