A subgroup analysis of the 57 patients diagnosed with septic arthritis with or without concurrent osteomyelitis once again revealed no differences between patients with and without preoperative MRI regarding age (p = 0.72), gender (p = 0.46), duration of symptoms (p = 0.71), temperature (p = 0.27), ESR (p = 0.57), CRP (p = 0.85), WBC (p = 0.58), and positive blood culture (p = 0.77), as seen in Table 3. The gene discussed is CRP; the disease is bacterial arthritis.
