Answer

If the patient's condition does not improve significantly after 5 days, the joint must be reaspirated and examined. Most septic joints have a white blood cell (WBC) count that exceeds 50,000/μL, with more than 75% polymorphonuclear leukocytes. However, various sterile inflammatory processes may exhibit the same cellular profile.
