    IT WAS REPORTED IN THE JOURNAL ARTICLE THAT THE PURPOSE OF THE STUDY WAS TO INVESTIGATE THE POSTOPERATIVE FUNCTIONAL OUTCOMES OF 2 GROUPS OF PRIMARY AND REVISION THA, WHEN REVISION PROCEDURES WERE PERFORMED USING A GLUTEAL-SPARING EXTENDED POSTERIOR APPROACH. THE STUDY ENROLLED 51 PRIMARY TOTAL HIP PATIENTS AND 21 REVISION TOTAL HIP PATIENTS. ALL PRIMARY THAS WERE PERFORMED VIA POSTERIOR APPROACH USING A PRESS-FIT TRILOGY ACETABULAR COMPONENT AND A CEMENTED COLLARLESS TAPERED FEMORAL STEM. ALL REVISION THAS WERE PERFORMED VIA POSTERIOR APPROACH AS WELL. IF AN ACETABULAR REVISION WAS PERFORMED, A TRILOGY OR TM MODULAR / TMARS COMPONENT. IN THE CASE OF POOR BONE QUALITY OR CONTACT, 2-3 SCREWS WERE IMPLANTED AS WELL. IF A FEMORAL STEM REVISION WAS PERFORMED, A COLLARLESS POLISHED TAPERED STEM OR ZIMMER MODULAR REVISION STEM WAS USED. REVISION STEMS WERE CEMENTED THROUGH A CEMENT-WITHIN-CEMENT EXCHANGE, IMPACTION BONE GRAFTING, OR BY CEMENTING ALONG OF A LONG STEM. THE PRIMARY GROUP HAD A MEAN AGE OF 69.2 YEARS AT TIME OF SURGERY (RANGE 64.2-74.2), AND THE REVISION GROUP HAD A MEAN AGE OF 72.8 YEARS AT THE TIME OF SURGERY (RANGE 66.8-78.8). FOLLOW-UP WAS CONDUCTED AT 3 MONTHS AND 1 YEAR POSTOPERATIVELY. THE STUDY REPORTED 1 PATIENT WHO HAD AN INITIAL THA DUE TO ACUTE ABC ACETABULAR FRACTURE WAS ENROLLED IN THE REVISION COHORT DUE TO LOOSENING.
