I am 35 years old, weigh 185lbs and have a limited medical history. What I am wanting to know is: Which tendon would be the best to use in the case of ACL reconstruction? I have been told both the patella and the hamstring by two different doctors. I am extremly active and compete in multiple sports, including but not limited to, MMA, snowboarding and trainging with the Navy Seals. Both claim that the tendon that they mentioned was the best for what I do so now I am a little put off as to which tendon would actually be the correct one. The most recent doctor (The doctor I currently have my surgery scheduled through) is telling me the patella as it will stretch the least over time. Needless to say, I am at a loss. Is one proven to be better than the other? Thank you for you time.
