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.

Detailed description

In our clinic, various regional blocks are applied for analgesia or anesthesia purposes in many surgeries, including knee surgery. For knee surgery, adductor canal block, lumbar epidural analgesia, genicular block, erector spinae plane block, and iPACK block can be used. In our clinic, erector spinae plane block and adductor canal block are routinely applied to knee surgery patients. In our study, we aimed to contribute to the literature by comparing patient satisfaction surveys and pain follow-up in patients undergoing knee arthroplasty who received adductor canal block versus lumbosacral erector spinae plane block, both applied with PROSPECT protocols for postoperative analgesia.

Conditions

• Total Knee Anthroplasty

Interventions

Type	Name	Description
OTHER	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.
OTHER	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).
