Femoral nerve block reduces narcotic consumption and improves knee function in TKA
J Arthroplasty. 2012 Dec;27(10):1800-5. doi: 10.1016/j.arth.2012.03.052.

The trial compared systemic narcotic uses, self-reported pain, and functional outcomes at 1 year. The Knee Society score was significantly higher and the fentanyl consumption in the first 24 hours was significantly lower in the femoral nerve block group.
