A 65-year-old male with a medical history of diabetes mellitus, chronic kidney failure, and ulcerative colitis arrived at our facility with knee monoarthritis. The knee was tapped with 40 cc pus-like discharge [Figure 1A]. He was referred for a knee lavage with a working diagnosis of septic arthritis. The patient was afebrile, denied trauma, without neutrophilia on blood count.
