Tips for the IPACK Block

August 29, 2023

IPACK stands for Infiltration of local anesthetic between the Popliteal Artery and Capsule of the Knee. It is a motor-sparing technique that anesthetizes the small articular sensory nerves from the popliteal plexus and obturator nerve resulting in analgesia of the posterior knee capsule.

Here are 3 steps to successfully perform an IPACK block

  1. Place the transducer transversely over the medial aspect of the knee, 2-3 cm above the patella.
  2. Slide the transducer proximal and distal to identify the distal femoral shaft and popliteal artery.
  3. Insert the needle in-plane, from the anteromedial aspect of the knee, toward the space between the popliteal artery and femur, and inject 15-20 mL of local anesthetic.
