Nerve block for pain after knee replacement
Part of Bones, joints & muscles, Pain clinical trials.
This study tests whether a special nerve block (called an AFCN proxy block) helps control pain after knee replacement surgery. It may reduce the need for strong painkillers and improve recovery.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 45 to 90 years old.
- You are having a first-time total knee replacement on only one knee for arthritis.
- You are generally healthy (low anesthetic risk) and can rate your pain on a 0–10 scale.
- You do not take high doses of daily strong painkillers (more than 30 mg of morphine equivalent per day).
- You have no nerve damage in your legs, no allergy to the numbing medicine ropivacaine, and no bleeding problems that would prevent a nerve block.

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 study tests a nerve-blocking injection to reduce pain after knee replacement surgery. The goal is to help patients manage pain better in the days following their operation using a combination pain-control approach.
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 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 compares two different nerve-block methods to see which provides better pain relief after total knee replacement surgery. It may help reduce pain and improve recovery.
This trial tests adding an extra nerve block (IPACK) to the usual adductor canal block to see if it improves pain, recovery, and inflammation after total knee replacement surgery.
