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

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT01447277
Recruitment Status : Completed

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.

Condition or disease Intervention/treatment Phase
Anterior Cruciate Ligament Tear Procedure: Sciatic Block Procedure: Femoral Block only Not Applicable

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.
