Abstract The authors used computer navigation to perform osteotomies around the knee. The purpose of this article is to present the authors' surgical technique and to discuss double-level osteotomy of the femur and tibia to avoid altered joint line obliquity in genu varum deformity. The authors conducted two studies. The first study was a cohort study comparing navigated high tibial osteotomies and conventional high tibial osteotomies. The results showed a 96\% reproducibility in achieving a mechanical axis of 184 degrees +/- 2 degrees in the navigated group compared to a 71\% reproducibility in achieving a mechanical axis of 184 degrees +/- 2 degrees in the conventional osteotomy group (P < .0015). The second study was a prospective study on double-level osteotomy and showed that the preoperative goal of 182 degrees +/- 2 degrees has been achieved in 91\% of patients.
