Combined Distal Femoral Nerve Block for Pain Control After Knee Replacement (FEM-COMB)
4 de junio de 2026 actualizado por: Ramsay Générale de Santé
Comparative Study Assessing the Efficacy of a Combined Distal Femoral Nerve Block for Postoperative Analgesia Following Total Knee Arthroplasty (TKA)
The goal of this clinical trial is to see whether a combined distal femoral nerve block improves pain relief after total knee replacement in adults having planned surgery. The main questions it aims to answer are:
- Does the combined distal femoral nerve block reduce the amount of opioid needed in the post-anesthesia recovery room?
- Does it preserve quadriceps muscle strength while improving postoperative pain control?
Researchers will compare the combined distal femoral nerve block to a saphenous nerve block alone to see if the combined block provides better analgesia without reducing leg strength.
Participants will:
- Receive either the combined distal femoral nerve block or the saphenous nerve block alone before surgery.
- Also receive standard multimodal pain management, including anesthesia, surgical site infiltration, and postoperative pain medications.
- Be assessed for pain, opioid use, nausea and vomiting, quadriceps strength, time to first standing, hospital stay length, and patient satisfaction from surgery until discharge.

Experimental: Combined Distal Femoral Nerve Block
Participants receive an ultrasound-guided combined distal femoral nerve block targeting the saphenous nerve, vastus medialis nerve, and anterior femoral cutaneous nerves, using ropivacaine 2 mg/mL, 40 mL total, with clonidine 30 micrograms perineural and dexamethasone 8 mg IV.
They also receive surgical site infiltration, general anesthesia, and standard multimodal analgesia.
