IPACK Versus Popliteal Sciatic Nerve Block in ACL Reconstruction

Comparison of Postoperative Analgesic Efficacy of Adductor Canal Block With IPACK Versus Adductor Canal and Popliteal Sciatic Nerve Block in Patients Undergoing Arthroscopic Anterior Cruciate Ligament Reconstruction

This is a prospective study comparing femoral nerve block plus sciatic nerve block to femoral nerve block plus infiltration of the posterior knee capsule (IPACK) in patients undergoing arthroscopic anterior cruciate ligament reconstruction. Femoral nerve block via the adductor canal (FNB-AC) with IPACK may provide effective analgesia while avoiding the motor block involved with sciatic nerve block. The lack of motor block is important to facilitate postoperative ambulation and physical therapy.

Inclusion Criteria:

• Patients less than 21 years of age
• American Society of Anesthesiologists physical status I and II
• Undergoing elective anterior cruciate ligament reconstruction

Exclusion Criteria:

• They are unable or unwilling to take part in the study
• History of allergy to any of the medications administered for the nerve block
• Contraindication to peripheral nerve block
• Patients who are unable to understand instructions or questions related to the study or the families required language interpretation
• Patients who consume opioid medications for more than three days per week for more than a month prior to surgery
