Comparing two ways to give a knee nerve block for pain after knee replacement
Part of Pain clinical trials.
This study compares two different ways of giving a nerve block (called iPACK) to see which works better for pain after total knee replacement. The goal is to find the best spot for the injection to help you feel more comfortable after surgery.
Summary written for real people, not researchers, by Clin2.

This study compares two ways to manage pain after a total knee replacement: a nerve block (iPACK) versus injecting pain medicine around the knee. The goal is to find which method provides better pain relief with fewer side effects.
This trial compares two different nerve blocks to see which one controls pain better after knee replacement surgery. Both are given along with a continuous pain pump, and the goal is to improve recovery with fewer side effects.
This study compares two ways of numbing the knee after replacement surgery. One uses a continuous nerve block in the thigh, and the other adds an extra injection behind the knee to see if it improves pain relief and recovery.
This study tests two different nerve-block techniques to see which provides better pain control after total knee replacement surgery. The goal is to help you recover more comfortably.
This study compares two types of numbing injections (nerve blocks) to see which provides better pain relief after total knee replacement surgery. If you are 65 or older and having your first knee replacement, you may be able to join.
