Nerve block for pain after knee replacement surgery
Part of Brain & nervous system, Pain clinical trials.
This trial tests whether adding a nerve block (a numbing injection near the nerve) to the usual pain plan can better control pain after a total knee replacement. The goal is to help you recover with less pain and fewer side effects.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be 18 years or older.
- You must be scheduled for a total knee replacement (a surgery to replace the knee joint).
- You need to be covered by French social security (health insurance).
- You must be under 50 kilograms (about 110 pounds) in weight—actually, the trial requires you weigh at least 50 kg, so if you are below that, you cannot join.
- You cannot be taking opioids (strong painkillers like morphine) or certain nerve pain medications (antidepressants or gabapentinoids) before the surgery.
- You must not have any allergies to the pain medications or anesthetics used in the trial.

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 trial tests a nerve block that helps manage pain after total knee replacement surgery. It may reduce the need for strong painkillers and improve your recovery. The study is for people having their first knee replacement on one knee.
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 study compares two ways to manage pain after knee replacement surgery: local numbing medicine injected into the knee versus numbing several nerves in the leg. The goal is to find which method provides better pain control and recovery.
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 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.
