Abstract
A fitting ring can be provided that is attachable to an edge of a liner for an acetabular shell. The fitting ring can include an alignment portion shaped or configured to engage a lip portion of the acetabular shell as the liner is inserted into the acetabular shell to center the liner and correct any pivoting of the liner relative to the acetabular shell. A driving force can be applied to the liner to drive the liner into the acetabular shell while the fitting ring guides the liner as the liner is inserted into the acetabular shell. Driving the liner into the acetabular shell can also cause the fitting ring to disengage from the liner.
