Comparison of Ultrasound-Guided Lumbar ESPB and ACB for Knee Arthroplasty
Sponsor: Bursa City Hospital
Summary
Total knee arthroplasty (TKA) is a surgical procedure frequently associated with moderate-to-severe postoperative pain. While Adductor Canal Block (ACB) has demonstrated analgesic efficacy in TKA, the Erector Spinae Plane Block (ESPB) is also being utilized as part of multimodal analgesia for postoperative pain management in lower extremity surgeries. Currently, there is a gap in the literature as no studies have directly compared the efficacy of ACB and ESPB for pain management following TKA. The primary objective of this study is to compare the efficacy of these two analgesic methods in the context of postoperative analgesia management after total knee arthroplasty.

Postoperative analgesia management
After determining the L5-S1 level with ultrasound guidance, an 80 mm block needle (Stimuplex Ultra®, Braun, Melsungen, Germany) will be advanced in a cranio-caudal direction. Following hydrodissection, 30 ml of 0.25% bupivacaine local anesthetic solution containing 7.5 mcg of epinephrine (1:200,000) will be administered.
Postoperative analgesia management
After identifying the adductor canal with a high-frequency linear US probe (GE ML6-15-D Matrix Linear), 30 ml of 0.25% bupivacaine local anesthetic solution containing 7.5 mcg of epinephrine (1:200,000) will be administered into the adductor canal using an 80 mm block needle (Stimuplex Ultra®, Braun, Melsungen, Germany).
