The hypothesis is the arthroscopic centralization will decrease the laxity and rotation of the ACL\u2010reconstructed knee.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Twelve fresh\u2010frozen porcine knees were tested using a robotic testing system under the following loading conditions: (a) an 89.0\u00a0N anterior tibial load; (b) 4.0\u00a0N m internal and external rotational torques. Anatomic single\u2010bundle ACL reconstruction with a 7\u00a0mm\u2010diameter bovine extensor tendon graft was performed. A massive, middle segment, lateral meniscus defect was created via arthroscopy, and arthroscopic centralization was performed with a 1.4\u00a0mm anchor with a #2 suture. The LM states with ACL reconstruction evaluated were: intact, massive middle segment defect and with the lateral meniscus centralization procedure.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The rotation of the ACL reconstructed knee with the lateral meniscus defect was significantly higher than with the centralized lateral meniscus under an external rotational torque at 30\u00b0 of knee flexion, and under an internal rotational torque at 30\u00b0 and 45\u00b0 of knee flexion. There were no systematic and consistent effects of LM centralization under anterior tibial translation.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>In this porcine model, the capsular support of middle segment of the lateral meniscus using arthroscopic centralization improved the residual rotational laxity of the ACL\u2010reconstructed knee accompanied with lateral meniscus dysfunction due to massive meniscus defect. This study quantifies the benefit to knee kinematics of arthroscopic centralization by restoring the lateral meniscal
