Limb salvage procedure for neoplasms about the knee by spherocentric total knee arthroplasty and autogenous autoclaved bone grafting

Spherocentric total joint arthroplasty was performed for treatment of neoplasm in 15 patients. The average follow-up period was 30 months. In nine of the patients concomitant autoclaved autologous bone implants were also prepared from the resected specimens. The results were satisfactory in ten patients and unsatisfactory in five. One patient had an infection that required amputation. One patient with osteosarcoma had a recurrence at 20 months and was treated by amputation. Poor results were caused by stem failure in two patients and by component loosening in one patient. Total joint arthroplasty combined with autoclaved bone implantation is a useful limb salvage procedure for resected neoplasms about the knee.
