Currently, there exists a paucity of literature about the impact of prior knee arthroscopy on subsequent total knee arthroplasty (TKA). The purpose of this study was to compare outcomes of patients undergoing TKA after prior knee arthroscopy with a matched cohort of control subjects with primary osteoarthritis and no history of arthroscopy.
We reviewed patients who underwent primary TKA at our academic center from January 2011 to December 2017. Of these, we included 68 patients (70 knees) that were performed TKA following knee arthroscopy. The groups were split by sex, age to within 6 years, and body mass index within 5 kg/m. A 1:2 matching algorithm was applied. Outcome measures included surgical time, intraoperative estimated blood loss, Oxford Knee Score, range of movement, complications, and revision rate.
This study had limited inclusion and exclusion criteria and a well-controlled intervention.
This clinical trial is expected to determine whether prior knee arthroscopy is associated with reduced functional outcomes or increased risks of revision and complications following TKA.
This study protocol was registered in Research Registry (researchregistry5413).
目前，关于既往膝关节镜检查对随后全膝关节置换术（TKA）影响的文献较少。本研究的目的是比较既往接受过膝关节镜检查的患者行TKA后的结果与一组匹配的原发性骨关节炎且无关节镜检查史的对照受试者的结果。
我们回顾了2011年1月至2017年12月在我们学术中心接受初次TKA的患者。其中，我们纳入了68例（70膝）在膝关节镜检查后行TKA的患者。根据性别、年龄相差6岁以内和体重指数相差5kg/m²进行分组。应用1:2匹配算法。结果指标包括手术时间、术中估计失血量、牛津膝关节评分、活动范围、并发症和翻修率。
本研究的纳入和排除标准有限，且干预措施控制良好。
本临床试验有望确定既往膝关节镜检查是否与TKA后功能结果降低或翻修及并发症风险增加相关。
本研究方案已在研究注册库（researchregistry5413）注册。
