One major use for high tibial osteotomy (HTO) aims at improving alignment in the symptomatic, varus malaligned, medial compartment osteoartritic knee. The importance of achieving correct alignment is obvious upon considering the increased potential for significant complications with over- or under-correction in any plane. This systematic review searched the MEDLINE and EMBASE databases to compare the short-term clinical and radiological outcomes between patients undergoing either conventional or navigated HTO. We retrieved 52 articles which ultimately resulted in nine eligible studies for inclusion. Though heterogeneity prevented statistical analysis, only one study failed to suggest superiority of navigation over conventional techniques. We conclude that navigated high tibial osteotomy improves accuracy over conventional techniques, though the current best evidence presented herein must be advanced by higher quality studies.
