The diameter of single bundle, hamstring autograft does not significantly influence revision rate or clinical outcomes after anterior cruciate ligament reconstruction by Wernicke et al is quite important because it correctly debunks the entire topic of evaluating Hamstring (HS) diameter for Hamstring ACLR. After over 30 years of exclusive use of HS autograft I can conclusively state that our studies have demonstrated that the HS is ALWAYS big enough, when quadrupled, to successfully reconstruct the ACL.
