PURPOSE The aim of the present study was to evaluate the impact of the coronavirus (COVID-19) pandemic on joint arthroplasty service in Europe by conducting an online survey of arthroplasty surgeons. METHODS The survey was conducted in the European Hip Society (EHS) and the European Knee Associates (EKA). The survey consisted of 20 questions (single, multiple choice, ranked). Four topics were addressed: (1) origin and surgical experience of the participant (four questions); (2) potential disruption of arthroplasty surgeries (12 questions); (3) influence of the COVID-19 pandemic on the particular arthroplasty surgeon (four questions); (4) a matrix provided 14 different arthroplasty surgeries and the participant was asked to state whether dedicated surgery was stopped, delayed or cancelled. RESULTS Two-hundred and seventy-two surgeons (217 EHS, 55 EKA) from 40 different countries participated. Of the respondents, 25.7% stated that all surgeries were cancelled in their departments, while 68.4% responded that elective inpatient procedures were no longer being performed. With regard to the specific surgical procedures, nearly all primary TJA were cancelled (92.6%) as well as aseptic revisions (94.7%). In most hospitals, periprosthetic fractures (87.2%), hip arthroplasty for femoral neck fractures and septic revisions for acute infections (75.8%) were still being performed. CONCLUSION During the current 2020 COVID-19 pandemic, we are experiencing a near-total shutdown of TJA. A massive cutback was observed for primary TJA and revision TJA, even in massively failed TJA with collapse, dislocation, component failure or imminent dislocation. Only life-threatening pathologies like periprosthetic fractures and acute septic TJA are currently undergoing surgical treatment. LEVEL OF EVIDENCE V.

COVID-19 大流行期间欧洲关节置换术服务的中断：欧洲髋关节协会 (EHS) 和欧洲膝关节协会 (EKA) 的在线调查。

目的本研究的目的是通过对关节置换术外科医生进行在线调查，评估冠状病毒（COVID-19）大流行对欧洲关节置换术服务的影响。方法 这项调查是在欧洲髋关节协会 (EHS) 和欧洲膝关节协会 (EKA) 中进行的。该调查包括 20 个问题（单选、多选、排名）。讨论了四个主题：（1）参与者的出身和手术经历（四个问题）；(2) 关节置换手术的潜在干扰（12 个问题）；(3) COVID-19大流行对特定关节置换术外科医生的影响（四个问题）；(4) 矩阵提供了 14 种不同的关节置换手术，参与者被要求说明专用手术是否停止、延迟或取消。结果 来自 40 个不同国家的 272 名外科医生（217 名 EHS，55 名 EKA）参加了研究。在受访者中，25.7%的人表示其科室的所有手术都被取消，而68.4%的人则表示不再进行择期住院手术。至于具体的手术方式，几乎所有原发性TJA（92.6%）以及无菌翻修（94.7%）都被取消。大多数医院仍在进行假体周围骨折（87.2%）、股骨颈骨折髋关节置换术和急性感染脓毒症翻修术（75.8%）。结论 在当前的 2020 年 COVID-19 大流行期间，我们正经历 TJA 几乎完全关闭。观察到初次 TJA 和翻修 TJA 的大幅缩减，甚至在因塌陷、脱位、组件故障或即将脱位而严重失败的 TJA 中也是如此。目前只有假体周围骨折和急性化脓性 TJA 等危及生命的疾病正在接受手术治疗。证据水平 V.
