One Stage Exchange Arthroplasty: A Surgical Technique Update

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 paper, we discuss our surgical technique in undertaking a single-stage exchange of a chronic knee periprosthetic infection. Results This technique, which is based upon 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 two-staged exchange.
