MDMs Used in Hip Replacement Show Low Rate of Instability after Surgery


Dallas, November 3, 2018 — A presentation at the 2018 American Association of Hip and Knee Surgeons Annual Meeting reported on patient outcomes of revision total hip arthroplasty (THA) that used modular dual mobility devices.

Ronald C. Huang, MD presented the results of the study, “Multicenter Evaluation of a Modular Dual Mobility Construct for Revision Total Hip Arthroplasty.” Dr. Huang and his co-authors Arthur L. Malkani, MD, Michael A. Mont, MD, William J. Hozack, MD, Steven F. Harwin, MD and Geoffrey H. Westrich, MD evaluated data from a multicenter retrospective cohort of 370 revision THAs to determine whether those using modular dual-mobilities could increase stability post-surgery. Some of the data studied included Harris Hip Scores, reoperation, loosening, infection, fractures, acetabular malposition, liner seating and screw placement.

The study concluded that “revision THAs with MDM constructs provided a very low rate of instability, good functional improvement and a low reoperation rate.”
