Comparison between Local Infiltration Analgesia and Ultrasound Guided Single Shot Adductor Canal Block Post Total Knee Replacement Surgery - A Randomized Controlled Trial.

Context: Good quality analgesia posttotal knee arthroplasty (TKA) contributes majorly to early mobilization and shorter hospital stay.

Aim: To compare adductor canal block (ACB) versus local infiltration analgesia (LIA) for postoperative pain relief in patients undergoing TKA.

Settings And Design: This prospective, single-blind, randomized controlled trial was undertaken at a tertiary care university hospital.
