Analgesic Efficacy of Genicular Nerve Block Versus (IPack Block ) in Patients Undergoing (ACL) Repair

Analgesic Efficacy of Genicular Nerve Block Versus Local Anaesthetic Infiltration Between Popliteal Artery and Capsule of the Knee (IPACK Block ) in Patients Undergoing Anterior Cruciate Ligament (ACL) Repair by Knee Arthroscopy . A Randomized Controlled Prospective Study .

One of the most common injuries to the knee is an anterior cruciate ligament (ACL) sprain or tear due to trauma ACL damage is crippling and often requires repair with an arthroscopic method, which is an outpatient surgery. Nevertheless, patients experience severe postoperative pain on the first day after the ACL reconstruction.Efficient postsurgery pain management is an important part of patient recovery that is also crucial for their satisfaction.

The optimum role of peripheral nerve blocks in ACL reconstruction continue to be debated as a component of multi-modal analgesia . As such ,an ideal block for ACLR would target sensation but not motor function,have minimal complication risk,and be easily reproducible The genicular nerves include branches from the femoral, common peroneal, saphenous, tibial, and obturator nerves which innervate the knee capsule . The superolateral, superomedial, and inferomedial On the other hand, the interspace between the Popliteal Artery and Capsule of the Knee (IPACK) block provides analgesia on the posterior knee joint, and the application of a genicular or IPACK block has been be associated with promising outcomes following the ACLR surgery
