the value of white Blood Cell Counts before revision total knee arthroplasty
Journal of Arthroplasty, 2003Co-Authors: Bohannon J Mason, Thomas K Fehring, Susan M Odum, William L Griffin, Donna S NussmanAbstract:A white Blood Cell count (WBC) of >50,000 Cell/mm3 from a knee aspirate with ≥80% polymorphonuclear Cells (PMNCs) is suggestive of infection. This study sought to determine if these same criteria were applicable when interpreting aspirates from a total knee. Of 440 revision total knee arthroplasties, 86 patients had preoperative aspirations of the knee before revision. Fifty-five aspirates were from aseptic failures; 31 aspirates were from patients determined to have septic failure. The mean white Blood Cell (WBC) count in aspirates from the aseptic group was 645 Cells/mm3 (SD = 878). The mean WBC count in the septic group was 25,951 Cells/mm3 (SD = 34,994; P=<.001). The mean percentage of PMNCs was statistically higher in the septic group compared with the aseptic group (72.8% vs 27.3%; P=<.001). The synovial fluid WBC count differential analysis is a statistically relevant indicator of the presence or absence of infection in revision knee arthroplasty. Aspirates with a WBC count of 2,500 per milliliter and 60% PMNCs are highly suggestive of infection.

white Blood Cell Counts and differential in synovial fluid of aseptically failed total knee arthroplasty
Journal of Arthroplasty, 2000Co-Authors: Robert Kersey, James B Benjamin, Blake M MarsonAbstract:A Cell count and differential was obtained on synovial fluid samples from 79 total knee arthroplasties undergoing revision for aseptic failure over a 5-year period. The mean white Blood Cell count (WBC) was 782/mL (range, 11-7,200/mL). The mean percentage of monocyte Cells was 87%, and the mean polymorphonuclear leukocyte (PML) Cell count was 13%. Eight patients (10.4%) had leukocyte Cell Counts >2,000. Five knees in 4 patients with rheumatoid arthritis had PML Counts >50%. There was a single postoperative infection. In patients with osteoarthritis as a primary diagnosis, a synovial WBC of <2,000 and a differential with <50% PMLs had a 98% negative predictive value for the absence of infection. Key words: synovial fluid, Cell count and differential, failed total knee arthroplasty, revision total knee arthroplasty.
