Nerve blocks for knee replacement pain relief
Part of Bones, joints & muscles, Pain clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are having a first-time total knee replacement surgery on one knee only
- Your doctor plans to use spinal anesthesia (numbing medicine injected into your spine)
- You are in generally good health (ASA class I, II, or III—your surgeon can confirm this)
- You do not have a bleeding disorder or take blood-thinning medications you cannot stop
- You are not currently taking opioid pain medications regularly or have chronic pain conditions
- Your BMI (body mass index) is 35 or lower

This trial tests two types of numbing injections (nerve blocks) around the knee to help manage pain after total knee replacement surgery. The goal is to see if these injections reduce pain and improve recovery compared to standard pain treatment.
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 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 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.
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 types of numbing injections (nerve blocks) used during knee replacement surgery to see which one helps your thigh muscle recover strength faster. Both are standard care options; the trial tests which works better for early movement after surgery.
