Editorial Commentary: Tibial Slope Should Be Naturally Maintained by Proper Posterior Cortical Osteotomy and Gap Distraction in Open-Wedge High Tibial Osteotomy

The tibial slope usually increases after open-wedge high tibial osteotomy (OWHTO) because of several factors. The anteromedial cortex of the proximal tibia is angulated 45° relative to the posterior cortex, whereas the lateral cortex is nearly perpendicular. Therefore, an OWHTO with equal anterior and posterior gaps will increase the tibial slope. In addition, an anteromedial approach to the proximal tibia because of concern about neurovascular...
