IN THIS RETROSPECTIVE COMPARATIVE CASE-CONTROL SERIES, THE AUTHORS COMPARE ACETABULAR IMPACTION BONE GRAFTING (AIBG) AND TRABECULAR METAL (TM) ACETABULAR RECONSTRUCTION FROM A SINGLE INSTITUTION OVER A 5- TO 10-YEAR PERIOD. THE AIM WAS TO DETERMINE ANY SIGNIFICANT DIFFERENCE IN RADIOLOGICAL OR CLINICAL OUTCOMES BETWEEN BOTH ACETABULAR SURGICAL REVISION STRATEGIES. THIS ARTICLE FOCUSES ON ACETABULAR RECONSTRUCTION DURING COMPETITOR CUP REVISION. IMPLANTED PRODUCTS: THE INITIAL IMPLANTS FOR THAS WERE A COMPETITOR CUP AND LINER WITH A CHARNELY FEMORAL COMPONENT. IF A CONCOMITANT FEMORAL REVISION WAS INDICATED, EITHER A DEPUY NONMODULAR SOLUTION STEM OR A DEPUY MODULAR RECLAIM SYSTEM WAS USED. THERE WERE 2 REVISIONS OF AN ASR HRA INCLUDED WITHIN THE STUDY, ASSIGNED TO THE IMPACTION BONE GRAFTING GROUP. THE REASONS FOR CUP REVISION INCLUDED ACETABULAR OSTEOLYSIS AND SEPSIS (4 CASES). THERE WAS ONE PERIPROSTHETIC FRACTURE FOR A CHARNLEY STEM THAT WAS REVISED. THE REMAINING REASONS FOR CHARNLEY STEM REVISION (33) WERE UNSPECIFIED INSTABILITY, FEMORAL OSTEOLYSIS, AND SEPSIS. THE FEMORAL OSTEOLYSIS IS ATTRIBUTED TO THE COMPETITOR POLYETHYLENE LINER. IMPLANTED PRODUCTS AT REVISION WERE A COMPETITOR CUP AND LINER AND A DEPUY STEM AND HEAD. REVISION RESULTS: THIS ARTICLE DISCUSSES THE OUTCOMES OF REVISION FOR COMPETITOR CUPS AND LINERS AND WILL THEREFORE NOT BE INCLUDED IN THIS COMPLAINT. OF THE STEMS AND HEADS REVISED, 1 NEEDED RESECTION ARTHROPLASTY FOR SEPSIS AND ANOTHER WAS REVISED AT ANOTHER INSTITUTION FOR UNKNOWN REASONS. CAPTURED IN THIS COMPLAINT: 1 ASR HEMIARTHROPLASTY FOR OSTEOLYSIS AND SEPSIS 33 CHARNLEY STEMS FOR SEPSIS, AND UNSPECIFIED INSTABILITY. THE AUTHORS DO NOT ATTRIBUTE THE JOINT INSTABILITY TO A SPECIFIC PRODUCT OR LOCATION. THE OSTEOLYSIS LISTEN IN THE ARTICLE IS ATTRIBUTED TO THE COMPETITOR POLYETHYLENE LINER. 33 DEPUY FEMORAL HEADS FOR SEPSIS, AND UNSPECIFIED INSTABILITY. THE AUTHORS DO NOT ATTRIBUTE THE JOINT INSTABILITY TO A SPECIFIC PRODUCT DEFECT OR LOCATION. THE OSTEOLYSIS LISTEN IN THE ARTICLE IS ATTRIBUTED TO THE COMPETITOR POLYETHYLENE LINER. 1 FEMORAL STEM, HEAD, AND SLEEVE RE-REVISED FOR SEPSIS. 1 FEMORAL STEM, HEAD, AND SLEEVE RE-REVISED FOR UNKNOWN CAUSES.
