[The effect of the posterolateral bundle in the anterior cruciate ligament reconstruction].
The use of new technology in 3D laxity analysis in torn anterior cruciate ligament (ACL) knee has recently improve the ability to assess the effect of reconstruction on laxity control. The aim of this study was to compare, in anatomic ACL reconstruction, the effect of each bundle, posterolateral (PL) and anteromedial (AM) on the residual laxity intraoperatively. We used an optoelectronic navigation system to measure the translation and the rotation during anterior drawer test, Lachman test and pivot shift test. Twenty-two patients were assessed with two protocols, group I with PL bundle reconstruction following the AM bundle reconstruction and group II with a reverse program. Addition of PL bundle has significantly improved the translation and rotation laxity control during the Lachman and pivot shift test, when the AM bundle was more important in the translation control during the anterior drawer test. Anatomic double bundle reconstruction improves the control of laxity intraoperatively.
