Summary

Total knee arthroplasty (TKA) often results in significant postoperative pain, which can hinder recovery despite advances in surgical and anesthetic techniques. Traditional pain management methods like femoral nerve blocks may impair motor function, delaying rehabilitation. The iPACK block, targeting the posterior knee without affecting motor control, offers a promising alternative. This study aims to compare the effectiveness of two iPACK block approaches-proximal (at the distal femoral shaft) and distal (between the femoral condyles)-in managing postoperative pain in TKA patients. In a double-blind, randomized controlled trial with 120 participants, pain scores, opioid use, and time to rescue analgesia will be assessed. The hypothesis is that the distal iPACK block provides superior pain relief, potentially improving patient outcomes and recovery.

Conditions

  • Postoperative Pain Following Knee Arthroplasty

Interventions

PROCEDURE

distal iPACK

● In the distal iPACK group, participants will receive 20 ml of 0.25% levobupivacaine with adrenaline (1:200,000), injected at the most distal part of the thigh, between the femoral condyles.

PROCEDURE

proximal iPACK

● In the proximal iPACK group, participants will receive 20 ml of 0.25% levobupivacaine with adrenaline (1:200,000), injected at the level of the distal femoral shaft (a straight portion of the femur without the condyles).
