Persistent Post Surgical Pain After Total Knee Arthroplasty

Not Applicable

Recruiting

• Conditions: Knee Arthropathy
• Interventions: Procedure: continuous peripheral nerve block

• Registration Number: NCT06182059
• Lead Sponsor: Policlinico di Monza SpA

Brief Summary

Patients undergone total knee replacement are randomized to receive a "fast track" regional anesthesia protocol or a "traditional" regional anesthesia continuous infusion by both a femoral and sciatic catheter to assess if this latter technique may reduce persistent postoperative pain six months after surgery

Detailed Description

Patients undergone to primary total knee replacement with spinal anesthesia are randomized to receive a continuous adductor canal block infusion + an ipack block or a continuous femoral nerve block + a continuous sciatic nerve block just at the end of surgery. Both group will receive a multimodal analgesia with paracetamol, ketorolac, desametasone and morphine as a rescue.
