Background:
Periprosthetic joint infection (PJI) is the most serious complication following total joint arthroplasty (TJA) and has a significant impact on patients and the national healthcare system. To date, the diagnosis of PJI is still confronted with dilemmas. The present study investigated the validity of sonication fluid culture (SFC) for removing implants in the diagnosis of PJI after joint replacement.
Methods:
From database establishment to December 2020, relevant literature was retrieved from the PubMed, Web of Science, Embase and Cochrane Library databases. Two reviewers independently performed quality assessment and data extraction to calculate the pooled sensitivity, specificity, positive likelihood ratio (PLR), negative likelihood ratio (NLR), area under the curve (AUC) and diagnostic odds ratio (DOR) to evaluate the diagnostic value of overall SFC for PJI.
Results:
A total of 38 eligible studies including 6302 patients were selected in this study. The pooled sensitivity, specificity, PLR, NLR, and DOR of SFC for PJI diagnosis were 0.77 (95% confidence interval [CI], 0.76-0.79), 0.96 (95% CI, 0.95-0.96), 18.68 (95% CI, 11.92-29.28), 0.24 (95% CI, 0.21-0.29), and 85.65 (95% CI, 56.46-129.94), respectively, while the AUC was 0.92.
Conclusion:
This meta-analysis showed that SFC was of great value in PJI diagnosis, and the evidence of SFC on PJI was more favorable but not yet strong. Therefore, improvement of the diagnostic accuracy of SFC is still necessary, and the diagnosis of PJI continues to warrant a multiplex approach before and during a revision procedure.
Insights
Sonication fluid culture (SFC) shows significant value in diagnosing periprosthetic joint infection (PJI) after joint replacement. While promising, further improvements are needed for optimal diagnostic accuracy in PJI cases.
Area of Science:
- Orthopedics
- Infectious Diseases
- Diagnostic Microbiology
Background:
- Periprosthetic joint infection (PJI) is a severe complication of total joint arthroplasty (TJA).
- Accurate diagnosis of PJI remains challenging, impacting patient outcomes and healthcare costs.
- Investigating the utility of sonication fluid culture (SFC) for PJI diagnosis is crucial.
Approach:
- A systematic review and meta-analysis of relevant literature was conducted.
- Data from 38 studies involving 6302 patients were analyzed.
- Pooled sensitivity, specificity, and AUC were calculated to evaluate SFC's diagnostic performance.
Key Points:
- SFC demonstrated a pooled sensitivity of 0.77 and specificity of 0.96 for PJI diagnosis.
- The area under the curve (AUC) for SFC was 0.92, indicating strong diagnostic capability.
- Positive and negative likelihood ratios suggest SFC is a valuable diagnostic tool.
Conclusions:
- Sonication fluid culture (SFC) is a valuable tool for diagnosing periprosthetic joint infection (PJI).
- While SFC shows favorable evidence, its diagnostic accuracy requires further enhancement.
- A multiplex diagnostic approach remains essential for PJI diagnosis, especially during revision procedures.

Sputum culture and sensitivity is a medical procedure used to diagnose bacterial infections in the respiratory tract and select the most appropriate antibiotics for treatment. This process involves analyzing sputum samples of thick and opaque secretions produced in the lungs and airways. These samples are collected from patients and then sent to the laboratory for analysis.
The test can identify various pathogens responsible for respiratory infections, including Streptococcus,...
