Image-Free Navigation in ACL Replacement with the OrthoPilot System

Abstract

In many areas of surgery, ever smaller approaches are being sought to reduce soft tissue traumatisation in minimally invasive operating techniques. This is associated with the danger that the surgeon will lose an overview of the topography of the structures as a whole. Computer-assisted navigation promises to remedy this. Computer-assisted surgery began in the 1990s with intracranial neurosurgical operations and the implantation of pedicle screws in spinal surgery, using CT and MRI imaging. Today however, there are other solutions which do not require pre- and intraoperative X-rays. One of these solutions is offered by the OrthoPilot navigation system (⊡Fig. 54-1).
