Abstract in different language: A total knee arthroplasty (TKA) is in rare cases followed by an extra-articular fracture of distal femur. One type of fracture is a simple extra-articular fracture (A1 according to Schewring and Meggitt). It can be stabilized only by surgical treatment. Several implant types are used by orthopedic surgeons for its management. In this study we compare a response to axial load and torque for Distal Femoral Nail (DFN) and Locking Compression Plate (LCP). The model of bone with fracture, TKA and DFN is the same one as in the previous study. Both compact and spongy bone are modelled by 3D elements. The gap of partially healed fracture with a callus is 2 mm wide. LCP geometry is based on a laser scan. The finite element models with the placement of DFN and LCP are shown in Fig. 1. The material parameters of bone were obtained from available literature, the callus which forms several weeks after the fracture has material properties of a cartilage. The screws, the spiral blade, DFN and LCP are made of titanium alloy.
