Imaging the pediatric anterior cruciate ligament: not little adults

Area of Science:

• Pediatric Orthopedics
• Musculoskeletal Imaging
• Sports Medicine

Background:

• Increasing incidence of anterior cruciate ligament (ACL) injuries in pediatric populations.
• Corresponding rise in ACL reconstruction procedures for children.
• Need for specialized imaging interpretation in pediatric ACL cases.

Purpose of the Study:

• To illustrate unique imaging features of the ACL in children compared to adults.
• To review imaging findings of congenital ACL dysplasia.
• To discuss imaging of ACL avulsions and post-operative appearances of pediatric ACL reconstructions.

Main Methods:

• Review of normal anterior cruciate ligament (ACL) anatomy in children.
• Analysis of imaging findings associated with congenital ACL dysplasia.
• Evaluation of imaging characteristics of ACL avulsions in pediatric patients.
• Assessment of imaging post-anterior cruciate ligament (ACL) reconstruction in skeletally immature individuals.

Main Results:

• Unique imaging characteristics differentiate pediatric ACL anatomy and pathology from adults.
• Congenital ACL dysplasia presents specific imaging findings.
• ACL avulsions in children have distinct imaging appearances.
• Various ACL reconstruction techniques in skeletally immature patients yield characteristic post-operative imaging.

Conclusions:

• Understanding unique pediatric ACL imaging is crucial for accurate diagnosis.
• Imaging plays a vital role in evaluating congenital anomalies, acute injuries, and post-operative outcomes in pediatric ACL reconstructions.
• Specialized knowledge of pediatric ACL imaging aids in appropriate management and surgical planning.
