The width of epiphysis was measured by using whole standing leg radiographs with a 1-mm precision scale. The distance between the intersection of the line that was placed parallel to the joint surface and passed through the medial and lateral cortex at the level of intercondylar fossa in the distal femur before surgery and at the latest examination (a 10-year-old boy with osteosarcoma of the right distal femur, 55 months after surgery) (a). The width of the epiphysis of the proximal tibia was measured by a line that was perpendicular to the tibial anatomical axis and passes through the medial edge of the medial condyle. The distance between the ends of the medial and the cross point to the mechanical axis was measured on the proximal tibia before surgery and at the latest examination (an 11-year-old girl with osteosarcoma of the right proximal tibia, 42 months after surgery) (b)
