Conditions
Brief summary
This study aims to evaluate the mid-term clinical and radiological outcomes of using porous acetabular components in combination with trabecular metal augments in patients undergoing revision hip replacement surgery. These patients had previously received hip implants that failed due to significant bone loss. The research focuses on assessing joint function, radiographic results, postoperative complications, and how long the new implants last (implant survivorship). In addition, the study explores whether different types of bone defects, classified by the Paprosky system, are associated with better or worse outcomes. The findings will help improve decision-making in complex hip revision surgeries involving major bone defects.
Interventions
This study is a retrospective analysis of prospectively collected clinical and radiological data from a departmental registry of patients who underwent revision total hip arthroplasty due to aseptic loosening and severe acetabular bone loss
The registry was maintained prospectively and included clinical cases of patients consecutively operated on in the 2nd Department of Large Joint Arthroplasty at the N.N. Priorov Center from 2016 to 2022. Porous acetabular components combined with trabecular
This study is a retrospective analysis of prospectively collected clinical and radiological data from a departmental registry of patients who underwent revision total hip arthroplasty due to aseptic loosening and severe acetabular bone loss The registry was maintained prospectively and included clinical cases of patients consecutively operated on in the 2nd Department of Large Joint Arthroplasty at the N.N. Priorov Center from 2016 to 2022. Porous acetabular components combined with trabecular metal augments were used. Clinical and radiographic data were collected from the time of surgery and during standardized follow-up visits at 3 months, 1 year, 2 years, and 5 years. When in-person follow-up was not possible, remote assessment was conducted via telephone and review of submitted radiographs. Outcomes collected included Harris Hip Score (HHS), VAS, WOMAC, complications, implant survivorship, and radiological signs of loosening. The maximum follow-up duration was 9 years, with a mean follow-up of 4.9 years. The current analysis of the dates was initiated in 2025 to evaluate mid-term outcomes (clinical scores, radiological assessment, complications, and implant survival).
