Arthroscopic Assisted CC Stabilization Alone VS Additional K-wire Fixation for Acute Acromioclavicular Joint Injury

This RCT study is designed for comparing functional outcomes and radioligic outcomes between intervention group (Arthroscopic assisted CC-stabilzation with additional K-wire fixation) and control group (Arthroscopic assisted CC-stabilzation alone) for acute ACJI. The main question it aims to answer is: \- Does Arthroscopic assisted CC-stabilization with additional K-wire fixation provide different outcomes in functional outcomes, CC-distance and GACA difference compare with arthroscopic assisted CC-stabilization alone in acute acromioclavicular joint injury?
