The purpose of this study was to evaluate mid- and long-term clinical radiologic outcomes arthroscopic coracoclavicular ligament reconstruction (ACCLR) with an artificial for acute dislocation the acromioclavicular joint (ACJ).Twelve male patients (average age at time surgery: 40.8 years, range: 21-64 years) underwent ACCLR ACJ type III or V according Rockwood classification. Arthroscopic surgery performed patient under general anesthesia interscalene brachial plexus block in beach-chair position. Reduction manually using elevator control imaging intensifier. fixed temporarily a Kirschner wire. Bone tunnels coracoid process clavicle were made cannulated drill. An pulled out through bone on upper surface staple interference screw, undersurface Endobutton. shoulder immobilized brace 4 weeks postoperatively, rehabilitation started first postoperative week. Japan Shoulder Society Acromioclavicular Joint Function Assessment (JSS-ACJ) score used evaluation outcomes, plain radiographs after minimum follow-up period 5 years postoperatively.The average 106.3 months (range: 62-128 months). JSS-ACJ 97.2 points 92-100). seven who had been playing sports before injury all returned their pre-injury level. No complained pain dysfunction daily activities, work, sports. There no complications such as neurovascular injuries during surgery, infection, foreign body reaction from ligament. Radiographs final showed subluxation non-symptomatic osteoarthritic changes two patients, respectively.ACCLR is useful surgical procedure that gives satisfactory follow-up. can stabilize vertical instability ACJ. If horizontal direction remains, repair should be added prevent
