Delaloye JR, Hartog C, Blatter S, et al. - This study was intended to ascertain the stabilizing role of anterolateral ligament reconstruction (ALLR) and modified Lemaire lateral extra-articular tenodesis (LET) performed in combination with anterior cruciate ligament reconstruction (ACLR) and to determine whether either procedure was superior to the other. Researchers tested six nonpaired, human, fresh-frozen cadaveric knees with a 6-df robotic system. They further reported internal rotation and anterior translation of the knee from 0° to 90° of flexion after application of a 5-Nm internal rotation torque and a 134-N anterior load, respectively. They conducted a full kinematic evaluation in each of the following conditions: intact knee, after sectioning of the anterior cruciate ligament (ACL), after sectioning of the ACL and anterolateral ligament, after isolated ACLR, and after combined ACLR and Lemaire LET and combined ACLR and ALLR. The data reveal that combined ACLR and anterolateral reconstruction restored the native knee stability in anterior translation and internal rotation contrary to isolated ACLR in knees with ACL and anterolateral deficiency. They found similar extra-articular reconstruction-ALLR and modified Lemaire LET- in terms of restoring knee kinematics, and neither overconstrained the knee.
