Infected prosthetic knee replacement: What to do and what not to do

This article is an expansion of a lecture given in the British Orthopaedic Association (BOA) Congress in Liverpool in 2019 as part of a symposium on infected knee replacement. It is designed to provide pointers and advice to surgeons on how these patients can be referred, investigated, and managed. The management of periprosthetic infection necessitates many decisions to be made to provide the patient with the best advice and treatment. This is a discussion of the philosophies of periprosthetic knee infection. It is not a definitive guide nor a metanalysis of scientific papers. These are the subjective views of the author and generalise decision making. All decisions should remain tailored to the patient's needs.
