Does Allograft Augmentation of Small-Diameter Hamstring Autograft ACL Grafts Reduce the Incidence of Graft Retear?

Abstract

Adolescents undergoing an ACL reconstruction frequently have small hamstring tendon autograft size. The augmentation of these small grafts with allograft does not reduce graft failure rates and may in fact lead to higher retear rates, with earlier graft failure.
