Comparing two nerve block methods for pain after knee replacement
Part of Pain clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 75 years old.
- You are scheduled for a total knee replacement (first time, not a revision).

- You do not have chronic pain or take pain medication regularly.
- You do not have bleeding or clotting problems, and you are not allergic to numbing medicines.
- You have no nerve or muscle disease in the leg being operated on, and you can cooperate with pain assessments after surgery.

This study compares two different numbing techniques to see which provides better pain control during and after total knee replacement. It may help find a way to reduce 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 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 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 types of nerve blocks to see which provides better pain relief after knee replacement surgery. If you qualify, you'll receive one of these blocks to help manage your pain after the operation.
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.
