[Objective] To compare the effect of suture anchor and loop plate for treatment of acromioclavicular dislocation. [Methods] 65 patients with Tossy type Ⅲ acromioclavicular joint dislocation were treated with the surgery of ligament reconstruction. They were divided into suture anchor group (32 cases) and loop plate group (33 cases). The clinical and imaging results were compared between two groups. [Results] The operation time, blood loss and total length of incision in suture anchor group were less than those in loop plate group（P<0.05）. VAS scores decreased and Constant-Murley scores increased postoperatively（P<0.05）, and there was no significant difference in VAS scores and Constant-Murley scores between two groups（P>0.05）. The acromioclavicular distance and coracoclavicular distances of the two groups both became smaller postoperatively（P<0.05）. There was no significant difference in acromioclavicular distance between two groups at the same time（P>0.05）. There was no significant difference in coracoclavicular distances between two groups after 2 days of the operation（P>0.05）. The coracoclavicular distance in suture anchor group was bigger than that in loop plate group after 2 years of the operation（P<0.05）. [Conclusions] Suture anchor reconstruction and loop plate reconstruction both can alleviate shoulder pain and restore shoulder joint function. Suture anchor reconstruction can not maintain the coracoclavicular distance as well as loop plate reconstruction. However, suture anchor reconstruction has the advantages of less trauma and less time.
