Brief 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 usage of tourniquet during performing 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 timing of the tourniquet inflation for ACB is a topic of discussion.The aim of this study is to compare the different times of US-guided ACB performing for postoperative analgesia management after arthroscopic knee surgery.

Study Arms (3)

Group Pre = preoperatively before inflation of the tourniquet

ACTIVE COMPARATOR

ACB will be performed under general anesthesia in the supine position. Patients will be administered ibuprofen 400 mgr IV every 8 hours in the postoperative period. A patient controlled device prepared with 10 mcg/ ml fentanyl will be attached to all patients with a protocol included 10 mcg bolus without infusion dose, 10 min lockout time and 4 hour limit

Other: Group Preoperatively Adductor Canal Block

Group Pre-T = preoperatively after inflation of the tourniquet

Interventions

Group Preoperatively Adductor Canal Block OTHER

The ACB will be performed preoperatively before inflation of the tourniquet. After identifing the adductor canal, by using the in-plane technique, the probe will be placed at the mid-thigh, half the distance between the inguinal crease and the patella, for block location. The superficial femoral artery will be visualized dorsal to the sartorius muscle. Then, the probe will be remowed to distally. At this level, the hyperechoic view of the saphenous nerve will be visualized lateral and anterior to the artery in the subsartorial region. 5 mL of saline will be injected to confirm the proper injection site, and then a dose of 0.25% bupivacaine 30 mL will be injected here.

Group Postoperatively Adductor Canal Block OTHER

The ACB will be performed postoperatively. After identifing the adductor canal, by using the in-plane technique, the probe will be placed at the mid-thigh, half the distance between the inguinal crease and the patella, for block location. The superficial femoral artery will be visualized dorsal to the sartorius muscle. Then, the probe will be remowed to distally. At this level, the hyperechoic view of the saphenous nerve will be visualized lateral and anterior to the artery in the subsartorial region. 5 mL of saline will be injected to confirm the proper injection site, and then a dose of 0.25% bupivacaine 30 mL will be injected here.
