Introduction:

Pain control in total knee arthroplasty (TKA) is a determining factor in the patient's rehabilitation process. With conventional peripheral blocking techniques for the posterior compartment, foot drop, and distal motor deficit have been reported. The infiltration between popliteal artery and capsule of the knee (IPACK) block is a promising emerging analgesic technique.

Objective:

To describe analgesic control, opioid consumption, and mobility of patients scheduled for TKA using IPACK block as adjunct analgesic to the femoral block.

Methods:

We conducted a prospective observational cohort study over a 6-month period in adults taken to TKA. Sociodemographic and anthropometric characteristics, laterality, postoperative pain, and opioid consumption, patient and surgeon satisfaction (Likert), postoperative nausea and vomiting, and walk in the first 24hours, were evaluated and reported with a descriptive analysis.

Results:

Twenty-seven patients taken to TKA received an IPACK block. The pain score remained in a mild level during the 48 hours of evaluation. In 73% of the cases, an opioid rescue dose was not required; 81% of the patients managed to walk in the first 24 hours.

Conclusion:

The IPACK block, combined with femoral block and neuraxial anesthesia, turn out to be an excellent analgesic strategy for TKA, achieving adequate pain management, prompt rehabilitation, and early ambulation of the patient.
