Genicular Nerve Block Versus IPACK Block for Knee Arthroscopic Surgery

ultra-sound visualization of the popliteal artery and posterior surface of the distal femur then the image of the femoral condyles and popliteal artery will be obtained. A needle with a tip length of 100 mm will be inserted in a medial to the lateral plane parallel to the femur in the middle area between the popliteal artery and femur,20 ml local anesthetic solution will be given into this space with adequate and equal distribution of anesthetic agent

ultra-sound transducer placed parallel to the femur shaft and the epicondyle will be identified, the superomedial superolateral and inferomedial genicular arteries, which follow a similar route with each genicular nerve will be visualized close to the periosteal areas, A20G needle with a tip length of 50mm will be directed in the plane of the US probe in the long axis view. After confirming placing of the needle next to each genicular artery a total amount of 20 ml local anesthetic in equal increments at multiple sites.
