Combined distal femoral nerve block for pain relief after knee replacement

Official title: Comparative Study Assessing the Efficacy of a Combined Distal Femoral Nerve Block for Postoperative Analgesia Following Total Knee Arthroplasty (TKA)

Run by GCS Ramsay Santé pour l'Enseignement et la Recherche · NCT07629388 · Data updated 2026-11-12

This study tests whether using a combined distal femoral nerve block after knee replacement reduces opioid needs while keeping leg strength intact.

Is this trial a fit for you?

Likely a good fit

Adults undergoing planned total knee arthroplasty who can consent and are eligible for multimodal analgesia.

Probably not a fit

Patients with contraindications to local anesthetics or NSAIDs, those on preoperative opioids, or with conditions excluding participation may not benefit.

What this trial studies

This interventional study compares a combined distal femoral nerve block to a saphenous nerve block alone in adults undergoing total knee arthroplasty. All participants receive standard multimodal pain management. Outcomes include postoperative pain, opioid consumption in recovery, nausea, vomiting, quadriceps strength, time to first standing, and length of hospital stay. The aim is to see if the combined block provides better analgesia without compromising leg strength.

Why it matters

Potential benefit: If successful, patients may experience better pain control with less opioid use and preserved leg strength after knee surgery.

How similar studies have gone: Previous nerve block approaches have shown analgesic benefits in similar orthopedic procedures, but this specific combined distal femoral and saphenous block approach is being tested.
