Abstract
The main goal in anterior cruciate ligament reconstruction (ACLR) should be to restore normal knee biomechanics so the chances of failure decrease. The persistence of knee instability after ACLR goes from 0.7% to 20%. Several factors have been identified and studied, but there are some selected cases in which it seems that without adding lateral extra-articular tenodesis (LET) it is not possible to control rotational instability. Data exist supporting that LET could reduce pivot shift (PS), without losing flexion/extension range of motion nor adding risk of osteoarthritis. Recently, LET has been used in addition to ACLR to add restriction to internal tibial rotation forces, and different authors have shown their techniques to achieve this task. Also, biomechanical studies have compared different techniques for LET procedures. This article aims to describe our technique performing a modified Macintosh LET as an addition to ACLR in selected patients who require extra internal tibial rotation control. This is a reproducible, easy to learn, and inexpensive procedure in terms that only a high resistance suture is needed and not any other implant, such as a stapler, anchors, or screws, reducing the risk of tunnel coalition.
