Clinical Trial Summary

Opioid misuse and addiction among children and adolescents is an increasingly concerning problem. Post-surgical opioid prescriptions for commonly performed surgeries such as anterior cruciate ligament reconstruction (ACLR) increase opioid exposure in young athletes. The purpose of the current study is to determine if extended-release Bupivacaine Liposome Injectable Suspension (Exparel) is effective in decreasing at home narcotic consumption compared to standard Bupivacaine Adductor Canal Block for Anterior Cruciate Ligament (ACL) reconstruction/reconstruction for the surgical treatment of adolescents with ACL tears and concomitant pathology i.e. meniscus / cartilage injury/tear.

Clinical Trial Description

Approximately 13% of high school seniors have reported nonmedical use of prescription opioids in their lifetimes with 8.7% to 11% reporting use within the last year. The second most common source of opioids (36.9%) in this population is leftover medication from previous legitimate prescriptions after injury or procedures. Before injury or surgery, most children and adolescents are narcotic naive. Medical use of opioids in this population increases the risk for nonmedical opioid misuse after high school by 33% (1). As orthopaedic surgeons, the surgeons are in a powerful position to understand and affect change in the adolescent population through patient/parent education and through controlling the amount and type of pain medications prescribed. The investigators propose a Double Blinded RCT of adolescents with ACL +/- meniscus tear to either bupivacaine ACB or Bupivacaine Liposome Injectable Suspension ACB (Exparel) to test whether injectable suspension reduces at home narcotic consumption postoperatively. Currently there is limited data available for the pediatric population and no known randomized controlled trials. Bupivacaine Liposome Injectable Suspension is FDA approved for use in adults but has been used in this pediatric population off-label for many years. Exparel is now FDA approved and indicated for single-dose infiltration in patients aged 6 years and older to produce postsurgical local analgesia. While widely used in the settings of a regional block in adolescents undergoing ACL reconstruction and other surgeries, it does not have specific FDA approval for the use in blocks. This is not uncommon practice and in fact many of the drugs used in pediatrics do not have specific approval by the FDA(2).

After enrollment, the research subject will be randomized into one of two arms and the anesthesiologist will be notified of the arm. Data will be collected at baseline, on day of surgery, and on days 1 through 14 postoperatively. Participants will be instructed to wear Actigraphs in the days leading up to surgery to obtain baseline sleep activity data. ;
