Increased implant longevity, improved range of motion, and the use of total knee arthroplasty in younger and more active patients have placed greater demands on the patella component. Commonly observed complications of the patellofemoral joint are crepitation, subluxation, excessive wear, loosening, and persistent patient discomfort. These complications have been attributed to inadequate prosthetic design, fixation techniques, anatomic abnormalities, and surgical error. This paper reviews the most prevalent complications and discusses their causes and prevention.
植入物使用寿命的延长、活动范围的改善以及全膝关节置换术在更年轻、更活跃患者中的应用，对髌骨组件提出了更高的要求。髌股关节常见的并发症有摩擦音、半脱位、过度磨损、松动以及患者持续不适。这些并发症归因于假体设计不当、固定技术、解剖异常和手术失误。本文回顾了最常见的并发症，并讨论了其原因及预防措施。
