Single-Stage Revision With Fluconazole Monotherapy in Fungal Prosthetic Knee Joint Infections

Fungal prosthetic joint infection is rare, and two-stage revision is usually advocated. We present our experience with 2 cases of fungal prosthetic knee joint infection presenting 25 months and 3 years after index surgery. Both patients were managed with single-stage revision arthroplasty and fluconazole monotherapy. They remain asymptomatic with good knee society score after 2 years of follow-up. Preoperative workup of all aseptic loosening cases should include extended culture for fungal elements. Single-stage revision with antifungal therapy for 3 months gives good results in nonimmunocompromised patients with good soft-tissue envelope.
