Figs. 2-A and 2-B Measurement of the tibial tuberosity lateralization. Fig. 2-A The total width of the proximal tibial condyle, which is parallel to the tibial posterior condylar line (tPCL), indicated by the dashed line, is defined as T. Fig. 2-B The distance between the medial border of the proximal tibial condyle and the tip of the tibial tubercle, which is parallel to the tPCL, is defined as t. Tibial tuberosity lateralization is calculated as t ÷ T.
