Dynamic Intraligamentary Stabilization (DIS) Repair for ACL Ruptures in Pediatric and Adolescent Patients: An Initial...

Area of Science:

• Orthopedic Surgery
• Pediatric Sports Medicine
• Biomechanical Engineering

Background:

• Anterior cruciate ligament (ACL) ruptures are common in pediatric and adolescent athletes.
• Skeletally immature patients present unique challenges for ACL injury management.
• Dynamic intraligamentary stabilization (DIS) is an emerging technique for ACL repair.

Purpose of the Study:

• To report initial experiences with the DIS technique for ACL ruptures in children and adolescents.
• To evaluate the short-term and long-term outcomes of DIS in this patient population.
• To assess functional recovery, stability, and reintervention rates following DIS.

Main Methods:

• A case series of 22 pediatric patients with ACL ruptures treated with DIS.
• Off-label use of the DIS technique in skeletally immature individuals.
• Comprehensive evaluations including laxity, strength, range of motion, and functional scores (Tegner, Lysholm, IKDC, PedsQL) at 3 and 11 years post-surgery.

Main Results:

• No significant differences in laxity, strength, or range of motion between injured and contralateral knees at 3 years.
• A slight decrease in Tegner Index score from 7.1 to 6.3.
• High overall failure rate of 55%, with 10 reruptures and 2 revision reconstructions by 11 years.

Conclusions:

• The DIS technique may facilitate ACL healing and provide satisfactory short-term functional outcomes.
• The high failure and reintervention rates necessitate further research to establish non-inferiority in pediatric patients.
• DIS is not yet considered a standard treatment option for pediatric ACL ruptures due to concerns about long-term efficacy.
