I've heard of the procedure - but don't know anyone who has had it done. I have had 5 knee surgeries in about the past 15 years of so. The only advice I can give you is make sure she listens to her doctors and does the rehab as told. I thought if I pushed myself a little harder I would get full use of my knee back quicker (impatient youth thing) - didn't work out that way, lol. In my right knee I now have scar tissue interfering with the tendons & ligaments. When I had the surgery on my left knee I actually listened and that one healed very well and I haven't had any issues with it. I have had additional surgeries trying to fix the problems with the right knee, but still have a lot of problems. In order to fix it the way they should would be major and I'm not willing to do that unless I absolutely have to. These gymnasts tend to be the type to push themselves and fight through pain - try not to let her do that - she will be better off in the long run that way. Good luck to her and keep us filled in.
