Comparing Standard Versus Extended Culture Duration in Acute Hip and Knee Periprosthetic Joint Infection.

CONCLUSION: Extended culture duration in acute hip and knee PJIs did not change the rate of culture-negative PJI, identify more patients with polymicrobial PJI, or improve the success of surgical treatment. The only difference was a higher incidence of P acnes growth, but contaminants or indolent chronic PJI cannot be excluded. Although extended culture growth may be indicated in acute shoulder arthroplasty PJI, its utility in hip or knee arthroplasty may be limited. Higher-level studies will be needed to address this in the future. PMID: 30431505 [PubMed - as supplied by publisher]
