An 80-year old male presented with an infected knee replacement following repeated joint aspirations. They were carried out due to recurrent hemarthrosis resulting from an initially missed quadriceps tendon injury. The infection was eradicated first after arthrodesis. This case highlights that prosthetic joints are sensitive to infection, which once established can be difficult to eradicate. Careful consideration is necessary before aspirating prosthetic joints. Diagnosing quadriceps tendon injuries can be difficult and they must be included in the differential diagnosis of traumatic hemarthrosis. We review the initials steps in the diagnosis and management of periprosthetic joint infections.

一名80岁男性在多次关节穿刺后出现感染性膝关节置换。这些穿刺是由于最初漏诊的股四头肌肌腱损伤导致反复关节积血而进行的。在关节融合术后首先根除了感染。该病例强调了人工关节对感染敏感，一旦感染确立就难以根除。在对人工关节进行穿刺之前必须仔细考虑。诊断股四头肌肌腱损伤可能很困难，并且它们必须包含在创伤性关节积血的鉴别诊断中。我们回顾了人工关节周围感染诊断和管理的初步步骤。
