Distal femoral replacement is an orthopaedic procedure which is most commonly associated with the sarcoma population. The distal portion of the femur (up to two thirds) is excised and replaced by a endoprosthesis incorporating a hinged total knee replacement.


The most common indication is a bone tumour located in the distal femur.
