Abstract
BACKGROUND: Standard surgical treatment for a periprosthetic knee infection has been based on a staged surgical technique, in order to assure infection eradication prior to implantation of a new prosthesis. METHODS: In this article, we discuss our surgical technique in undertaking a single-stage exchange of a chronic knee periprosthetic infection. RESULTS: This technique, which is based on the fundamental principles of controlling infection, preventing recurrence, and restoring function, has been shown to deliver high success rates. CONCLUSION: As demonstrated, when undertaken under appropriate circumstances, a single-stage exchange combined with local and systemic antibiotic delivery can result in infection eradication comparable to a 2-staged exchange.
