The purposes of this article are to review current concepts of knee replacement, including features of traditional and newer prosthetic designs, materials, and surgical techniques; illustrate normal and abnormal postoperative imaging findings; and to relate the complications to current understanding of how and why these failures occur.
Complications after knee replacement may be asymptomatic. For this reason, assessment with postoperative imaging is important. The foundation of radiologic interpretation of knee replacement is knowledge of the physiologic purpose, orthopedic trends, imaging findings, and complications.
本文旨在回顾膝关节置换的现有概念，包括传统和新型假体设计、材料和手术技术的特点；阐述正常和异常术后影像学表现；并将并发症与目前对这些失败发生的原因和方式的理解联系起来。
膝关节置换后的并发症可能无症状。因此，术后影像学评估很重要。膝关节置换的影像学解读基础是了解其生理目的、骨科趋势、影像学表现和并发症。
