Universal coupled isometric guide for ligament reconstruction of the knee ("G.U.I.A.").

Abstract

The author presents a new drill guide for reconstruction of the knee ligament called "Guia Universal Isométrico Acoplado--G.U.I.A." (Universal Coupled Isometric Guide). The guides uses the posterior region of the intercondylar notch to obtain the femoral tunnel for the anterior cruciate ligament (ACL). Based on biomechanics, literature and cadaver knee studies, the guide has proved to be practical, to facilitate the preparation of isometric tunnels and to avoid iatrogenic injuries.
