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

Acromioclavicular joint injury (ACJI) is one of the most common injury of shoulder joint. Most common mechanism of injury is from direct force apply to the affected shoulder, in adduction position, in acromion process area. Most of the intervention that have been used for treat ACJI are focused on pain control, maintain the strength of the joint, no limitation in daily life activity and full range of motion of affected shoulder. Operative treatment is indicated in ACJI Rockwood classification grade III, IV, V, and VI. Nowadays there are over 60 surgical techniques without gold standard. Arthroscopic assisted CC-stabilzation is one of the most popular technique that has been used for ACJI.

This RCT study is designed for comparing functional outcomes (ACJI score, VAS, Constant score and DASH score) and radioligic outcomes (CC-distance difference, GACA difference) 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?

Inclusion criteria

• Age 18-45 years old
• Acute AC joint injury rockwood classification III, IV and V

Exclusion criteria

• History of underwent previous ipsilateral shoulder surgery
• Specific active associated ipsilateral injury (Rib fractures, clavicel fractures, scapula fractures and base of coracoid fractures)
• Onset of injury more than 3 weeks
• Cannot underwent arthroscopic assisted CC-stabilization surgery
