ABSTRACT:
An acetabular cup assembly for use with a femoral implant. The cup assembly includes an outer shell, a bearing liner configured to fit into a cavity in the shell, a generally annular retaining ring and a locking ring configured to hold the retaining ring in the shell adjacent the bearing liner. The locking ring is slidable between locked and free configurations, with at least part of the locking ring being formed as a closed loop to prevent radial contraction of the locking ring inner surface as the locking ring is slid between the free and locked configurations. At least one small circumferential rib is formed on the outer surface of the locking ring to engage a corresponding circumferential groove in the shell when the locking ring is installed therein in the locked configuration.
