Takeuchi R, et al. - This study entailed a comparison of mechanical fixation strengths of anteromedial and medial plate positions in osteotomy. Furthermore, researchers intended to shed light on the impacts of bone substitute placement into the osteotomy site. Findings demonstrated biomechanical superiority of a medial plate position over an anteromedial position if bone substitute was not used. Also, it was observed that bone substitute distributed the stress concentration around the osteotomy gap and prevented an increase in tibial posterior slope (TPS) angle regardless of the plate position.
