First of all the authors limit the indications to resection arthrodesis in bone tumors located near the knee joint and present the main features of the procedure. These consist of the technical requirements for a radical operation, the type of osteosynthesis with special supports and the type of compensation for the defect. Based on the well known surgical techniques of Juvara, Merle d'Aubigné and J.Böhler, a precedure was presented which has been clinically tested for 6 years. In this procedure which is based on individual locations of tumors, a homologous bone canal helps to compensate the resection defect. The biological characteristic of the healing of this interponate was described. Finally, recommendations for postoperative aftercare were presented whereby the long support in orthopedic apparatus and the renewed spongiosa accumulation as a result of the removal of the metal were mentioned.
