Nothcplasty in Acute Anterior Cruciate Ligament Reconstruction.

Nota Técnica y Revisión Bibliográfica

Abstract

ACL tears are the most frequent ligament injuries of the knee. There are factors that predispose and increase the risk of suffering this type of injury. They are divided into extrinsic and intrinsic. The latter are related to the patient's anatomy and can predict a risk of ligament injury. These include height, weight, tibial slope, limb axis, posterior anterior laxity, ACL size, Q angle, and dimensions and shapes of the femoral intercondylar space. A narrow space increases the risk of contact of the anterior cruciate ligament against the anterior wall and the roof of the intercondylar stool increases the rate of rupture.

Notchplasty is not usually performed, since the anatomical position of the reconstruction reproduces the anatomy of the anterior cruciate ligament, which does not produce friction with the intercondylar walls. However, in patients in whom the narrow intercondylar space is detected, or in the "A Shape", according to Fu’s classification, a wide notchplasty is performed to look for the femoral isometric point, avoiding friction of the injection, the extension deficit and improve the functional result.

The objective is to identified "A Shape" notch, and to describe a notchplasty technique in acute ACL reconstruction.
