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.

Design outcomes

Primary

MeasureTime frameDescription
Feasibility of ACL reconstruction surgery under ultrasound guided sciatic nerve block plus femoral nerve block plus obturator nerve block measured with Pain Score on the Visual Analog Scale45 minIf the patient complains for pain \> 4 in VAS and there is no relief with fentanyl administration the anesthesia plan converts to general anesthesia with laryngeal mask

Secondary

MeasureTime frame
