We analyzed the data for primary total hip arthroplasty (THA) in the Korean nationwide database to assess (1) the epidemiology and national trends of bearing surface usage in THAs and (2) the prevalence of each type of bearing surface according to age, gender, hospital type, primary payer, and hospital procedure volume.
A total of 30,881 THAs were analyzed using the Korean Health Insurance Review and Assessment Service database for 2007 through 2011. Bearing surfaces were sub-grouped according to device code for national health insurance claims and consisted of ceramic-on-ceramic (CoC), metal-on-polyethylene (MoP), ceramic-on-polyethylene (CoP), and metal-on-metal (MoM). The prevalence of each type of bearing surface was calculated and stratified by age, gender, hospital type, primary payer, and procedure volume of each hospital.
CoC was the most frequently used bearing surface (76.7%), followed by MoP (11.9%), CoP (7.3%), and MoM (4.1%). The proportion of THAs using a CoC bearing surface increased steadily from 71.6% in 2007 to 81.4% in 2011, whereas the proportions using CoP, MoP, and MoM bearing surfaces decreased. The order of prevalence was identical to that in the general population regardless of age, gender, hospital type, primary payer, and hospital procedure volume.
The trends and epidemiology of bearing surface usage in THAs in Korea are different from those in other countries, and the CoC bearing surface is the most prevalent articulation. In future, the results of a large-scale study using nationwide data of THAs involving a CoC bearing surface will be reported in Korea.
我们分析了韩国全国性数据库中初次全髋关节置换术（THA）的数据，以评估（1）THA中承重面使用的流行病学和全国趋势，以及（2）根据年龄、性别、医院类型、主要支付方和医院手术量划分的每种承重面类型的患病率。
使用韩国健康保险审查与评估服务数据库，对2007年至2011年期间的30881例THA进行了分析。根据国家健康保险索赔的设备代码对承重面进行亚组划分，包括陶瓷对陶瓷（CoC）、金属对聚乙烯（MoP）、陶瓷对聚乙烯（CoP）和金属对金属（MoM）。计算每种承重面类型的患病率，并按年龄、性别、医院类型、主要支付方和各医院的手术量进行分层。
CoC是最常用的承重面（76.7%），其次是MoP（11.9%）、CoP（7.3%）和MoM（4.1%）。使用CoC承重面的THA比例从2007年的71.6%稳步上升至2011年的81.4%，而使用CoP、MoP和MoM承重面的比例则下降。无论年龄、性别、医院类型、主要支付方和医院手术量如何，患病率顺序与普通人群相同。
韩国THA中承重面使用的趋势和流行病学与其他国家不同，CoC承重面是最普遍的关节连接方式。未来，韩国将报告一项使用涉及CoC承重面的THA全国性数据的大规模研究结果。
