[Implantation of a Modular Distal Femoral Replacement with Compressive Osseointegration as a Salvage Procedure in a Complex Femoral Posttraumatic Setting].

Background: Large bone defects and losses play a crucial role in both tumour surgery and in complex primary and revision total knee replacement. The established options of cemented or uncemented long intramedullary stems are limited by large bone defects and are at risk from relatively high exposure to aseptic loosening. There is no general valid agreement on implant fixation of the distal femur.
