Current Concepts and Technologies in Acetabular Cup Positioning for Primary Total Hip Arthroplasty

Background: Total hip arthroplasty (THA) is a broadly used surgical technique for treating hip joint arthritis, offering significant pain relief and improved mobility. For optimal results, the acetabular cup must be positioned precisely because incorrect positioning might result in wear and dislocation, among other issues. In addition to reviewing current advancements in enhancing accuracy and optimal location, the study sought to assess acetabular cup positioning in primary routine total hip replacements. Methods: A retrospective cohort study was carried out from June 2023 to May 2024. Two hundred individuals who had primary THA were included in the study. Data on patient demographics, surgical details, and acetabular cup positioning were collected and analyzed using SPSS software. Results: The mean age was 65.3 years, with a majority of males (55%). Osteoarthritis was the primary indication for surgery in 70% of cases. The posterior approach was used in 70% of surgeries, with 80% of implants being cementless. Radiographic analysis showed that 85% of acetabular cups were within the optimal range of 30-50 degrees for inclination angle, and 90% were within the optimal range of 5-25 degrees for anteversion angle. There was a significant variation in anteversion angles between the posterior and anterolateral approaches (p = 0.03). Conclusion: The study highlights the importance of accurate acetabular cup positioning in primary THA. The findings suggest that the surgical approach may influence cup positioning, emphasizing the need for meticulous surgical technique. The study contributes to improving outcomes in total hip arthroplasty by providing insights into acetabular cup positioning. Recommendations: Future research should focus on further refining surgical techniques to achieve more accurate acetabular cup positioning and assess the long-term effects on patient outcomes.
