This study reviewed the outcome of a Single institution's experience with 910 primary, total hit) 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.
