The introduction of multidisciplinary approach with chemo and radiotherapy, the advances in surgical and the improvements of diagnostic techniques allowed limb salvage surgery in most cases of bone sarcomas instead of amputation. Modular megaprostheses are the most common method of reconstruction after segmental resection of the long bones in the extremities for their availability, immediate fixation, early weight bearing, good function. Despite the advances in materials and implant designs, these systems have an high incidence of complications. Aim of this study was to report the experience on mega-prostheses implanted around the knee in tumor and revision surgery to analyze: the most frequent used current systems, the problems of stems fixation, extensor mechanism reconstructions in proximal tibia resections and the preservation of growth of the lower extremity in children.
多学科化疗和放疗方法的引入、外科手术的进展以及诊断技术的改进，使得在大多数骨肉瘤病例中可以进行保肢手术而非截肢。模块化大假体因其可用性、即刻固定、早期负重和良好功能，是四肢长骨节段切除术后最常用的重建方法。尽管材料和植入物设计有所进步，但这些系统并发症发生率很高。本研究的目的是报告在肿瘤和翻修手术中植入膝关节周围大假体的经验，以分析：当前最常用的系统、柄部固定问题、胫骨近端切除术中伸肌机制重建以及儿童下肢生长的保留情况。
