Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
1. the block of the lateral cutaneous nerve of the thigh (or femoral-cutaneous nerve), which is a collateral sensory branch of the posterior part of the lumbar plexus.
2. IPACK (Infiltration between Popliteal Artery and Capsule of Knee), designed as a motor-sparing technique (targeting the sensory articular branches of the sciatic nerve and avoiding the motor branches of the tibial and fibular nerves), is particularly effective on posterior pain.
3. obturator nerve block, a mixed nerve originating from the anterior part of the lumbar plexus. It divides into two branches: anterior, which innervates the adductor longus, adductor brevis and gracilis muscles, and posterior, which innervates the medial part of the knee joint and the posteromedial part of the thigh. It provides sensitivity to the medial aspect of the thigh.

RANDOMIZED
PARALLEL
Multi-center (2 sites), prospective, double-blind randomized, open-label study of two parallel groups of patients undergoing total knee arthroplasty according to locoregional analgesia (LRA) protocol :
* Group 1: Real adductor canal block + surgical infiltration and sham of femoro-cutaneous block + obturator block + IPACK block with physiological serum
* Group 2: Real adductor canal block + femoro-cutaneous block + obturator block + IPACK block and sham of surgical infiltration with physiological serum
