A national database was queried for patients who underwent TKA following ipsilateral knee arthroscopy. Three cohorts were created: TKA within 6 months of knee arthroscopy (n=681), TKA between 6 months and 1 year after knee arthroscopy (n=1301) and TKA between 1 and 2 years after knee arthroscopy (n=1069). An age-matched control group of TKA without prior knee arthroscopy was also created (n=37,235). The incidences of infection (OR 2.0, P=0.004), stiffness (OR 2.0, P=0.001) and VTE (OR 1.6, P=0.047) were higher in patients who underwent TKA within 6 months after knee arthroscopy compared to controls. There was no increase in complications when TKA was performed more than six months after knee arthroscopy.
对国家数据库进行查询，以获取同侧膝关节镜检查后接受全膝关节置换术（TKA）的患者信息。创建了三个队列：膝关节镜检查后6个月内进行TKA的患者（n = 681）、膝关节镜检查后6个月至1年进行TKA的患者（n = 1301）以及膝关节镜检查后1至2年进行TKA的患者（n = 1069）。还创建了一个年龄匹配的未进行过膝关节镜检查的TKA对照组（n = 37,235）。与对照组相比，膝关节镜检查后6个月内接受TKA的患者感染发生率（比值比[OR] 2.0，P = 0.004）、僵硬发生率（OR 2.0，P = 0.001）和静脉血栓栓塞（VTE）发生率（OR 1.6，P = 0.047）更高。膝关节镜检查后超过6个月进行TKA时，并发症没有增加。
