title: Two-stage knee arthrodesis using a cemented modular tumour replacement system for recalcitrant septic proximal tibial non-union: a case report.
abstract: Knee arthrodesis is an alternative to amputation for treating recalcitrant septic non-union of the proximal tibia with bone loss, soft-tissue compromise, and knee-joint involvement. Nonetheless, arthrodesis is difficult to achieve if bone loss is massive, and the septic environment can result in failed bone fusion. We report on a 77-year-old man with massive bone loss secondary to recalcitrant septic non-union who underwent radical bone resection, followed by knee arthrodesis using a cemented modular intercalary megaprosthesis in conjunction with a microvascularised flap in 2 stages.
