    Six hours after surgery

Secondary Outcomes (2)

  • Pain Score Measurement Reported by Patients

    24 hours after surgery

  • Quality of Recovery (QoR) Score

    one week, measurements are obtained at 24 hours, 48 hours, and one week

Study Arms (2)

ACB + iPACK

EXPERIMENTAL

Patients scheduled for TKA will be randomized to receive an adductor canal block with an additional ultrasound guided injection of local anesthetic between the popliteal artery and the capsule of the knee (iPACK).

Drug: ultrasound guided injection of local anesthetic between the popliteal artery and the capsule of the knee (iPACK)

ACB w/o iPACK

NO INTERVENTION

Patients enrolled in this arm will receive the standard of care adductor canal block (ACB) prior to their total knee arthoplasty.

Interventions

nerve block for posterior knee pain after a TKA.

Also known as: iPACK
ACB + iPACK
