Outcome of single-stage versus two-stage exchange for revision knee arthroplasty for chronic periprosthetic infection

[摘要] Prosthetic joint infection (PJI) remains one of the most serious complications of knee prosthesis implantation. Its incidence is reported as between 0.5% and 2.0% according to the risk factors.1–4 It is the commonest reason for total knee arthroplasty (TKA) revision in the United States.5 Of these revisions, 25% are due to infectious disease and the cost per case is 50,000 US dollars.4–7 Today there are now two options for the treatment of delayed PJI around the knee: single- and two-stage revision arthroplasty.
