Well, for anyone who's interested, I did a lot more research, spoke to a number of people who have gone through ACL reconstruction, and double checked with my surgeon. Hamstring option is best for me; using the patella tendon leads to chronic knee pain. And as long as I do PT, there's an excellent chance I'll have 100% use of the knee -- which means back to competitive sparring. I'm a happy camper -- or I will be, once my surgery is done in early January. I'm looking forward to being active again; this sitting-on-my-duff thing got old within 48 hours, and I am so over being exhausted just running (hah - see what I did there?) errands. Bring on the surgery and the 8+ months of PT!
