Comparison of the Analgesic Effect of Subsartorial Saphenous Block and Popliteal Sciatic vs Subsartorial Saphenous Block and IPACK in Total Knee Replacement Surgery. A Double Blind Randomized Clinical Trial.

What this Trial Is About

Researchers are comparing two types of nerve blocks to manage pain and preserve motor function after total knee replacement surgery. The study focuses on patients with osteoarthritis undergoing this surgery, aiming to evaluate the effectiveness of the subsartorial saphenous block combined with either a sciatic nerve block or an iPACK block. The goal is to understand how these approaches affect pain relief and limb movement post-surgery. Participants receive either an iPACK block or a sciatic nerve block, both using 0.25% bupivacaine with adrenaline, administered once during surgery. The iPACK block targets nerve branches near the back of the knee, while the sciatic block involves a different nerve area. This is a double-blind, randomized trial comparing these two methods to see which provides better pain control and motor function. Participants will be monitored for pain levels at rest and during movement at 6, 24, and 48 hours after surgery, along with assessments of motor block at the same times. Additional measures include opioid use, patient satisfaction, discharge timing, and the ability to walk within 24 hours. The study involves follow-up during the immediate postoperative period to assess these outcomes and support early rehabilitation.
