As the number of total knee arthroplasties performed continues to increase, complications such as postoperative periprosthetic fractures are becoming increasingly more common. Femoral periprosthetic fractures are the most common type of fractures around a total knee arthroplasty, whereas tibial and patellar periprosthetic fractures are infrequent. Treatment principles depend on the bone the fracture is located, the status of the implant fixation, bone stock, and the type of implants available. The Vancouver classification allows for a standardized system to describe and manage these injuries, incorporating these factors. A systematic approach is vital in obtaining the best possible outcomes because complications and mortality rates mimic those of hip fractures.
随着全膝关节置换术数量的不断增加，术后假体周围骨折等并发症也越来越常见。股骨假体周围骨折是全膝关节置换术后最常见的骨折类型，而胫骨和髌骨假体周围骨折则较为少见。治疗原则取决于骨折部位的骨骼、植入物固定的状态、骨质和可用的植入物类型。温哥华分类法提供了一种标准化的系统来描述和管理这些损伤，将这些因素纳入其中。系统的方法对于获得尽可能好的结果至关重要，因为并发症和死亡率类似于髋部骨折。
