Official Title

Adductor Canal Block With Liposomal Bupivacaine (Exparel) Versus Femoral Nerve Catheter for Anterior Cruciate Ligament Reconstruction: A Prospective Randomized Trial

Brief Summary

      Liposomal bupivacaine injectable suspension (Exparel), manufactured by Pacira
      Pharmaceuticals, is an FDA-approved, long-lasting nonopioid analgesic that is indicated for
      single-dose infiltration in adults to produce postsurgical local analgesia. Exparel's
      extended bioavailability allows for 48 hours of pain control. Periarticular infiltration of
      liposomal bupivacaine has been safely and effectively used for total knee arthroplasty as an
      alternative to FNBs, avoiding transient quadriceps weakness and potential in-hospital falls.
      Recently Exparel has been FDA approved for interscalene brachial plexus nerve block to
      produce postsurgical regional analgesia for upper extremity/shoulder procedures. It is not
      yet approved for peripheral nerve blocks of the lower extremity.

      No study to date, to our knowledge, has evaluated the efficacy of single-dose adductor canal
      blockade with Exparel compared to femoral nerve catheter with bupivacaine. We pose that
      Exparel used for an adductor canal block can offer the benefit of a single-dose injection
      with extended pain control without the burden of an indwelling catheter and to avoid adverse
      events of femoral nerve blockade related to quadriceps weakness and dysesthesias.

      The purpose of this study is to determine whether adductor canal blockade with liposomal
      bupivacaine (Exparel) is a safe and effective alternative to femoral nerve catheters for
      post-operative pain control for patients undergoing ACL reconstruction.
