Knee replacement pain relief with and without extra nerve block
Part of Bones, joints & muscles, Pain clinical trials.
This study compares two types of nerve blocks for pain control after knee replacement surgery. One uses a standard block near the knee, and the other adds a second block to see if it improves pain relief and recovery.
Summary written for real people, not researchers, by Clin2.
Who can take part

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 of numbing the knee after total knee replacement surgery to see which gives better pain relief. If you are having this surgery and want to manage pain without strong opioids, this trial might help you understand your options.
This study compares two ways of numbing the thigh area (called a nerve block) before a double knee replacement, to see which one gives better pain relief and recovery. You will receive one method for one knee and the other method for the other knee, so you can help doctors find the best approach.
This study compares two ways to manage pain after knee replacement surgery: one uses a nerve block around the knee (adductor canal block), and the other adds an extra shot or nerve block. The goal is to see which approach works better for controlling pain and helping you recover.
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.
