Assessment of Adductor Canal Blockade in Anterior Cruciate Ligament Surgery

Not Applicable

• Conditions: Surgery of Arthroscopic Anterior Cruciate Ligament Repair
• Interventions: Drug: Analgesic nerve blockade (Ropivacaine); Procedure: Arthroscopic surgical repair of the anterior cruciate ligament

• Registration Number: NCT02419261
• Lead Sponsor: University of Liege

Brief Summary

Assessment of sensory and motor blockade of adductor canal blockade performed for anterior cruciate ligament repair in comparison with femoral nerve blockade.

Detailed Description

The adductor canal blockade is a reliable technique for analgesia after knee surgery. It is a safe technique, avoiding muscle weakness, and by this way limiting the risk of fall. Injection of local anaesthetics in the adductor canal does not block the sole saphenous nerve. Demonstration of a proximal spreading, around the branches of the femoral nerve have been made. The aim of this study is to assess a possible spreading from the adductor to the the popliteal fossa, where sciatic nerve and its branches are located. Pinprick test all around the knee and the leg, combined with motor assessment of the muscle of the leg and the ankle will be realised. This assessment was compared with femoral nerve blockade, classically used for analgesia after this kind of surgery (anterior cruciate ligament repair)

Group	Intervention	Description
Adductor Canal Blockade	Analgesic nerve blockade (Ropivacaine)	In this group, patient will benefit of an ultrasound guided adductor canal blockade (20 ml of Ropivacaine 0.75%) as analgesic nerve blockade for their surgery of anterior cruciate ligament repair
Femoral Nerve Blockade	Analgesic nerve blockade (Ropivacaine)	In this group, patient will benefit of an ultrasound guided femoral nerve blockade (20 ml of Ropivacaine 0.75%) as analgesic nerve blockade for their surgery of anterior cruciate ligament repair
Adductor Canal Blockade	Arthroscopic surgical repair of the anterior cruciate ligament	In this group, patient will benefit of an ultrasound guided adductor canal blockade (20 ml of Ropivacaine 0.75%) as analgesic nerve blockade for their surgery of anterior cruciate ligament repair
