Prospective Femoral Versus Femoral and Sciatic Nerve Block for Anterior Cruciate Ligament (ACL) Reconstruction

Not Applicable

Completed

• Conditions: Anterior Cruciate Ligament Tear
• Interventions: Procedure: Sciatic Block; Procedure: Femoral Block only

• Registration Number: NCT01447277
• Lead Sponsor: University of California, San Francisco

Brief Summary

The investigators propose that a preoperative femoral and sciatic blocks vs a femoral block only, prior to ambulatory anterior cruciate ligament (ACL) reconstruction will lead to a decrease in opiate consumption, pain scores, and post-anesthesia care unit (PACU) length of stay. The investigators are prospectively randomizing patients to either a femoral or a fem/sciatic block and monitor outcomes.

Detailed Description

Although femoral nerve blocks improve analgesia after anterior cruciate ligament (ACL) reconstruction, patients often complain of posterior knee pain, which can be treated with a sciatic nerve block. In a prospective randomized study, we compare preoperative femoral nerve block to a combined femoral and sciatic block in patients undergoing ambulatory ACL reconstruction. We hypothesize that the combined femoral/sciatic nerve block patients would have improved analgesia, fewer opioid-related side effects, and shorter PACU length of stay and improved patient satisfaction.
