Femoral Nerve Block Is Associated With Persistent Strength Deficits at 6 Months After Anterior Cruciate Ligament Reconstruction in Pediatric and Adolescent Patients

Abstract

Pediatric and adolescent patients treated with FNB for postoperative analgesia after ACL reconstruction had significant isokinetic deficits in knee extension and flexion strength at 6 months when compared with patients who did not receive a nerve block. Patients without a block were 4 times more likely to meet criteria for clearance to return to sports at 6 months.
