Concomitant Lateral Meniscus Injury Aggravates Rotational Laxity of the Anterior Cruciate Ligament Injured Knees

摘要

Objectives:Residual rotational laxity in the anterior cruciate ligament (ACL) reconstructed knees is a remaining problem after the ACL reconstruction. Improper detection and treatment of the secondary restraint for the knee rotational laxity after the ACL were considered as the major reason for the problem. Although anterolateral ligamentous structure of the knee has increasingly been focused on, meniscus injury is frequently accompanied with the ACL injury and assumed to have significant impact on the rotational laxity based on previous studies. The purpose of this study was to determine the effect of the meniscus tear on the rotational laxity in the ACL-deficient knees.
