Lateral tibial bone mineral density around the level of the proximal tibiofibular joint

Purpose During open-wedge high tibial osteotomy, fracture occurring in the insufficient osteotomy before distraction of the osteotomy gap is an important complication. The objective of this study was to evaluate bone mineral density (BMD) around the proximal tibiofibular joint (PTFJ) and the osteotomy hinge. The hypotheses of this study were (1) BMD would be higher in the level of PTFJ, compared with that of above—or below—the level of PTFJ, (2) BMD of the posterolateral side of the hinge would be higher than that of the anterior or lateral side.
