The risk factors for instability after a total hip revision are not the same as those after a primary procedure. The extent of the soft-tissue dissection is probably the most important variable since head size and trochanteric nonunion are related to "soft-tissue tension." Modular acetabular components with an elevated rim help to stabilize a hip undergoing a revision procedure.
Alberton et al. (2002) studied this question.
