Peripheral Nerve Blocks and Postoperative Pain and Mobilization After Total Knee Arthroplasty

NCT07442123 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 90

No results posted yet for this study

Summary

Total knee arthroplasty (TKA) is frequently associated with significant postoperative pain, which may delay early mobilization and negatively affect functional recovery. Peripheral nerve blocks are widely used as part of multimodal analgesia strategies to improve postoperative pain control while minimizing opioid consumption and preserving motor function. Different peripheral nerve block techniques may result in varying analgesic efficacy and mobilization outcomes.

The aim of this prospective observational study is to compare the effects of commonly used peripheral nerve block techniques on postoperative pain control and early mobilization in patients undergoing total knee arthroplasty under spinal anesthesia. Patients receiving fascia iliaca plane block are compared with those receiving a combination of adductor canal block and interspace between the popliteal artery and capsule of the knee (IPACK) block.

The primary outcome is postoperative opioid consumption within the first 24 hours after surgery. Secondary outcomes include postoperative pain scores assessed at predefined time intervals, early mobilization parameters, and opioid-related adverse effects. The findings of this study are intended to contribute to optimizing analgesic strategies and improving early functional recovery following total knee arthroplasty.

Interventions

PROCEDURE

Fascia Iliaca Plane Block

Ultrasound-guided fascia iliaca plane block is performed under sterile conditions prior to surgery as part of perioperative analgesia. Using an in-plane technique with a high-frequency linear ultrasound probe, the needle is advanced beneath the fascia iliaca, and 40 mL of 0.25% bupivacaine is injected incrementally after negative aspiration to achieve spread within the fascia iliaca compartment.

PROCEDURE

Adductor Canal Block + IPACK Block

An ultrasound-guided adductor canal block followed by an interspace between the popliteal artery and capsule of the knee (IPACK) block is performed prior to surgery as part of perioperative analgesia. The adductor canal block is administered using 20 mL of 0.25% bupivacaine injected adjacent to the femoral artery beneath the sartorius muscle. Subsequently, the IPACK block is performed with 20 mL of 0.25% bupivacaine injected into the tissue plane between the popliteal artery and the posterior capsule of the knee under ultrasound guidance.
