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?
Age 18-45 years old
Acute AC joint injury rockwood classification III, IV and V
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
Parallel
K-wire
DeviceK-wire No. 2.0 insertion was done additionally from arthroscopic assisted CC-stabilization by inserting K-wire from acromion process to distal clavicle.
Acromioclavicular Joint Instability (ACJI) score
Functional outcome, Rated from 0-100, higher score means better function of the shoulder
Coracoclavicular (CC) distance diference
Radiologic outcome
Gleno-acromio-clavicular angle (GACA) difference
Radiologic outcome
Constant score
Functional outcome, Score from 0-100, Higher score means better shoulder function
DASH score
Functional outcome, Score from 0-100, 0 means no disabillity, 100 means most severe disabillity
