Nerve blocks for pain after knee replacement: two methods compared
Part of Bones, joints & muscles, Pain clinical trials.
This study compares two ways to manage pain after total knee replacement, using nerve blocks (injections that numb the nerves). One method combines a block near the upper thigh with a block behind the knee; the other combines the same upper-thigh block with a different block around the knee. The goal is to see which provides better pain relief and helps you recover more comfortably.

This trial tests adding an extra nerve block (IPACK) to the usual adductor canal block to see if it improves pain, recovery, and inflammation after total knee replacement surgery.
This trial tests two types of nerve blocks (numbing injections around the knee) to see which works best for pain control after knee replacement surgery. Both approaches use the same anesthesia method, and researchers want to learn if adding an extra nerve block helps reduce pain and improve recovery.
This trial tests if adding extra nerve blocks (sciatic, BiFeS, or IPACK) to the usual adductor canal block can reduce pain after total knee replacement. The goal is to find a better way to manage pain and improve recovery.
This trial tests two types of nerve blocks—iPACK and BiFeS—to see if they help people feel better and recover faster after total knee replacement surgery. It compares adding these blocks to the usual spinal anesthesia.
This study compares two different nerve-blocking anesthesia techniques to see which one controls pain better after knee replacement surgery. Both methods are designed to numb the area around your knee so you need less pain medication afterward.
This trial compares two ways of giving a nerve block for pain relief during and after double knee replacement surgery. It aims to find which method works better.
