Anterior Cruciate Ligament Pain Study

This trial is a prospective, randomized, surgeon-blinded, two-armed trial to investigate the
safety and efficacy of femoral nerve blocks versus adductor canal blocks versus no block for
participants undergoing outpatient anterior cruciate ligament (ACL) reconstruction surgery.

The objective of this study is to compare the pain control benefit of two different types of
nerve blocks. Ropivacaine, which is FDA-approved for use in both femoral nerve blocks as
well as adductor canal blocks, will be utilized. The study will be comparing the efficacy
between FDA approved treatments.
