Abstract：
UNASSIGNED: Arthroplasty registers can provide feedback information on the results of arthroplasties performed by a certain institution or surgeon. The use of real-world data to achieve real-world evidence can help evaluate the performance of the implants used and help counsel our patients. The main objective of our study was to determine the survivorship of the total knee implant we are currently using.
UNASSIGNED: A retrospective cohort study of patients who received a total knee arthroplasty from January 2009 to December 2020 in our hospital was conducted, using data from the Catalan arthroplasty registry and the Catalan health service database. Demographic and surgical data were analysed using the Kaplan-Meier method, log-rank test and Cox proportional hazards models with the R Project software (p < 0.05).
UNASSIGNED: A total of 1336 total knee arthroplasties were included in the study, of which 992 were women. The causes for revision included aseptic loosening (17), infection (29), instability (13), patellar implantation (13), arthrofibrosis (5) and quadriceps tendon rupture (1).The cumulative risk for revision at 5 years using the Kaplan-Meier method was 6.0% and at 10 years 6.5%. Considering gender, this risk was 7.0% and 7.5% at 5 and 10 years, respectively, in women and 3.3% in men, both at 5 and 10 years (p = 0.009). A higher risk for revision in women was seen, which is considered statistically significant (p = 0.012).
UNASSIGNED: Our survivorship results are comparable to those published in the literature, but with a higher revision risk in women that is only statistically significant for the whole group of reoperations and for patellar implantation, but not for the rest of the diagnoses.
UNASSIGNED: Level IV.

摘要：
■关节成形术寄存器可以提供有关由某个机构或外科医生进行的关节成形术的结果的反馈信息。使用真实世界的数据来获得真实世界的证据可以帮助评估所使用的植入物的性能，并帮助指导我们的患者。我们研究的主要目的是确定我们目前使用的全膝关节植入物的存活率。
■对2009年1月至2020年12月在我院接受全膝关节置换术的患者进行了回顾性队列研究，使用来自加泰罗尼亚关节成形术注册和加泰罗尼亚卫生服务数据库的数据。使用Kaplan-Meier方法分析人口统计学和手术数据，RProject软件的对数秩检验和Cox比例风险模型(p<0.05)。
■本研究共纳入了1336例全膝关节置换术，其中992人是女性。翻修的原因包括无菌性松动（17），感染（29），不稳定性（13），髌骨植入(13),关节纤维化（5）和股四头肌腱断裂（1）。使用Kaplan-Meier方法的5年修订累积风险为6.0％，10年修订累积风险为6.5％。考虑到性别,这一风险在5年和10年分别为7.0%和7.5%，分别,女性占3.3%，男性占3.3%，在5年和10年（p=0.009）。女性的翻修风险更高，这被认为是统计学上显著的(p=0.012)。
■我们的生存结果与文献中发表的结果相当，但女性的翻修风险较高，仅对整个再次手术组和髌骨植入组具有统计学意义，但不是其他的诊断。
■四级。
