There is very little in the way of documented answers in the medical literature, so I don't think I can provide much insight. However, to the "big" question "Do I have to quit my sport?" I don't think so. But what might give you the best chance for that outcome? For one, you might consider finding the very best physician for your specific problem.
Yes, you have a board-certified sports medicine doctor, and that is great. He (or she) may be excellent. But here is what I would do, if in your position. I'd find the very best doctor (in the world) for this problem, and I'd go see him/her. I'm talking about someone who does many of these, preferably in the 100's every year, and is not only deeply interested in the problem, but is highly technically skilled for your particular issue.
To give you an example, a former partner of mine and I love to ski. He lives in Colorado, and I live the NE US. When his knee started going bad, it soon became apparent he needed a knee replacement. Now what. Well we researched and found a surgeon with incredible results, and he went to see him and his staff. The team had an incredible program that promised (not kidding) he would be walking up steps in an hour-and-a-half after total knee replacement. I did not believe it. Well, he travelled the 1500 miles and had the surgery done there. And in an hour-and-a-half he was walking up steps! My mouth dropped open. That was in November, two years ago, and by the end of December, he was skiing...and skiing well, just like he did in his teen years.
Don't know if you got the "gist" of what I am saying to try to help, but your questions to anyone who is to operate on you should include 1) how many of these (including repeats) have you done? 2) how many do you do a year? 3) Can you give me some statistics on your results? 3) what can I truthfully expect as an outcome.
Hope this helps, Jamie. My intent was to help provide you with some direction Tthough I do not have more specific answers for you, someone does. Wanted to help as best I could, and can't spend more time, though I found a doctor to whom I would go, if I had your problem: NR Howells, Nuffield Orthopaedic Center, Oxford, England. Look him up. Problems of your specific type are his lifelong interest. Yes, I would call, write, then be prepared to get on a plane, and go.
