Abstract

Insights

D-dimer shows limited diagnostic accuracy for periprosthetic joint infection (PJI). This systematic review found its performance insufficient for reliable PJI diagnosis after joint arthroplasty.

Area of Science:

  • Orthopedic Surgery
  • Diagnostic Accuracy
  • Biomarker Research

Background:

  • Periprosthetic joint infection (PJI) diagnosis is challenging.
  • D-dimer, a marker of coagulation, is being explored for PJI detection.
  • Its diagnostic reliability for PJI remains uncertain.

Purpose of the Study:

  • To systematically review and meta-analyze the accuracy of D-dimer in diagnosing PJI.
  • To assess the diagnostic performance of D-dimer in patients undergoing joint arthroplasty.

Main Methods:

  • Systematic search of MEDLINE, EMBASE, and Cochrane databases.
  • Quality assessment using QUADAS-2.
  • Bivariate meta-analysis to pool sensitivity, specificity, PLR, NLR, DOR, and AUC.
  • Meta-regression and subgroup analyses to explore heterogeneity.

Main Results:

  • Included 8 studies.
  • Pooled sensitivity: 0.82 (95% CI, 0.70-0.89).
  • Pooled specificity: 0.70 (95% CI, 0.55-0.82).
  • Area under the SROC curve (AUC): 0.83 (95% CI, 0.8-0.86).
  • Serum D-dimer showed potentially higher accuracy than plasma D-dimer.

Conclusions:

  • D-dimer demonstrates limited performance in diagnosing PJI.
  • Current evidence suggests insufficient reliability for routine PJI diagnosis.
