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