Mohan R, et al. – This study assessed overall objective graft failure rate, failure rate by graft type (allograft vs autograft reconstruction), instrumented laxity, and patient outcome scores after revision anterior cruciate ligament (ACL) reconstruction. The findings demonstrated similar failure rates for revision ACL reconstruction and autograft or allograft reconstruction. Although overall outcome scores for revision reconstruction have improved but appeared modest when compared with primary ACL reconstruction surgery.
