It is unknown whether intraoperative subcutaneous wound closing culture samples (WCCS) are useful to predict periprosthetic joint infection (PJI).
Here we prospectively followed 167 out of a total of 175 consecutive patients with primary total hip (THR) or knee replacement (TKR) between 01/2002 and 12/2002 for a mean follow-up period of 5 years; of those patients, n = 159 (96.8%) underwent WCCS.
The results showed a positive WCCS in n = 9 cases (5.8%). Nine patients developed postoperative wound complication and required revision surgery. Two patients developed signs of a deep periprosthetic infection; however, only one out of nine patients had initial positive WCCS.
Our results thus indicate that WCCS during primary joint replacement is not an appropriate predictive method to identify patients at risk for periprosthetic joint infections.
目前尚不清楚术中皮下创口闭合培养样本（WCCS）是否有助于预测假体周围关节感染（PJI）。
我们前瞻性地随访了 2002 年 1 月至 2002 年 12 月期间总共 175 例初次全髋关节置换术（THR）或全膝关节置换术（TKR）患者中的 167 例，平均随访时间为 5 年；其中，n = 159（96.8%）例患者接受了 WCCS。
结果显示，n = 9 例（5.8%）患者的 WCCS 呈阳性。9 例患者发生术后伤口并发症并需要翻修手术。2 例患者出现深部假体周围感染的迹象；然而，9 例患者中只有 1 例最初的 WCCS 呈阳性。
因此，我们的研究结果表明，初次关节置换术中的 WCCS 不是一种识别假体周围关节感染风险患者的合适预测方法。
