Tumor endoprostheses are increasingly employed in symptomatic metastases of the long bones, and have enabled limb-salvage surgeries in original bone and soft tissue sarcomas. The themes of the chosen studies substantially matched the primary research issues presented in a consensus conference, with the survival result of orthopaedic implants being the most regularly voiced research question. Research on endoprosthetic tumour repair should also look at possible preventive approaches, since numerous studies have reported on the possibility of deep infections. In this brief review, we want to critically examine the current research on reconstructive surgery with megaprostheses. This literature review aimed to synthesise the most recent findings on cancer endoprostheses by analysing publications published over the last three years. In this article, we want to take a critical look at the existing literature on reconstructive surgery with megaprostheses. We detail the development of megasprosthetic implants, whether they are appropriate for usage, and what happens before and after surgery so that the general orthopaedic surgeon may become acquainted with a procedure often reserved for specialty hospitals.
