Meta-analysis of sonication fluid samples from prosthetic components for diagnosis of infection after total joint arthroplasty.

ABSTRACT: This meta-analysis included 12 studies that evaluated sonication fluid cultures (SFC) for the diagnosis of prosthetic joint infection (PJI). The pooled sensitivity and specificity were 0.80 (95% confidence interval [CI], 0.74 to 0.84) and 0.95 (CI, 0.90 to 0.98), respectively. Subgroup analyses showed that a 14-day anaerobic culture may improve sensitivity, the use of centrifugation or vortexing may improve specificity, and the use of 400 to 500 ml of Ringer's solution for containers may improve sensitivity and specificity. The best SFC cutoff was ?5 CFU. In conclusion, SFC has high sensitivity and very high specificity for diagnosing PJI.

Project description:BackgroundIn the absence of a gold standard criterion for diagnosing prosthetic joint infections (PJI), sonication of the removed implant may provide superior microbiological identification to synovial fluid and peri-implant tissue cultures. The aim of this retrospective study was to assess the role of sonication culture compared to tissue cultures for diagnosing PJI, using different consensus and international guidelines for PJI definition.MethodsData of 146 patients undergoing removal of hip or knee arthroplasties between 2010 and 2018 were retrospectively reviewed. The International Consensus Meeting (ICM-2018), Musculoskeletal Infection Society (MSIS), Infectious Diseases Society of America (IDSA), the European Bone and Joint Infection Society (EBJIS), and a modified clinical criterion, were used to compare the performance of microbiological tests. McNemar´s test and proportion comparison were employed to calculate p-value.ResultsOverall, 56% (82/146) were diagnosed with PJI using the clinical criteria. Out of these cases, 57% (47/82) tested positive on tissue culture and 93% (76/82) on sonication culture. Applying this clinical criterion, the sensitivity of sonication fluid and tissue cultures was 92.7% (95% CI: 87.1%- 98.3%) and 57.3% (95% CI: 46.6%-68.0%) (p<0.001), respectively. When both methods were combined for diagnosis (sonication and tissue cultures) sensitivity reached 96.3% (95% CI: 91.5%-100%). Sonication culture and the combination of sonication with tissue cultures, showed higher sensitivity rates than tissue cultures alone for all diagnostic criteria (ICM-18, MSIS, IDSA and EBJIS) applied. Conversely, tissue culture provided greater specificity than sonication culture for all the criteria assessed, except for the EBJIS criteria, in which sonication and tissue cultures specificity was 100% and 95.3% (95% CI: 87.8-100%), respectively (p = 0.024).ConclusionsIn a context where diagnostic criteria available have shortcomings and tissue cultures remain the gold standard, sonication cultures can aid PJI diagnosis, especially when diagnostic criteria are inconclusive due to some important missing data (joint puncture, histology).

Project description:Objective: The current review was designed to assess the impact of prior intra-articular injections on the risk of prosthetic joint infection (PJI) in patients undergoing total joint arthroplasty (TJA) with a focus on the timing of injection before surgery. Methods: The databases of PubMed, Embase and Google Scholar were searched up to 15th June 2021. All studies comparing the incidence of PJI with and without prior intra-articular injections were included. Risk ratios (RR) with 95% confidence intervals were calculated for PJI. Results: Nineteen studies were included. Both corticosteroids and hyaluronic acid injections were used before TJA in the included studies. Overall, comparing 127,163 patients with prior intra-articular injections and 394,104 patients without any injections, we noted a statistically significant increased risk of PJI in the injection group (RR 1.24 95% CI: 1.11, 1.38 I2 = 48% p = 0.002). On subgroup analysis, there was a statistically significant increased risk of PJI in the injection group in studies where intra-articular injections were administered <12 months before surgery (RR 1.18 95% CI: 1.10, 1.27 I2 = 7% p < 0.00001). Furthermore, on meta-analysis, we noted non-significant but increased risk of PJI when injections were administered 1 month (RR 1.47 95% CI: 0.88, 2.46 I2 = 77% p = 0.14), 0-3 months (RR 1.22 95% CI: 0.96, 1.56 I2 = 84% p = 0.11), and 3-6 months (RR 1.16 95% CI: 0.99, 1.35 I2 = 49% p = 0.06) before surgery. Conclusion: Our results indicate that patients with prior intra-articular injections have a small but statistically significant increased risk of PJI after TJA. Considering that PJI is a catastrophic complication with huge financial burden, morbidity and mortality; the clinical significance of this small risk cannot be dismissed. The question of the timing of injections and the risk of PJI still remains and can have a significant impact on the decision making. Systematic Review Registration: PROSPERO: CRD42021258297.
