This study reviewed the outcome of a single institution's experience with 910 primary total hip arthroplasties using 3 different types of modular, first-generation, hemispheric porous-coated cups. The population included 433 Arthopor, 394 ACS Triloc+, and 83 Harris-Galante components. Among 168 total hip arthroplasties that have undergone acetabular revision, aseptic loosening has occurred in 20 cases. Using liner or cup revision for any reason as an end point, we found that 15-year survivorship was 74.9% +/- 6.2% (95% confidence interval) for the Arthopor cups, 70.1% +/- 7.0% for the ACS Triloc+ components, and 89.3% +/- 10.3% for the Harris-Galante cups (P = .02, log rank). Despite a high incidence of revision for polyethylene wear-related complications and occasional late porous-coating delamination, survivorship using revision for aseptic loosening as an end point exceeded 95% at 15 years for all 3 cup designs.
本研究回顾了一家机构使用3种不同类型的模块化第一代半球形多孔涂层髋臼杯进行910例初次全髋关节置换术的结果。研究对象包括433个Arthopor杯、394个ACS Triloc+杯和83个Harris-Galante杯。在168例接受髋臼翻修的全髋关节置换术中，有20例发生无菌性松动。以因任何原因进行衬垫或髋臼杯翻修为终点，我们发现Arthopor杯15年生存率为74.9%±6.2%（95%置信区间），ACS Triloc+杯为70.1%±7.0%，Harris-Galante杯为89.3%±10.3%（P = 0.02，对数秩检验）。尽管因聚乙烯磨损相关并发症进行翻修的发生率较高，且偶尔会出现晚期多孔涂层分层，但以无菌性松动翻修为终点，所有3种髋臼杯设计在15年时的生存率均超过95%。
