One hundred and eighty patients who underwent unilateral tri-compartmental total knee arthroplasty (TKA) for primary osteoarthritis were randomized to receive either single filtration adductor canal block alone (ACB; n=60), continuous adductor canal block (CACB; n=60), or single infiltration adductor canal block with IPACK block (interspace between the popliteal artery and posterior capsule of the knee; n=60). The primary outcome of this trial was to assess the effects of these blocks on postoperative pain at rest using a visual analog scale (VAS). The secondary outcomes of this trial were to measure opioid consumption, movement, and range of motion at the time of discharge. The results of this trial showed that CACB was better for pain management post-operatively, reduced opioid consumption, and had better range of motion when compared to ACB and ACB+IPACK.
