# Development of an Original Three-Dimensional Computed Tomography Scan Method and Imaging Process for Surgical Support of the Anterior Cruciate Ligament

## TL;DR

This paper introduces a new 3D CT scan method to improve surgical planning for ACL reconstruction, reducing the risk of revision surgery.

## Contribution

The paper presents an original CT scan method and 3D imaging process specifically designed for anterior cruciate ligament surgical support.

## Key findings

- The new 3D CT scan method provides essential preoperative information for ACL reconstruction.
- The method accounts for changes in the foramen magnum angle related to femoral muscle mass.
- The proposed imaging process aims to reduce the risk of revision surgeries.

## Abstract

Three-dimensional computed tomography (3D CT) scan images are useful as they can provide information essential for surgical support, particularly in orthopedic surgery. In the case of anterior cruciate ligament (ACL) reconstruction, a 3D CT scan is important in preoperative simulation. Furthermore, it is associated with a reduced risk of revision surgery because the angle of the foramen magnum changes with the femoral muscle mass. However, the CT scan system geometry has several limitations. For example, the patient’s posture is limited during the procedure. Herein, we report an original CT scan method and 3D imaging process for surgical support of the ACL.
