Nerve block with pain medicine for knee replacement pain
Treatments studied
Part of Pain clinical trials.
This trial tests whether a nerve block injected near the knee (with a long-acting pain medicine) works better for controlling pain after a scheduled knee replacement. It may help reduce pain and the need for stronger pain medicines after surgery.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18–80 years old and have Chinese ethnicity.
- You are having a planned, one-sided (unilateral) first total knee replacement—not a revision and not both knees at once.
- Your overall health status is ASA I–III (generally okay for surgery).
- Your body mass index (BMI) is under 40.
- You can speak and understand Cantonese and can sign written consent.
- You do not have allergies to opioid medicines, local anesthetics (numbing medicines), paracetamol, or NSAIDs (pain/anti-inflammatory medicines).

Other trials that look related to this one.
This trial tests different doses of a long-acting painkiller (liposomal bupivacaine) injected into a nerve block in the thigh to see which dose works best for pain after knee replacement surgery. It may help you have better pain control and recover faster.
This study tests a long-lasting numbing medicine (liposomal bupivacaine) injected around the knee during total knee replacement surgery. It aims to see if this medicine helps control pain and reduce the need for other painkillers after surgery.
This trial tests two different numbing medicines for knee replacement surgery. It compares a long-acting numbing medicine (liposomal bupivacaine) with a standard one (ropivacaine) mixed with other drugs to see which provides better pain control. The goal is to find a way to reduce pain and improve recovery.
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 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 Phase 2 study compares two ways of reducing nerve pain after knee replacement surgery (total knee arthroplasty). It looks at whether steroid-enhanced pain medicine works better than a different numbing injection to improve recovery and comfort.
