Should a Urinary Tract Infection Be Treated before a Total Joint Arthroplasty?

Periprosthetic joint infection (PJI) is one of the most serious complications after total joint arthroplasty (TJA). The prevalence of urinary tract infection (UTI) is common, particularly among elderly women, a group for whom TJA may be required. The association between preoperative UTI and increased risk of PJI after TJA is unclear. We reviewed key articles concerning the relationship between UTIs and PJI, and summarized recommendations of international consensus on PJI, which was established in Philadelphia in July of 2018. In addition, we distinguish between symptomatic UTI and asymptomatic bacteriuria, because their causative effects on PJI are quite different.
