1. A method of implanting an acetabular implant, comprising:
fixing an acetabular shell to a mounting surface on an acetabulum, the acetabular shell having an inner surface and a lip portion defining an opening;
coupling an engagement portion of a fitting ring to an edge portion of a liner such that an alignment portion of the fitting ring extends radially outward from the liner;
inserting the liner into the opening such that the alignment portion engages the lip portion of the acetabular shell, wherein engaging the alignment portion to the lip portion of the acetabular shell maintains the liner at a predetermined distance from the inner surface; and
applying a driving force to the liner, toward the acetabular shell, to push the liner into engagement with the inner surface of the acetabular shell such that the liner and the acetabular shell are in an assembled state, wherein application of the driving force flexes the fitting ring against the acetabular shell to disengage the fitting ring from the assembled acetabular shell and liner.
