Longer operative time results in a higher rate of subsequent periprosthetic joint infection in patients undergoing primary joint arthroplasty
Journal of Arthroplasty Feb 15, 2019
Wang Q, et al. - Researchers retrospectively analyzed 17,342 primary unilateral total knee arthroplasty and total hip arthroplasty performed at a single institution between 2005 and 2016 to investigate the relationship between operative time and the risk of subsequent surgical site infection (SSI) and periprosthetic joint infection (PJI) in patients undergoing primary total joint arthroplasty (TJA). They noticed a significantly higher incidence of SSI and PJI among patients with an operative time of >90 minutes as compared to cases lasting between 60 and 90 minutes, and those lasting ≤60 minutes. They concluded a 25% increased risk of subsequent PJI with each 20-minute increment in operative time.
