What this trial studies

This clinical trial aims to evaluate the effectiveness of extended-release Bupivacaine Liposome Injectable Suspension (Exparel) compared to standard Bupivacaine Adductor Canal Block in reducing postoperative narcotic consumption in adolescents undergoing anterior cruciate ligament (ACL) reconstruction. The study will involve a double-blinded randomized controlled trial design, enrolling patients aged 7-17 years who are scheduled for elective ACL surgery. The goal is to address the rising concern of opioid misuse among young athletes by potentially minimizing their exposure to narcotics post-surgery.

Who should consider this trial

Good fit: Ideal candidates are adolescents aged 7-17 years undergoing elective ACL reconstruction with ASA Classification 1-2.

Not a fit: Patients with prior major surgeries or those with learning disabilities or developmental delays may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could significantly reduce opioid consumption in adolescents after ACL surgery, thereby lowering the risk of opioid misuse.

How similar studies have performed: While there is limited data available for the pediatric population, the use of Bupivacaine Liposome Injectable Suspension has been FDA approved for adults, indicating potential for success in similar applications.
