Brief Summary
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.

Outcome Measures
Primary Outcomes (9)
Pain at rest
Measured by the numerical visual scale at 6 hours after intradural anesthesia, minimum of 0 and maximum of 10, where means no pain and 10 means the worst pain in the life of the patient.
6 hours after surgery
Pain at rest
Measured by the numerical visual scale at 24 hours after intradural anesthesia, minimum of 0 and maximum of 10, where means no pain and 10 means the worst pain in the life of the patient.
24 hours after surgery
Pain at rest
Measured by the numerical visual scale at 48 hours after intradural anesthesia, minimum of 0 and maximum of 10, where means no pain and 10 means the worst pain in the life of the patient.
48 hours after surgery
Pain at movement
Measured by the numerical visual scale at 48 hours after intradural anesthesia, minimum of 0 and maximum of 10, where means no pain and 10 means the worst pain in the life of the patient.
6 hours after surgery
Pain with movement
Measured by the numerical visual scale at 48 hours after intradural anesthesia, minimum of 0 and maximum of 10, where means no pain and 10 means the worst pain in the life of the patient.
24 hours after surgery
Pain with movement
Measured by the numerical visual scale at 48 hours after intradural anesthesia, minimum of 0 and maximum of 10, where means no pain and 10 means the worst pain in the life of the patient.
48 hours after surgery
Motor block
Measured on a scale of 3, where 0 = no motor block, 1 = partial motor block and 2 = complete motor block. It will be performed on plantar flexion (distribution of the tibial nerve) and dorsiflexion (peroneal distribution)).
6 hours after surgery
Motor block
Measured on a scale of 3, where 0 = no motor block, 1 = partial motor block and 2 = complete motor block. It will be performed on plantar flexion (distribution of the tibial nerve) and dorsiflexion (peroneal distribution)).
24 hours after surgery
Motor block
Measured on a scale of 3, where 0 = no motor block, 1 = partial motor block and 2 = complete motor block. It will be performed on plantar flexion (distribution of the tibial nerve) and dorsiflexion (peroneal distribution)).

Study Arms (2)
Echo-guided IPACK block
EXPERIMENTALIPACK block using 0.25% bupivacaine 15mL with adrenaline once.
Echo-guided sciatic block
ACTIVE COMPARATORSciatic nerve block using 0.25% bupivacaine 15mL with adrenaline once.
Interventions
The iPACK in performed in the popliteal fossa about 1 finger breath above the patella, ecoguided. That aims to anesthetize the articular branches to the posterior aspect of the knee in the popliteal region.
