Early and late infection as well as loosening and mechanical failure are among the postoperative complications most often reported following reconstruction with a tumour prosthesis in patients with a sarcoma around the knee. Scarce instances of periprosthetic fractures have been reported. The literature includes the description of two patients with such a complication, however no treatment recommendation was detailed in those articles. We recorded in our experience two patients with a traumatic fracture following a massive prosthetic bone and joint replacement after major resection for a bone sarcoma. The surgical treatment was open reduction and internal fixation using a cable and plate system, allowing preservation of the prosthesis and providing stable fracture fixation and excellent fracture healing.
