To Assess the Outcomes of Total Hip Arthroplasty Using Dual Mobility Implants

Abstract

Background: A common and reasonably priced treatment, total hip arthroplasty (THA) is well-known for its positive results in treating advanced hip osteoarthritis and associated disorders. Although there has been a 9.2% revision rate in Pakistan due to cup shell fractures, dual mobility implants, which are being utilised more and more to lower the risk of dislocation, have shown promise. Objective: To assess the outcomes of total hip arthroplasty using dual mobility implants. Study design: Descriptive study Place and Duration: This study was conducted in, Muhammad Medical College, Ibn-e-Sina University Hospital Mirpurkhas Pakistan from January 2022 to January 2025 Methodology: 80 patients who had total hip arthroplasty (THA) with dual mobility implants participated in this descriptive study, which was carried out at the Department of Orthopaedic Surgery. Clinical evaluations and Harris Hip Scores were used to evaluate pre- and postoperative results, and SPSS version 28.0 was used to analyse the data. With a paired t-test and dependent stratified t-test by gender, we established statistical significance at p < 0.05. Results: The total number of patients was 80, aged 61.05 years on average, with 65% of them being male. The most common reason for performing THA was avascular necrosis of the femoral head. Surgical dislocations were not encountered and both sexes’ Harris Hip Scores improved (p < 0.001) statistically. Conclusion: The study found that there was a statistically significant difference in preoperative and postoperative evaluations of the Harris Hip Score. Moreover, no dislocations were observed after dual mobility total hip replacement.
