Brief Summary

Total knee arthroplasty (TKA) is a frequent performed surgery. Adequate pain management is an important feature. Analgesic duration of single shot nerve blocks is limited to no more than 24h. Conversely, the use of continuous nerve block (CNB) through a perineural catheter and infusion of local anesthetic may increase duration of analgesia and provide better outcomes. Continuous adductor canal block (CACB) has been proven superior when compared to single-injection adductor canal block (SACB) for TKA analgesia. However, safety concerns such as intravenous insertion, nerve injury, or catheter displacement must always be considered. The purpose of this study is to evaluate the Inter-fascial Plane between SArtorius Muscle and FEmoral Artery (ISAFE) approach for adductor canal catheter placement, in terms of catheter dislodgment, clinical effectiveness and complications, in comparison with the classical approach, as TKA postoperative analgesia modality. We hypothesize that ISAFE approach can result in a smaller rate of dislodgments in the way that it increases the clinical benefit of CACB.
