Comparison of Outcomes Between Modular Dual Mobility and Conventional Hip Implants in Primary, Elective Total Hip Arthroplasty

MDM patients experience lower rates of dislocation compared with those receiving conventional implants. Despite worse clinical outcomes and increased all-cause emergency department utilization in the MDM group, multivariate regression suggests that these outcomes were associated with the implant being used in an older, sicker population instead of the implant itself. The results suggest similar overall outcomes and a lower dislocation rate for patients who received an MDM hip.
