The ultrasound‐guided iPACK block with continuous adductor canal block for total knee arthroplasty

Abstract

SummaryWe report a case of pre‐operative ultrasound‐guided local anaesthetic infiltration of the interspace between the popliteal artery and the capsule of the posterior knee (iPACK), in a 75‐year‐old male undergoing total knee arthroplasty. This was supplemented with postoperative adductor canal block using a continuous catheter technique. We assessed postoperative analgesia at rest and during active flexion of the knee, opioid consumption, motor and functional recovery, and patient satisfaction, for three postoperative days. This technique provided effective motor‐sparing analgesia, and was associated with excellent patient satisfaction.
