Summary

In anterior cruciate ligament (ACL) reconstruction, navigation and robotic assistance now provide the possibility of precise positioning of the tunnels.

The challenge is therefore to carry out isometric preoperative planning which can be carried out with robotic or navigation assistance.

In the classic reconstruction technique this isometry is assumed by positioning the tunnels on the center of the native ACL footprints. However, studies cast doubt on this hypothesis.

In this work, the investigators will study the isometry of the center of the native footprints on a dynamic 4D scanner in order to obtain the variation in the distance between the centers of the native footprints during a knee flexion cycle.

This study is part of a larger project. the objective is, if the absence of isometry of the center of the native impressions is confirmed, to develop software assistance which will help the surgeon plan preoperatively an isometric reconstruction. The hypothesis is that the techniques based on the center of the native footprints does not allow isometric reconstruction.
