Summary
The ultrasound-guided selective blockade of the saphenous nerve in the adductor canal
provides effective analgesia and reduces postoperative pain in patients undergoing
arthroscopic medial meniscectomy. Selective blockade of the saphenous nerve in the adductor
canal provides effective analgesia without quadriceps muscle weakness. It has been shown that
the adductor canal block (ACB) block increases the spread of local anesthetics in a distal
and proximal way. Therefore, the proximal spread of local anesthetics may cause possible
quadriceps weakness. The distal spread of local anesthetics may increase analgesic effect via
sciatic nerve. The different volumes for ACB is a topic of discussion. The aim of this study
is to compare the different volumes of US-guided ACB performing for postoperative analgesia
management after total knee arthroplasty surgery.
