Brief Summary

The ideal pain management for knee surgery should provide excellent analgesia while minimizing opioid consumption and allowing early mobilization and rehabilitation. The use of the continuous technique in ACB allows the delivery of a larger quantity of local anaesthetic into the adductor canal than in the single-shot technique. The usual approach for ultrasound-guided ACB catheter insertion is through short-axis in-plane approach in which the ultrasound transducer is applied horizontally over the femoral artery and saphenous nerve. In this approach, the catheter is inserted through a 90-degree angulation with the nerve which might make the catheter insertion difficult. In the new oblique position, the catheter will be inserted in a less than 90-degree angulation. This study speculates that decreasing the angle of catheter insertion will make catheter insertion easier and faster.
