Nerve Block and Tourniquet for Knee Surgery Pain Relief
Part of Bones, joints & muscles, Pain clinical trials.
This trial tests whether a nerve block (numbing injection near the thigh) combined with a tourniquet (pressure cuff) after knee replacement surgery reduces pain better than standard care. If it works, it could help patients recover more comfortably with less need for strong pain medications.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 40–85 years old
- Your BMI is between 18–35 kg/m² (a measure of healthy weight range)
- You are in good enough health for surgery (ASA class I–III, meaning no serious medical conditions that prevent surgery)
- You had total knee replacement (full knee replacement, not partial) under spinal anesthesia
- You are having your first knee replacement on one knee only—not a revision or both knees at once
- Your surgery took 3 hours or less
