摘要：

A joint replacement component comprising a metal tray (3) and polymer liner (27). The metal tray having screw holes (7a, 7b) for fixation with screws (9) to bone, and a circumferential rim or wall (15) with a smooth inner surface (21). The liner having a flexible sealing ridge (39) around its entire periphery for tray engagement, forming a fluid-tight seal between the liner and tray. The liner having a locking mechanism comprised of tabs (35) at longitudinal ends of the liner, which engage grooves (23) in the tray's front and rear. Following tray fixation to the resected skeletal structure, a surgeon installs the liner within the tray by angling the liner, inserting first tab into its respective groove, pressing the liner downwardly into the tray causing the liners opposing tab to engage its respective groove, snap-locking the liner within the tray, and simultaneously sealing the liner to the tray by the flexible sealing ridge.
