Femoral nerve blockade as a preemptive anesthetic in patients undergoing anterior cruciate ligament reconstruction: A prospective, randomized, double-blinded, placebo-controlled study

This report has been verified by one or more authors of the original publication.

56 patients undergoing endoscopic patellar tendon anterior cruciate ligament (ACL) reconstruction were recruited to this double blind trial. Patients were randomized to receive additional analgesic treatment using either a femoral nerve block (FNB) or a saline injection, in combination with local anesthesia. The results from this trial indicated that the FNB did not provide reduction in pain scores at any time point in comparison to the placebo. This treatment also failed to reduce medication consumption in these groups.
