The incidence of deep fungal infection due to non-albicans Candida species (especially Candida glabrata) has significantly increased in recent decades. Candida glabrata is an opportunistic pathogen of low virulence which mainly invades the gastrointestinal, genitourinary, and respiratory tracts, but has rarely been reported as complication of articular surgery in the literature. We present a case of knee fungal arthritis caused by C. glabrata after a minimally invasive arthroscopic surgery. In this case, the patient's knee got infected after arthroscopic treatment for a recurrent popliteal cyst, and she was unable to be cured by either debridement or antifungal drugs. Mycological and molecular identification of the necrotic tissues isolate revealed C. glabrata as etiologic agent. We originally planned to conduct a debridement once again, but it was found that the articular cartilage was extensively damaged during the operation. Besides, the magnetic resonance imaging of the affected knee also showed that the infection had invaded the subchondral bone. So we treated this case with a two-stage primary total knee arthroplasty with an antibiotic-laden cement spacer block. After a 10-month follow-up, the patient had completely recovered and has not experienced any recurrence to date. In addition, we review 21 cases of C. glabrata-induced infectious arthritis described to date in the literature.
