Skeletal reconstruction after tumor resection of the distal femur

After tumor resection of the distal femur, limb salvage with preservation of joint function may be achieved using endoprostheses or osteoarticular allografts or a combination of the two (composite allografts). The choice among these reconstructive solutions must be made considering the functional results achievable and the risk of failure of the implant. The present literature review suggested that prosthetic replacement of the distal femur is more reliable than osteoarticular allograft at long-term follow-up.
