Gausden EB, Shirley MB, Abdel MP, et al. - Researchers herein assessed patients who have an acute, traumatic wound dehiscence following total knee arthroplasty (TKA) in order to ascertain the risk of periprosthetic joint infection (PJI) and reoperation among them. At a single institution, a total of 16,134 primary TKAs were performed from January 2002 to December 2018. A traumatic wound dehiscence occurred in 26 patients (0.1%) within the first 30 days. Overall the risk of PJI was low after having a traumatic wound dehiscence, but relative to all other TKAs during the same period, the risk was much higher. Urgent IDCR and a course of postoperative antibiotics are recommended to lower the risk of PJI. Risk of PJI increases by 6.5-fold after a traumatic wound dehiscence.
