Purpose: The aim was to evaluate the functional outcome and dislocation rate at a minimum of 1-year follow-up following total hip replacement (THR) using Stryker modular dual mobility (MDM) X3 Mobile Bearing Hip System. Materials and Methods: This was a prospective study. The sample size was twenty patients who had secondary osteoarthritis hip with age <60 years; who had no debilitating disease, neurological motor disease, or any history of hip fracture or infection; and those who had underwent primary uncemented THR. They were evaluated clinically using the Western Ontario and McMaster Universities Arthritis Index (WOMAC) and Oxford Hip Score (OHS) and radiologically using routine radiographs. Results: The mean OHS at a minimum of 1-year follow-up was 40.40 ± 6.253, whereas WOMAC score was 93.85 ± 3.511. Correlational analysis of OHS and WOMAC score revealed very weak relationship (r = 0.165), and P = 0.486 was considered statistically not significant. Conclusion: The present study demonstrates that short-term follow-up of MDM THR is not worse than what is routinely used in the market.
