Abstract

Osteosarcoma is the commonest primary malignant bone tumour which has a bimodal age distribution and presents mostly around the knee joint. With advances in chemotherapy, medical imaging, surgical techniques and implants, limb salvage surgery (LSS) has become a norm. However, prompt referral to specialist units and multidisciplinary (MDT) approach remains the key that has led to an increase in the survivorship of these patients over the last few decades. Reconstruction around the knee joint following resection of osteosarcoma remains a challenge due to multiple reasons and options including biological and non-biological techniques. In lower-lower-middle-income countries (LMIC), this challenge becomes further compounded because of financial limitations. We report 2 cases where a frugal method of reconstruction following resection around a knee joint was used for LSS and arthrodesis was achieved with intramedullary nails and bone cement (PMMA) and both patients were mobilized full weight bearing immediately after surgery.
