Navigation Guided Corrective Osteotomy (Based on Surgical Technique)

Abstract

The success of corrective osteotomies around the knee largely depends on the accuracy of the intended correction. Traditional techniques to assess intraoperative alignment are rather subjective and the use of navigation is considered more accurate. This has been proven in multiple studies and is seen as the main advantage of this technique. Other benefits of navigation guided osteotomies are more accurate assessment of sagittal alignment (tibial slope), dynamic evaluation of alignment, and less radiation exposure. However, despite the increased accuracy of navigation guided osteotomies, the evidence of improved clinical outcomes is still lacking. Specific complications of navigation are uncommon and are related to the reference array pins. The main limitations of this method are the additional steps, and thus longer operative time, the significant learning curve, and the extra costs. The last aspect of this chapter comprises the surgical technique and focusses on the preoperative assessment, the surgical setup, the registration of the landmarks, the osteotomy, and the rehabilitation.
