Purpose: The primary aim of this study was to evaluate the 3D morphology of the proximal tibia around the osteotomy plane in open-wedge high tibial osteotomy (OWHTO), focusing on the posterolateral (PL) and posteromedial (PM) tibial condyles, and to clarify the changes in morphological parameters due to differences in patient characteristics and hinge position. The secondary aim was to examine whether morphological features were associated with insufficient osteotomy, which increases the risk of lateral hinge fracture (LHF).
Methods: The PL and PM anteroposterior distance, asymmetry ratio, and discrepancy between PL and PM distances along the tibial osteotomy plane were measured. Read More
