Patient-related risk factors for invasive Staphylococcus aureus infection overlap with those for periprosthetic joint infections (PJIs). We compared these factors and clinical characteristics between 17 exogenous and 40 haematogenous PJIs caused by S. aureus. Exogenous cases presented significantly more often with damaged periprosthetic soft tissue, whereas haematogenous cases more often had systemic signs of infection, such as fever, chills, and sepsis syndrome. However, comorbid conditions associated with S. aureus infection and/or PJIs did not differ between the two groups. These findings imply that patient-related risk factors for S. aureus infection do not help to predict the mode of infection acquisition in prosthetic joints.
与人工关节假体周围感染（PJI）相关的患者因素与金黄色葡萄球菌（S. aureus）所致的侵袭性 S. aureus 感染的患者因素重叠。我们比较了 17 例由 S. aureus 引起的外源性和 40 例血源性 PJI 之间的这些因素和临床特征。外源性病例中，假体周围软组织损伤的发生率明显更高，而血源性病例中，全身感染的症状如发热、寒战和败血症综合征更为常见。然而，与 S. aureus 感染和/或 PJI 相关的合并症在两组之间没有差异。这些发现表明，与金黄色葡萄球菌感染相关的患者因素并不能帮助预测假体关节感染的感染途径。
