    Abstract: ... joint aspiration. Correspondence: Eythor Orn Jonsson, eythororn@gmail.com. ...

    Abstract 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.
    Key words: periprosthetic joint infection, total knee replacement, quadriceps tendon rupture, hemarthrosis, joint aspiration. Correspondence: Eythor Orn Jonsson, eythororn@gmail.com.

    Abstract Background and purpose: Previous work has shown that despite preventive measures, intraoperative contamination of joint replacements is still common, although most of these patients seem to do well in follow-up of up to 5 years. We analyzed the prevalence and bacteriology of intraoperative contamination of primary joint replacement and assessed whether its presence is related to periprosthetic joint infection (PJI) on long-term follow-up.
    Patients and methods: 49 primary total hip replacements (THRs) and 41 total knee replacements (TKRs) performed between 1990 and 1991 were included in the study. 4 bacterial swabs were collected intraoperatively during each procedure. Patients were followed up for joint-related complications until March 2011.
    Results: 19 of 49 THRs and 22 of 41 TKRs had at least 1 positive culture. Coagulase-negative staphylococci and Staphylococcus aureus were the most common organisms, contaminating 28 and 9 operations respectively. Where information was available, bacteria from 27 of 29 contaminated operations were susceptible to the prophylactic antibiotic administered. 13% of samples gathered before 130 min of surgery were contaminated, as compared to 35% collected after that time. 2 infections were diagnosed, both in TKRs. 1 of them may have been related to intraoperative contamination.
    Interpretation: Intraoperative contamination was common but few infections occurred, possibly due to the effect of prophylactic antibiotics. The rate of contamination was higher with longer duration of surgery. It appears that positive results from intraoperative swabs do not predict the occurrence of PJI.
