僵硬是原发性全膝关节置换术最常见的早期局部并发症，约影响6 - 7%的手术患者。在过去的20年里，由于患者和医生期望更好的术后功能预后，全膝关节置换术后僵硬度的定义在活动弧度的限制方面发生了变化。在手术3 - 4个月的麻醉下轻柔的操作可以改善大多数患者的活动范围。然而，大约1%的患者，包括那些已经过了操作窗口期的患者，将需要进一步的手术干预，其中可能包括关节镜和粘连溶解，开放式清创和聚乙烯插入物交换，或修改一个或多个组件。这篇综述将集中描述问题的病因和不同的手术干预对全膝关节置换术后僵硬的结果。
Stiffness is the most prevalent early local complication of primary total knee replacement, affecting approximately 6 to 7% of patients undergoing surgery. The definition of stiffness after total knee replacement in terms of restriction of the arc of motion has evolved in the last 2 decades as patients and physicians expect better postoperative functional outcomes. Gentle manipulation under anesthesia within 3 to 4 months of surgery improves the range of motion in most patients. However, approximately 1% of patients, including those in which the window for manipulation has passed, will require further surgical interventions, which may include arthroscopy with lysis of adhesions, open debridement with exchange of the polyethylene insert, or revision of one or more components. This review will focus on describing the etiology of the problem and the results of the different surgical interventions for stiffness after total knee replacement.
