Current techniques and new developments in acetabular revision surgery

Revision of a failed acetabular component is one of the most challenging aspects of revision hip arthroplasty. The revision hip surgeon must have a systematic approach to preoperative, operative and post-operative management. The majority of acetabular revisions can be performed using uncemented "jumbo" components, however severe bone loss can make reconstruction difficult. An advanced skill set including practical knowledge of extensile exposures, special techniques in removal of components, management of bone defects, and reimplantation of revision components, is essential. The various surgical options available to the revision surgeon are discussed in this article with particular focus on new techniques, instruments, materials and prostheses which may make this challenging area less complex to manage and may improve outcomes for patients in the future.
