Endoprosthetic reconstruction of the proximal tibia continues to pose many challenges. A retrospective analysis of 44 consecutive patients who underwent cemented proximal tibial replacement were included to investigate if patient age, surgical stage, type of implant, stem diameter, or resection length could be associated with implant failure. Fifteen patients (34%) Suffered prosthetic failure, 7 due to infection. Prosthetic-related complications occurred in 13 patients (30%). Custom design prosthesis and longer length of resection were significantly associated with prosthesis survival in a Cox regression analysis (P = .001, hazard ratio = 8.747 and P = .044, hazard ratio = 1.217, respectively). Cemented proximal tibial replacement offers a functional knee, but reducing risk of complications still remains challenging. Prosthetic design and length of resection affect overall cemented endoprosthesis survival.
