Bilateral adductor canal block catheters in patients undergoing simultaneous bilateral knee arthroplasty: A series of 17 patients

Continuous adductor canal blocks (ACB) have been shown to reduce pain with knee flexion, decrease opioid consumption, and enhance ambulation following total knee arthroplasty [1]. Of the patients who undergo bilateral knee arthroplasties, a small subset have the procedures performed during the same operative encounter rather than a staged procedure [2]. These patients present additional perioperative pain and rehabilitation challenges, in addition to a longer length of hospital stay [2,3]. Adequate analgesia is imperative for immediate postoperative rehabilitation; however, there is a paucity of research regarding regional techniques for simultaneous bilateral knee arthroplasty (SBKA).
