Clinical results of anterior cruciate ligament reconstruction with ligament remnant tissue preservation: A systematic review

Abstract

Purpose: To clarify the effects of ACL remnant tissue preservation on the clinical outcome of ACL reconstruction. Methods: This is a systematic review. Results: The majority of the reviewed articles suggested that remnant preservation significantly improved knee stability after ACL reconstruction, although there was some controversy. In addition, it was suggested that the degree of initial graft coverage significantly affected postoperative knee stability. Remnant preservation did not increase the occurrence rate of cyclops lesion. Conclusion: Sufficient coverage of the graft with remnant tissue improves postoperative knee stability without any detrimental effects on the subjective and functional results.
