UNLABELLED: 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.
