Fig. 1

A Three-dimensional reconstruction femoral model generated using Mimics 21.0 and B smoothed using Geomagic Wrap. C The Wagner cone stem is implanted into the femoral medullary cavity with a 20° anteversion angle. D The implant axis of the femur is established after the Wagner cone stem is implanted. E Seventeen selected levels from 0 to 8 cm below the LT at 0.5 cm intervals. F The center point circle method for the 17 selected levels. G The central points of the medullary cavity are overlapped in pairs according to the osteotomy length. A pruning tool is used to obtain the corresponding overlap area of cortical bone. The black arrow indicates the implant axis of the femur
