Background: Total hip arthroplasty (THA) is one of the most common surgical interventions performed to restore function and alleviate discomfort in patients with severe hip joint diseases. Nonetheless, THA carries a risk of postoperative dislocation which continues to remain a significant concern. Dislocation risks may be lowered with the new design dual mobility cups that attempt to balance range of motion and stability within the joint components. This study was conducted ‘to assess the functional outcomes and complication rates associated with the use of dual mobility cups in patients undergoing primary total hip arthroplasty’.
Methods: A prospective observational study was carried out from January 2023 to January 2024 on a sample of 59 patients who underwent primary THA with dual mobility cup implantation. ‘Patient demographics, comorbidities, surgical approach, fixation type, and postoperative complications were recorded’. Functional outcomes were measured using Harris Hip Scores over a follow-up period of up to one year.
Results: Dual mobility cups showed promising functional outcomes, with a notable improvement in mobility and pain reduction in most patients. The complication rate was low, with no cases of dislocation reported during the follow-up period. Most patients reported high satisfaction levels and returned to independent daily activities.
Conclusion: The application of dual mobility cups in primary total hip arthroplasty enhances functional outcomes, improves stability, and minimizes complications. These findings support their continued use, especially in populations at higher risk of instability.
