  • In children with new development of joint pain, two major diagnoses to consider are septic arthritis and transient synovitis
  • Our patientโ€™s presentation more consistent with septic arthritis due to fever and refusal to bear weight, and therefore patient requires immediate drainage of joint space even before administering antibiotics because of risk for persistent damage to joint
