Single Shot Versus Continuous Adductor Canal Block in Patients Undergoing Total Knee Arthroplasty

Overview

Adductor canal block (ACB) has emerged as an option for postoperative regional analgesia in patients undergoing total knee arthroplasty (TKA).

Various approaches to the performance of peripheral nerve blocks for postoperative pain control in patients undergoing TKA have been described in the literature. These approaches include lumbar plexus block, femoral nerve block (FNB), with or without a sciatic nerve block, and most recently the ACB. FNB is a commonly used modality for postoperative analgesia after TKA. It is considered by some as the gold standard or the cornerstone of postoperative analgesia after TKA. However, FNB reduces quadriceps muscle strength essential for mobilization and active contribution in any physical rehabilitation program. Quadriceps weakness places the patients at risk of falling. which may be detrimental to postoperative recovery. The ACB has recently emerged as an appealing alternative to FNB as it is predominately a sensory nerve block of a more distal branch of the femoral nerve ( the saphenous nerve).
