The objective of this study was to compare a nonaugmented autogenous anterior cruciate ligament (ACL) graft with an autogenous graft augmented with Leeds‐Keio polyester mesh (L‐K mesh) when the augmentation was fixed to bone at both ends or fixed to bone at one end. Twenty‐six rabbits were divided into 3 groups (nonaugmented, augmented with one‐end fixation and augmented with two‐end fixation), and were evaluated 12 weeks postoperatively. The gross findings demonstrated adhesion of the proliferated infrapatellar fat pad to the reconstructed ACL in the autogenous group, but not in the augmentation groups. The microangiographic study revealed poor revascularization in the augmentation groups. Histologically, in the L‐K two‐end fixation group, the biological segment of the reconstructed ACL remained necrotic. The biomechanical study showed that the augmentation groups were significantly stiffer and stronger than the nonaugmented graft
