Periprosthetic Joint Infection Risk Increases in Patients Having Reoperations Within One Year of Hip Replacement
For Immediate Release
November 9, 2019
Dallas – A study receiving the Lawrence D. Dorr Surgical Techniques & Technologies Award at the 2019 AAHKS Annual Meeting examined registry data to evaluate the risk of periprosthetic joint infection (PJI) in patients undergoing an aseptic reoperation within one year of a primary total hip arthroplasty (THA).
Ashton H. Goldman, MD explained that a control group of 15,357 patients with THAs not requiring reoperation within the first year were identified. Dr. Goldman and co-authors, Douglas Osmon, MD, Arlen D. Hanssen, MD, Mark W. Pagnano, MD, Daniel J. Berry, MD and Matthew P. Abdel, MD divided study patients into two groups – those who had the reoperations in less than 90 days and those from 91 days to one year.
The study found that, “aseptic reoperations within the first year following primary THA lead to a 8 to 13-fold increased risk of subsequent PJI,” and that the risk was similar whether the reoperation occurred early or later within the year following surgery.
Lawrence D. Dorr, MD presented his namesake award to Dr. Goldman following the presentation.
