Megaprostheses in the management of trauma of the knee

ObjectiveReview the outcome of patients with complex fractures around the knee treated with megaprosthesis.MethodRetrospective observational study of 10 patients was undertaken.ResultsSix patients were treated with a distal femoral endoprosthesis (DEFPR) and four with an augmented rotating hinge knee replacement (RHK). The mean post-operative Toronto Extremity Salvage Score (TESS) was 62.5 for the whole cohort (RHK group 79.3, compared with 49.2 in the DFEPR group (p = 0.038), peri-prosthetic fracture group was 46.3, compared with 75.6 in native knee fracture group (p = 0.04)).ConclusionA megaprosthesis is a viable option in complex fractures around the knee.
