Ultrasound Guided Obturator Nerve Block for Anterior Cruciate Ligament Reconstruction (ACL)

Not Applicable

Completed

• Conditions: Anterior Cruciate Ligament; Surgery
• Interventions: Other: Sciatic nerve block, posterior lumbar plexus block; Other: Sciatic, femoral, obturator nerve blocks

• Registration Number: NCT01194505
• Lead Sponsor: Larissa University Hospital

Brief Summary

Anterior Cruciate Ligament ACL reconstruction can be performed under the combination of posterior lumbar plexus block plus sciatic nerve block. The investigators can have the same outcome by performing instead of posterior lumbar plexus block more peripheral nerve blocks. More specifically under the combination of sciatic nerve block plus femoral nerve block plus obturator nerve block.
