title: Revision of distal femoral endoprosthetic arthroplasty with impacted morsellized allograft.
abstract: We report the use of contained impacted morsellized allograft to revise an aseptically loose, massive distal femoral cemented endoprosthetic replacement in a 27-year-old caucasian woman. The prosthesis was inserted 4 years earlier, following neoadjuvant chemotherapy and resection of a distal femoral high grade osteosarcoma. Impaction grafting was used to restore bone stock and maintain femoral length. The patient remains disease free with excellent function, at one year after revision with no evidence of loosening and maintenance of bone stock. We believe it is the first time this technique has been used in revision of a distal femoral endoprosthetic replacement.
