An acetabular implant for hip arthroplasty includes an acetabular shell to be attached to an acetabulum. The acetabular shell includes an inner surface defining a shell cavity and having a tapered shell section. The acetabular shell includes a tool interlocking structure that mates with a shell insertion tool to inhibit rotation relative to the shell insertion tool. The acetabular shell includes a snap-fit receiver. An acetabular liner is sized and shaped to be disposed in the shell cavity of the acetabular shell. The acetabular liner including an outer surface having a tapered liner section corresponding to the taper of the tapered shell section and engages the tapered shell section to inhibit movement of the acetabular liner relative to the acetabular shell. The acetabular liner includes a snap-fit retainer received by the snap-fit receiver of the acetabular shell to form a snap-fit connection between the acetabular liner and the acetabular shell.
