Insights

Point-of-care ultrasound (POCUS) effectively diagnosed traumatic knee arthrotomy in two pediatric patients with penetrating knee injuries. This imaging method proved low-risk and efficient for identifying trapped air in the knee joint.

Area of Science:

  • Pediatric Orthopedics
  • Emergency Medicine
  • Diagnostic Imaging

Background:

  • Traumatic knee injuries in children can lead to arthrotomy, requiring prompt diagnosis.
  • Limited data exists on the utility of point-of-care ultrasound (POCUS) for pediatric traumatic knee arthrotomy.
  • POCUS is recognized as a safe and efficient imaging modality for various conditions.

Purpose of the Study:

  • To evaluate the effectiveness of POCUS in diagnosing traumatic knee arthrotomy in pediatric patients.
  • To highlight POCUS as a potential diagnostic tool in the pediatric emergency setting for knee injuries.

Main Methods:

  • Case report of two pediatric patients with penetrating knee trauma.
  • Point-of-care ultrasound (POCUS) was performed to assess knee joint pathology.
  • Further imaging and surgical evaluation (irrigation and debridement) were conducted.

Main Results:

  • POCUS revealed trapped air in the suprapatellar bursa in both cases, consistent with arthrotomy.
  • The diagnosis was confirmed, leading to urgent surgical intervention.
  • POCUS provided rapid and accurate diagnostic information.

Conclusions:

  • POCUS is a valuable, low-risk, and efficient tool for diagnosing traumatic knee arthrotomy in pediatric emergency departments.
  • This case series supports the expanded use of POCUS in pediatric orthopedic emergencies.
  • Further research is warranted to establish POCUS protocols for traumatic knee injuries in children.
