Abstract Purpose: To detect coracoid tunnel widening after arthroscopic fixation of acute acromioclavicular joint (ACJ) dislocation using TightRope system and its correlation with loss of reduction and the functional scores.~Methods: From July 2016 to Dec 2018, a prospective study was performed at our hospital. Twenty-three patients with acute grade III-V ACJ dislocation were included in the study. Arthroscopic double tight-rope repair of the ACJ was performed. Coracoid tunnel widening was measured by computed tomography (CT) and coraco-clavicular distance was measured on the x-ray immediately post-operative and at 12 months. Constant Shoulder Score, Oxford Shoulder Score, Nottingham Clavicle Score and Visual analogue scale were used as outcome measures at 12 months.~Level of evidence IV Keywords Acute acromioclavicular joint injury .
