Abstract. Introduction The paper presents a comparative analysis of routine screening methods and the EBJIS 2021 algorithm in detection of latent periprosthetic joint infection in patients admitted for revision knee arthroplasty due to aseptic loosening and after spacer implantation. Materials and methods Group 1 included 49 patients who underwent revision knee arthroplasty due to aseptic loosening, group 2 were 47 patients with PJI after spacer implantation. Results and discussion There were no significant differences between patient groups in terms of age, gender, and preoperative ESR and CRP levels. In 62.2 % of all cases, the aspirate was inappropriate for cytological examination; this fact limited its diagnostic value. The most frequently intraoperatively isolated pathogen in both groups was coagulase-negative staphylococci. However, in 70 % of cases these results were not diagnostically significant, and infection was diagnosed only in 8.2 % of cases in group 1 and 12.8 % in group 2. Moreover, the chances of isolating the pathogen from tissue biopsies were 5.6 times higher than from intraoperative aspirate (OR = 5.6, 95 % CI = 1.2-26.4). In case of negative preoperative aspirate, in almost 25 % of cases, pathogens were isolated from intraoperative tissues, 40.9 % of them were diagnostically significant. The chances of its detection increased 4.7 times in combined increase in ESR and CRP blood level (OR = 4.686, 95 % CI = 0.765-28.700). Using EBJIS 2021 criteria, infection was confirmed in more than 10 % of cases in each group, and the diagnostic significance of the criteria exceeded the significance of using routine screening methods. At a follow-up period of more than 2 years, the effectiveness of treatment was 95.3 %, while signs of infection were detected in 4.7 % of cases, regardless of the group. Conclusion EBJIS 2021 criteria are characterized by high diagnostic sensitivity and specificity and enable to identify periprosthetic joint infection in knee revision cases even in its latent form and to correct treatment tactics in patients without a history of PJI.

AbstractTotal knee arthroplasty is a widely successful procedure, but a small percentage of patients have a postoperative course complicated by periprosthetic joint infection (PJI). PJI is a difficult problem to diagnose and to treat, and the management of PJI differs, depending on the acuity of the infection. This paper discusses the established and newer technologies developed for the diagnosis of PJI as well as different treatment considerations and surgical solutions currently available.

Aims To describe the risk of periprosthetic joint infection (PJI) and reoperation in patients who have an acute, traumatic wound dehiscence following total knee arthroplasty (TKA). Methods From January 2002 to December 2018, 16,134 primary TKAs were performed at a single institution. A total of 26 patients (0.1%) had a traumatic wound dehiscence within the first 30 days. Mean age was 68 years (44 to 87), 38% (n = 10) were female, and mean BMI was 34 kg/m2 (23 to 48). Median time to dehiscence was 13 days (interquartile range (IQR) 4 to 15). The dehiscence resulted from a fall in 22 patients and sudden flexion after staple removal in four. The arthrotomy was also disrupted in 58% (n = 15), including a complete extensor mechanism disruption in four knees. An irrigation and debridement with component retention (IDCR) was performed within 48 hours in 19 of 26 knees and two-thirds were discharged on antibiotic therapy. The mean follow-up was six years (2 to 15). The association of wound dehiscence and the risk of developing a PJI was analyzed. Results Patients who sustained a traumatic wound dehiscence had a 6.5-fold increase in the risk of PJI (95% confidence interval (CI) 1.6 to 26.2; p = 0.008). With the small number of PJIs, no variables were found to be significant risk factors. However, there were no PJIs in any of the patients who were treated with IDCR and a course of antibiotics. Three knees required reoperation including one two-stage exchange for PJI, one repeat IDCR for PJI, and one revision for aseptic loosening of the tibial component. Conclusion Despite having a traumatic wound dehiscence, the risk of PJI was low, but much higher than experienced in all other TKAs during the same period. We recommend urgent IDCR and a course of postoperative antibiotics to decrease the risk of PJI. A traumatic wound dehiscence increases risk of PJI by 6.5-fold.

Aims The management of periprosthetic joint infection (PJI) after total knee arthroplasty (TKA) is challenging. The correct antibiotic management remains elusive due to differences in epidemiology and resistance between countries, and reports in the literature. Before the efficacy of surgical treatment is investigated, it is crucial to analyze the bacterial strains causing PJI, especially for patients in whom no organisms are grown. Methods A review of all revision TKAs which were undertaken between 2006 and 2018 in a tertiary referral centre was performed, including all those meeting the consensus criteria for PJI, in which organisms were identified. Using a cluster analysis, three chronological time periods were created. We then evaluated the antibiotic resistance of the identified bacteria between these three clusters and the effectiveness of our antibiotic regime. Results We identified 129 PJIs with 161 culture identified bacteria in 97 patients. Coagulase-negative staphylococci (CNS) were identified in 46.6% cultures, followed by Staphylococcus aureus in 19.8%. The overall resistance to antibiotics did not increase significantly during the study period (p = 0.454). However, CNS resistance to teicoplanin (p < 0.001), fosfomycin (p = 0.016), and tetracycline (p = 0.014) increased significantly. Vancomycin had an 84.4% overall sensitivity and 100% CNS sensitivity and was the most effective agent. Conclusion Although we were unable to show an overall increase in antibiotic resistance in organisms that cause PJI after TKA during the study period, this was not true for CNS. It is concerning that resistance of CNS to new antibiotics, but not vancomycin, has increased in a little more than a decade. Our findings suggest that referral centres should continuously monitor their bacteriological analyses, as these have significant implications for prophylactic treatment in both primary arthroplasty and revision arthroplasty for PJI.

ABSTRACT Periprosthetic joint infection (PJI) is a rare but devastating complication of total joint arthroplasty. Identifying the offending infectious agent is essential to appropriate treatment, and uncommon pathogens often lead to a diagnostic delay. This case describes the first known instance of a total knee arthroplasty (TKA) with Rothia mucilaginosa, a typical respiratory tract organism. This report aims to provide insight into the treatment of this atypical PJI, as there are only six previously published cases of Rothia species PJI septic arthritis. The patient is a 64-year-old diabetic male who underwent a right TKA and left TKA ∼6 months later. Approximately 3 weeks status post-left TKA, he showed evidence of left PJI. One year after treatment and recovery from his left PJI, he presented with several months of right knee pain and fatigue. Subsequent labs and imaging revealed right PJI. No recent history of dental disease or work was observed. He then underwent two-stage revision right knee arthroplasty and microbial cultures yielded Rothia mucilaginosa. After initial empiric treatment, antibiotic therapy was narrowed to 6 weeks of vancomycin. Following negative aspiration cultures the patient underwent reimplantation of right TKA components. One year following treatment, the patient was fully recovered with no evidence of infection. This case emphasizes the possibility of microbial persistence despite various antibiotic treatment regimens for the patient’s contralateral knee arthroplasty and PJI. Additionally, this case demonstrates the importance of two-stage revision in patients with PJI, and the viability of treating Rothia species PJIs with vancomycin.
