Comparison of the Analgesic Effect of Subsartorial Saphenous Block and Popliteal Sciatic vs Subsartorial Saphenous Block and IPACK in Total Knee Replacement Surgery.

Total knee replacement surgery is associated with significant pain in the immediate postoperative period, especially in movement. In turn, this is associated with more subsequent chronic pain. There are multiple options and the tendency is to perform increasingly distal nerve blocks to minimize limb weakness and thus allow early rehabilitation. In 2012, in an oral communication, Sanjay Sinha described a new nerve block called iPACK ("Interspace between the Popliteal Artery and the Capsule of the posterior Knee"). There are few studies on the efficacy of such a blockade so far, but none comparing the groups saphene + sciatic blocks vs. saphene + iPACK blocks. Therefore, this study aims to provide more information on the effectiveness this nerve blocks, in total knee replacement, in terms of analgesia and motor function.
