Pain Control for Anterior Cruciate Ligament Reconstruction Patients With Adductor Canal or Femoral Perineural Infusions

July 21, 2023 updated by: Jean-Louis Horn, Stanford University

A Prospective Comparison of Pain and Quality of Recovery in Patients Undergoing Anterior Cruciate Ligament Reconstruction With Adductor Canal or Femoral Perineural Infusions

Nerve blocks are used to provide pain control after moderately painful orthopedic surgeries. Anterior Cruciate Ligament (ACL) reconstruction with patellar autograft is a painful orthopedic procedure performed after traumatic injury to the knee. Many patients undergoing ACL reconstruction receive a nerve block as part of their anesthetic care. These blocks can be performed in different locations along the femoral nerve, with advantages and disadvantages to each location. Recently published evidence indicates that there is no short-term difference in pain control between the two commonly-targeted locations ("Adductor Canal" and "Femoral"). However, studies involving patients undergoing total knee arthroplasty indicate that femoral blocks provide better pain control with movement than adductor canal blocks. As many patients undergoing ACL reconstruction use continuous passive motion (CPM) machines as part of rehabilitation starting on post-operative day one, the investigators hypothesize that pain control and quality of recovery in the first 48 hours after surgery will be superior with a continuous femoral block than with a continuous adductor canal block. The investigators plan to study this by randomizing patients presenting for ACL reconstruction to receive either a continuous femoral or continuous adductor canal block (both considered adequate means of pain control), and following them to 48 hours to determine the level of pain, quality of recovery score, opioid use, and CPM compliance.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.
