Abstract
An acetabular cup assembly includes a shell and a liner. The shell has an inner surface, an outer surface, a face positioned at an upper end of the shell, and an apex positioned at a lower end of the inner surface. The inner surface includes a tapered inner wall and a plurality of inwardly-facing recesses provided along the inner surface adjacent the face. The plurality of inwardly-facing recesses include a main portion and an asymmetrically-extending portion. Each of the asymmetrically-extending portions extend circumferentially in one direction resulting in the recesses having an asymmetric shape. The segmented portion of the tapered inner wall has a wide portion between the asymmetrically-extending portion and the face and a narrower portion between the asymmetrically-extending portion and the adjacent inwardly-facing recess. The liner is adapted to fit within the shell and engage the inner surface of the shell establishing an interference fit.
