Infiltration or Nerve Blocks in Addition to Adductor Canal Block

In addition to the adductor canal block, this quadruple block incorporates : 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.
