Migration Rate for Continuous Adductor Canal Block Catheters After Primary Total Knee Arthroplasty Surgery: a Comparison Between Two Insertion Techniques (NCT07681622)
Migration Rate for Continuous Adductor Canal Block Catheters After Primary Total Knee Arthroplasty Surgery: a Comparison Between the Interfascial Plane Between SArtorious Muscle and FEmoral Artery (ISAFE) and the Out Of Plane Parallel to Saphenous Nerve (OOPS) Techniques: The ISAFE x OOPS Trial
🩺 Plain-English Summary (8th-Grade Level)
Continuous adductor canal block (CACB) is becoming increasingly popular for providing postoperative analgesia following knee arthroplasties. These continuous blocks are provided through inserted nerve catheters and effectively extend the duration of analgesia, thereby reducing opioid consumption. This, in turn, helps minimize opioid-related side effects, promotes early ambulation, and supports earlier discharge. However, catheter migration remains a significant concern, as the catheter tip can become displaced from the adductor canal due to movements associated with ambulation or physiotherapy. In this study, the investigators compare the migration rates of two different techniques for CACB catheters insertion: the Interfascial plane between SArtorious muscle and FEmoral artery (ISAFE) and the Out Of Plane parallel to Saphenous nerve (OOPS) techniques. Pain scores and opioid consumption on postoperative day 1 (POD1) will also be assessed as secondary outcomes. The hypothesis is that both techniques will result in similar migration rates of CACB catheter.
