Primary ACL Reconstruction in Patient Over 40 Years: Allograft Versus Autograft

Primary ACL Reconstruction in Patient Over 40 Years: Allograft Versus Autograft, a Prospective Matched Paired Comparison

The aim of this study is to investigate the differences in graft failure between patients that underwent ACL reconstruction using allograft tendons and patients that underwent ACL reconstruction using autograft tendons in patients older than 40 y.o. and after at least 2 years of follow-up.
