Pain Management After Adductor Canal Block for Total Knee Arthroplasty

Pain Management and Functional Recovery After Adductor Canal Block Combined With iPACK Block for Total Knee Arthroplasty. A Prospective, Randomized, Double-blinded Clinical Trial.

This randomized, double-blinded, placebo-controlled trial sought to evaluate the efficacy of the iPACK block with Adductor Canal Block on postoperative pain, functional recovery and NLR and PLR levels.

The Interspace between the popliteal artery and capsule of the posterior knee, or iPACK block, together with the Adductor Canal block (ACB), has been described and shows promise in providing analgesia to the knee joint. However, the effect of these two blocks on postoperative pain levels, functional recovery, and stress response is uncertain. This study compares a preoperative iPACK and ACB block to Sham blocks before total knee arthroplasty under spinal anesthesia.

Inclusion Criteria:

• Patients > 18 years old undergoing unilateral total knee arthroplasty

Exclusion Criteria:

• refusal to participate
• < 18 yo
