Femoral Nerve Block versus Intra-Articular Infiltration: A Preliminary Study of Analgesic Effects and Quadriceps Strength in Patients Undergoing Arthroscopic Anterior Cruciate Ligament Reconstruction.

Background: Adequate analgesia and early rehabilitation is necessary for arthroscopic anterior cruciate ligament reconstruction (A CLR) surgery.

Objective: To compare analgesia and quadriceps strength after femoral nerve block (FNB) with intra-articular infiltration (IA) using 0.25% bupivacaine for ACLR with patella tendon graft.
