Nerve blocks for better leg strength after knee replacement
Part of Pain clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are at least 20 years old and scheduled for a primary (first-time) knee replacement on one leg
- Your overall health is stable enough for surgery (ASA physical status I–III)
- You can walk on your own without help before surgery
- You can straighten your knee to less than 30 degrees before surgery (no tight knee contracture)
- You have no severe allergies to numbing medications or neurological conditions affecting leg strength
- You understand the study and can give written permission to participate

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 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.
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 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 study tests whether adding a second nerve block in the back of the thigh to the usual thigh block provides better pain relief after knee replacement surgery. If you're having a knee replacement, this might help reduce pain and improve recovery.
