Is there a difference in the type of pathogens that can cause surgical site infections/periprosthetic joint infections (SSIs/PJIs) between hip and knee arthroplasty?

Authors: Karan Goswami, Hannah Groff
RECOMMENDATION: There is limited evidence to support a difference in the organism profi le causing SSIs and PJIs between hip and knee arthroplasty. Isolated studies have reported an increased prevalence of Streptococcal and culture-negative PJI around the knee, whereas, Staphylococcal, Enterococcal, Pseudomonal PJIs may be more prevalent around the hip. Further work regarding the diff erent fl ora in these respective body regions is needed, as it may determine antibiotic selection.
LEVEL OF EVIDENCE: Limited
DELEGATE VOTE: Agree: 92%, Disagree: 4%, Abstain: 4% (Super Majority, Strong Consensus)
