Abstract：BACKGROUND:Repair methods for acromioclavicular joint dislocation are various. Different fixation or reconstitution obtains different outcomes. Moreover, various postoperative complications exist, and impact shoulder function. With the development of concept of minimal invasion and rapid generalization of arthroscopy, arthroscopy began to be used in the minimal y invasive treatment of acromioclavicular dislocation, and its effectiveness and safety have been verified. <br> OBJECTIVE:To explore the clinical efficacy of double titanium plate TightRope fixation and anatomic reconstruction of beak lock ligament under arthroscopy in the treatment of acromioclavicular joint dislocation. <br> METHODS:12 patients with type III-VI acromioclavicular joint dislocation were treated with double titanium plate TightRope fixation and anatomic reconstruction of beak lock ligament. After fixation, they were rechecked with X-ray at 1, 6 and 12 weeks. Pain condition was evaluated using Visual Analog Scale. Shoulder joint function was assessed using University of California, Los Angeles (UCLA) grading evaluation after surgery. <br> RESULTS AND CONCLUSION:12 cases had been fol owed up for 4.5-15 months. X-ray examination confirmed that the acromioclavicular joint dislocation was completely reset, and dislocation did not appear again. Significant differences in Visual Analog Scale scores were detected at 1, 6, and 12 weeks after fixation compared with pre-fixation (P<0.05). Significant differences in Visual Analog Scale scores were detectable between 6 and 12 weeks and 1 week after fixation (P<0.05). Significant differences in UCLA scores were found at 1, 6 and 12 weeks after fixation compared with pre-fixation (P<0.05). Significant differences in UCLA scores were seen at 6 weeks after fixation compared with 1 week (P<0.05). These results indicated that TightRope fixation and anatomic reconstruction of beak lock ligament under arthroscopy for acromioclavicular joint dislocation is stable, obtains smal trauma, and can be easily accepted by patients. Moreover, patients can receive early joint functional exercise so as to restore joint function better, which do not damage the joint surface, without shoulder peak impact or secondary surgery. Curative effect is satisfied.
