Not Applicable

Completed

• Conditions: Popliteal Plexus Block; Fascia Iliaca Block; Total Knee Arthroplasty
• Interventions: Device: Ultrasound-Guided Popliteal Plexus Block; Device: Ultrasound-Guided Fascia Iliaca block

• Registration Number: NCT05390450
• Lead Sponsor: Tanta University

Brief Summary

This study aims to investigate the effect of the Popliteal Plexus Block versus Fascia Iliaca Block on postoperative pain after total knee arthroplasty.

Detailed Description

The Popliteal Plexus entwines the popliteal artery and vein contiguous to the adductor hiatus in the popliteal fossa and innervates the posterior capsule as well as intraarticular genicular structures. It was recently confirmed in a cadaver study that injection of 10 mL of dye into the distal end of the adductor canal spreads via the adductor hiatus to the popliteal fossa and stains the Popliteal Plexus.

Recently, fascia iliaca block was proposed as a popular analgesic technique which involves local infiltration anesthesia under the fascia of the iliacus muscle. The method depends on the local anesthetics spread beneath the fascia to block the peripheral nerve. It has been proposed to avoid the complications by anesthetizing the femoral nerve remotely from major neurovascular structures and achieve adequate analgesia.

Arm && Interventions

Group	Intervention	Description
Ultrasound-Guided Popliteal Plexus Block	Ultrasound-Guided Popliteal Plexus Block	Patients in this group will receive Popliteal plexus block.
Ultrasound-Guided Fascia Iliaca block	Ultrasound-Guided Fascia Iliaca block	Patients in this group will receive Fascia Iliaca block.

Primary Outcome Measures

Name	Time	Method
Total intravenous (IV) morphine consumption	24 hours postoperatively.	Total intravenous (IV) morphine consumption during the first postoperative 24 hours, postoperatively.

Secondary Outcome Measures

Name	Time	Method
First analgesic request	24 hours postoperatively	Time to first analgesic request after surgery in the form of intravenous morphine in a dose (0.05 mg/kg).
Pain level score	24 hours postoperatively	Pain levels using the numerical rating scale (NRS) of pain intensity (0 = no pain) to (10 = intolerable pain), pain relief is defined as a NRS of 3 or lower. If the score is \>3, the patient will need analgesia in the form of morphine 0.05 mg/kg till it decreases to ≤3. NRS will be assessed and recorded on arrival to Post-Anesthesia Care Unit , 1, 2, 4, 8, 12 and 24 hours postoperatively at rest and on movement (knee flexion) during the first postoperative 24 hours.
Patient's satisfaction level	24 hours postoperatively	Degree of patient satisfaction will be assessed on a 5-point scale; (1= highly satisfied, 2 = satisfied, 3 = neither satisfied nor unsatisfied, 4 = not satisfied, 5 = highly not satisfied)
Rehabilitation	24 hours postoperatively	Rehabilitation (time to ability to sit, time to ability to stand, time to ability to walk, Time to ability to do exercise) will be recorded.
