Subjects and Methods: A cross-sectional descriptive study was conducted on 70 patients with chronic knee effusion treated at Thai Nguyen National Hospital. Results: The most common cause of chronic knee effusion is osteoarthritis (38.6%). Results of leukocyte formula in synovial fluid: average white blood cell count: 20941±29436 cells/ml, of which 45.7% of synovial fluid samples had white blood cell levels from 2000 to 50000 cells/ml, 37.1% of fluid samples had white blood cell levels <
2000 cells/ml
the levels >
50,000 cells/ml accounts for 17.2%. The average proportion of polymorphonuclear neutrophils is 63.3±25%, synovial fluid samples had the proportion of polymorphonuclear neutrophils levels from 50% to 90% accounting for 51.4%. Synovial fluid stain: 2.9% of synovial fluid samples were positive for Gram-positive cocci, 87.1% of synovial fluid samples had negative results. Synovial fluid culture: 10% of patients had positive results. Among the causes of knee infection, Staphylococcus aureus accounts for 85.7%, the remaining is Pseudomonas aeruginosa (14.3%). Conclusion: Synovial fluid white blood cells count varies greatly between patients (average: 20941±29436 cells/ml). The proportion of synovial fluid samples with positive staining and culture results is low. Knee joint effusion due to infection is commonly caused by Staphylococcus aureus.
