Clinical analysis of TightRope in the treatment of Rockwood type III acromioclavicular joint dislocation

Objective To analyze the technical points of TightRope in the treatment of acromioclavicular joint dislocation and summarize relevant experience. Methods From January 2014 to April 2018, 77 patients with Rockwood type Ⅲ acromioclavicular dislocation were treated with TightRope to reconstruct coracoclavicular ligament. There were 6 cases of plate prolapse and loosening after the operation. The reasons for the failure of the operation were analyzed. Results All the patients were follow-up for 3 to 32 months, with an average of 14.3 months. The Constant score was 93.86±5.59 three months after the operation. The Constant score was 79.17±7.33 three months after the operation in 6 cases of failure. The causes of failure included deviation of tunnel construction in 3 cases, improper operation in 2 cases and excessive reduction of acromioclavicular joint in 1 case. Conclusion The application of TightRope in the treatment of acromioclavicular joint dislocation has the advantages of less trauma, less pain and no need for secondary operation. However, there are still some shortcomings, which need further long-term follow-up. Key words: Acromioclavicular joint; Dislocations; Clinical analysis; Constant score
