Aspergillus infection after total knee arthroplasty

The literature includes little information about the treatment protocol for Aspergillus infection after total knee arthroplasty. In this article, we describe the case of a nonimmunocompromised patient who lacked predisposing risk factors and who initially presented with aseptic loosening of a total knee prosthesis that postoperatively had grown Aspergillus niger. Intraoperative culture and frozen-section results for the pseudocapsule were negative. Two days postoperatively, culture results showed heavy growth of A niger. The patient was treated with a 6-week course of amphotericin B followed by oral antifungal therapy. She was doing well and had no symptoms 12 months after surgery.
