Offering a broad selection of shell and liner configurations, the Trilogy Acetabular System is designed to help restore kinematic function by addressing the challenges associated with primary and revision acetabular reconstruction. The full-hemisphere, modular system builds on the success of the Harris/Galante and HGP II Porous Acetabular Components. The complete range of sizes and options, combined with proven design features, makes it possible to select an acetabular component that meets both patient need and your preference.
