人工髋膝置换术后慢性疼痛原因分析

Etiology of the chronic pain after artificial hip and knee replacement

人工髋、膝关节置换（TKA，THA）是治疗晚期髋、膝关节病变的有效方法，临床10年随访的结果显示，其有效率达92％～98％。然而，疼痛，既是髋、膝关节置换手术的主要适应证，也是人工髋、膝关节置换术的常见并发症。疼痛也是骨关节科的一个普遍的、容易被忽视的问题。人工关节置换术后出现经久不愈的疼痛，预示手术可能失败。人工髋、膝关节置换术后发生慢性持续疼痛的原因虽各有不同，但在大方向分类上，髋膝关节置换术后慢性疼痛有许多一致性，同时在一些具体原因上也有一定相关性，故将两者合并回顾。

Chronic pain after hip and knee replacement is common but easily overlooked. The etiology and mechanism of chronic pain are more complex than that of other complications after hip and knee replacement. In this article, the definition, epidemiology, reason analysis, conclusion and prospect of chronic pain after hip and knee replacement are reviewed and investigated. Based on the summary and analysis of the present data, a comprehensive and clear understanding of chronic pain after hip and knee replacement is expected, and the development of treatment plans is assisted.
