Aim

Periprosthetic joint infections (PJI) and surgical site infections (SSI) are one of the most severe complications in joint arthroplasty. Decolonization measures prior to elective orthopedic surgeries have shown to reduce the risk of infection especially in patient identified as carriers of S. aureus. However additional screening measures can be difficult to implement in daily routine.

The objective was to study the influence of universal decolonization with polihaxanid on SSI rates.

Method

Between January 2017 and December 2018 patients scheduled for hip or knee joint arthroplasty in 5 participating orthopedic centers received polyhexanid containing decolonization set consisting of oral, nasal and wipes. Patients were instructed to perform a 5 day decolonization regimen 4 days prior to surgery. SSIs were recorded according to modified CDC criteria for a surveillance period of 90days after surgery.

Aim

Late acute prosthetic joint infections (PJI) treated with surgical debridement and implant retention (DAIR) have a high failure rate. The aim of our study was to evaluate treatment outcome in late acute PJIs treated with DAIR versus implant removal.

Method

In a large multicenter study, late acute PJIs were retrospectively evaluated. Failure was defined as: PJI related death or the need for prosthesis removal or suppressive antibiotic therapy because of persistent or recurrent signs of infection. Late acute PJI was defined as < 3 weeks of symptoms more than 3 months after the index surgery.

Aim

Debridement, antibiotics and implant retention (DAIR) is the recommended treatment for all acute prosthetic joint infections (PJI). However, the efficacy of DAIR and identification of risk factors for failure in patients with late acute PJI, is not well described.

Method

Patients diagnosed with late acute PJI between 2005 and 2015 were retrospectively evaluated. Late acute PJI was defined as the development of acute symptoms (≤ 3 weeks) occurring ≥ 3 months after arthroplasty. Failure was defined as: i) the need for implant removal, ii) infection related death, iii) the need for suppressive antibiotic therapy due to persistent signs of infection and/or iv) relapse or reinfection during follow-up.

Aim

Periprosthetic joint infections (PJI) are a rare, but devastating complication. Diagnostic approaches to PJI vary greatly between different centers. Most commonly tissue biopsies and synovial fluid sampling are recommended for identification pathogens causing PJI. However, sensitivity and specificity of those techniques have been shown to be highly dependent on preanalytical factors like time and conditions of transportation, location of sampling, as well as analytical approaches and prolonged incubation for up to 14days. Sonication of explanted orthopedic devices has been shown to be more than only an addition in the diagnosis of PJI. The goal of this study was to evaluate the diagnostic value of sonication in PJI.

Method

Retrospective cohort analysis of orthopedic samples sent for sonication from 29 surgical centers between 06/2014–04/2017. Until 07/2015 samples were plated on Columbia-, MacConkey-, Chocolate- and Schaedler agar*, incubated aerobically and anaerobically for up to 14 days.

In 07/2015 an additional enrichment of 10ml per aerobic and anaerobic blood culture bottles* was introduced. The bottles were also incubated up to 14days and plated immediately if growth was detected.
