This meta-analysis evaluated preoperative aspiration culture for diagnosing prosthetic joint infection (PJI) in total hip arthroplasty (THA) and total knee arthroplasty (TKA). The pooled sensitivity and specificity were 0.72 (95% confidence interval, 0.65 to 0.78) and 0.95 (0.93 to 0.97), respectively. Subgroup analyses revealed nonsignificant worse diagnostic performance for THA than for TKA (sensitivity, 0.70 versus 0.78; specificity, 0.94 versus 0.96). Preoperative aspiration culture has moderate to high sensitivity and very high specificity for diagnosing PJI.
这项荟萃分析评估了术前抽吸培养在全髋关节置换术 (THA) 和全膝关节置换术 (TKA) 中诊断人工关节感染 (PJI) 的作用。汇总的敏感性和特异性分别为 0.72(95%置信区间,0.65 至 0.78)和 0.95(0.93 至 0.97)。亚组分析显示,THA 的诊断性能略逊于 TKA(敏感性,0.70 对 0.78;特异性,0.94 对 0.96)。术前抽吸培养对诊断 PJI 具有中等到高度的敏感性和非常高的特异性。
