Overview

Brief Summary

The goal of this clinical trial is to verify the effect of suprascapular nerve block and axillary nerve block in relieving postoperative pain after arthroscopic rotator cuff repair.

Are there differences in visual analog pain scale and patient's satisfaction? Are there differences in mean plasma pain related cytokines? The participants will undergo preemptive ultrasound guided suprascapular nerve block and axillary nerve block using each 0.75% ropivacaine 10mL or each 0.9% saline 10mL.
