Best of luck with your surgery, evanlo. Make sure your doctor knows how active you are and that you intend on continuing with kiting. Maybe that will impact the actual method or implant he uses. If you haven't done so, I'd get multiple opinions on the surgery and ask each doctor how it is done. I had a rotator cuff repaired last year, even though it was standard surgery, 3 doctors had 3 slightly different methods. Each impacted rehab time and how early I could start PT. It was very valuable to talk to all 3 and make my own decision. (if you haven't done that, do so, even if you already have a surgery date. you can cancel that if you find a surgeon you like better)
Having said that, keep in mind you are not likely to find a surgeon who understands kiteboarding. As much as I tried to explain the mechanics to my doctor, they don't have the time to really pay attention. He kept calling it "windsurfing" and when I reminded him it was kitesurfing he assumed that I was hanging on to the kite for dear life and was much more conservative in his advice. i.e. he didn't really undestand how harnesses work and that the sport does not require huge upper body strength. Granted, there is always a risk of doing an unintentional superman, but you'll just choose your first sessions carefully. My first session after surgery was a 12M strapless day with with moderate wind. Very forgiving.
You'll do fine. Make sure they know you will kite and you are not a crazy thrill seeker. (i.e. lie
) And do all your rehab PT exercises with a vengeance.
