[Prosthetic arthroplasty in the region of the knee for musculoskeletal tumours].
The authors evaluated a group of 23 patients (13 women and 10 men) with resection of the distal end of the femur or proximal part of the tibia for musculoskeletal tumours in the knee joint region. Resected bone was replaced by individually made tumorous total endoprostheses. Most frequently the authors operated on account of osteosarcoma (13 cases) and chondrosarcoma (5 cases). The proximal tibia was replaced in 11 patients, the distal femur in 12 patients. Endoprosthesis of 5 types and from 4 firms were used. Johnson and Johnson implants and Poldi type were most frequent. Hinge endoprostheses of all types exhibited a lower movement range in replacements of the distal part of the femur as compared with a higher movement range in replacements of the proximal part of the tibia. Subjectively best results for patients were achieved wih composite endoprostheses with a highly congruent surface.
