Adductor Catheter Insertion Through the Knee Arthrotomy: Can This Technique Be as Safe and Effective as Ultrasound-Guided Insertion?

Background: Early postoperative pain following total knee arthroplasty remains challenging. We devised a technique for inserting a continuous catheter intraoperatively in the adductor canal and aimed to compare its efficacy and safety with that of an ultrasound-guided anesthetist-administered continuous catheter.

Methods: This single-center, single-surgeon, prospective, interventional, randomized controlled trial included 330 patients, who were randomized into two groups with similar preoperative status and demographics.
