Nerve block comparison for knee replacement pain
Part of Brain & nervous system, Pain clinical trials.
This study compares two numbing techniques (nerve blocks) for pain relief after knee replacement surgery. The goal is to find which one works better and helps you recover with less pain.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are scheduled to have a total knee replacement on just one knee (not a second surgery or both knees at once).
- You do not have allergies to numbing medications or problems with bleeding or blood thinners.
- You do not have nerve damage, muscle weakness, or a history of severe organ problems (liver, kidney, or heart failure).
- You have not been using strong pain medicines (opioids) regularly or had substance abuse issues.
- You are considered healthy, or have mild to moderate health issues that are well managed (ASA class I–III).

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 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.
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 ways to manage pain after knee replacement surgery: one uses a local anesthetic injection around the knee, and the other adds an additional nerve block. The goal is to see which method provides better pain relief and 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.
