Fig. 2From: Analysis of radiographic factors affecting the significant differences in knee alignment between hip-to-talus and hip-to-calcaneus radiographs after opening-wedge high tibial osteotomyWeight-bearing line (WBL) ratio on the two lower extremity radiographs. The WBL line was drawn from the center of the femoral head to the center of the superior surface of the talus (A hip-to-talus radiograph) or the lowest point of the calcaneus (B hip-to-calcaneus radiograph). The WBL ratio was determined as the percentage by dividing the length from the medial portion of the proximal tibia plateau to the point where WBL crossed the proximal tibia plateau by the total length of the proximal tibia plateauBack to article page
