A higher failure rate has been reported in haematogenous periprosthetic joint infection (PJI) compared to non-haematogenous PJI. The reason for this difference is unknown. We investigated the outcome of haematogenous and non-haematogenous PJI to analyze the risk factors for failure in both groups of patients. Episodes of knee or hip PJI (defined by the European Bone and Joint Infection Society criteria) treated at our institution between January 2015 and October 2020 were included in a retrospective PJI cohort. Episodes with a follow-up of > one year were stratified by route of infection into haematogenous and non-haematogenous PJI. Probability of failure-free survival was estimated using the Kaplan-Meier method, and compared between groups using log-rank test. Univariate and multivariate analysis was applied to assess risk factors for failure.Aims
Methods
To investigate the outcomes of treatment of streptococcal periprosthetic
joint infection (PJI) involving total knee and hip arthroplasties. Streptococcal PJI episodes which occurred between January 2009
and December 2015 were identified from clinical databases. Presentation
and clinical outcomes for 30 streptococcal PJIs in 30 patients (12
hip and 18 knee arthroplasties) following treatment were evaluated
from the medical notes and at review. The Kaplan-Meier survival method
was used to estimate the probability of infection-free survival.
The influence of the biofilm active antibiotic rifampin was also
assessed.Aims
