Introduction Isolated acetabular revision with the retention of a well-fixed and aligned femoral component is the priority treatment method in aseptic acetabular loosening. The aim of the research was to predict the survival rate of a well-fixed and aligned femoral component retained during the isolated acetabular revision surgery. Material and methods We used the survival tables and the Kaplan-Meier method to create the survival curves. The object of the study was the database of 44 patients (45 interventions) who underwent isolated acetabular revision surgeries with their well-fixed and aligned femoral components that was retained. The average age of the patients was 59.5 [50; 69.5] years. The ratio of women to men was 25:19, respectively. The observation period was 1374 days. The creation of tables and graphs was carried out in Statistica 13.3 software package. Results The survival rate of the retained well-fixed and aligned femoral component in isolated acetabular revision within the period up to 4 years was high and amounted to 0.9524 ± 0.03. The probability density and the hazard rates were 0.0017 and 0.00320, respectively. Discussion The retention of a well-fixed and aligned stem in acetabular revision features high survival of the components as well as a low risk of endoprosthesis failure within 3 to 4 years. This fact confirms the need to maintain a stable and correctly oriented stem to reduce the surgical trauma, obtain good functional results and reduce rehabilitation terms. Conclusion Isolated acetabular revision in isolated aseptic cup loosening is a priority method of surgical treatment with a low risk of complications in the postoperative period.Kseniia P.
