Lab Studies:
WBC 4500/µL, ESR 34 mm/hr, CRP of 2.4 mg/dL. Joint aspiration yielded 120 mL of a cloudy yellow fluid with 24,200 nucleated cells/mm3 with 89% neutrophils, 2000 RBCs/mm3, no crystals, and a negative culture.
Other Studies:
Knee radiographs showed a large joint effusion, normal joint spaces and bones and otherwise negative. Knee MRI showed a moderate-to-large joint effusion with frond-like fatty tissue in the anterolateral knee; synovial proliferation or scarring; and intact menisci, ligaments, and tendons <a href="CaseStudyImages/CS1Acuteatraumatickn-863.jpg" title="Case Photo #1" data-lity><b>Case Photo #1</b></a> <a href="CaseStudyImages/CS2Acuteatraumatickn-863.jpg" title="Case Photo #2" data-lity><b>Case Photo #2</b></a> .
