Abstract: OBJECTIVE: At present, tendon reconstruction of coracoclavicular ligament is still in the initial stage. In each study, the number of cases involving tendon reconstruction of coracoclavicular ligament versus clavicular hook plate is less. For this, the clinical effect comparison of the two treatment schemes is still uncertain. This paper compared the efficacy of coracoclavicular ligament reconstruction with autologous or allogeneic tendon and clavicular hook plate in the treatment of acromioclavicular joint dislocation.
METHODS: A computer was used to retrieve the PubMed, Embase, Cochrane Library, CNKI, Wanfang, and Weipu database. The retrieval time was from the inception of the database to July 2020. Domestic and foreign literature on comparative study of coracoclavicular ligament reconstruction with autologous or allogeneic tendon and clavicular hook plate in the treatment of acromioclavicular joint dislocation was retrieved. Two researchers independently screened the literature according to the inclusion and exclusion criteria, extracted data, and evaluated the risk of bias in the literature. The operation time, intraoperative blood loss, hospital stay, function score, and complications were meta-analyzed with RevMan 5.3 software. According to the treatment, the patients were divided into two groups: autogenous or allogeneic tendon reconstruction coracoclavicular ligament group and clavicular hook plate group. 
RESULTS: Finally, eight articles met the inclusion criteria, including three randomized controlled studies, five retrospective cohort studies and eight articles with high quality, with 382 patients. There were 189 cases of autogenous or allogeneic tendon reconstruction coracoclavicular ligament group and 193 cases of clavicular hook plate group. The longest postoperative follow-up period was about 2.5 years and the shortest was about 6 months. Meta-analysis showed that postoperative Constant-Murley score (MD=3.44, 95%CI: 2.23-4.66), effective rate (OR=9.92, 95%CI: 2.74-35.84), and total postoperative complications (OR=0.11, 95%CI:0.04-0.32) were significantly better in the autogenous or allogeneic tendon reconstruction coracoclavicular ligament group than those in the clavicular hook plate group(P < 0.05). However, operation time (MD=-2.01, 95%CI: -15.96-11.95), intraoperative blood loss (MD=-7.37, 95%CI:-20.00-5.27), and hospital stay (MD=-1.54, 
95%CI: -4.22-1.13) and the visual analogue scale score (MD=0.10, 95%CI:-0.02-0.23) had no significant difference between the two groups (P > 0.05).
CONCLUSION: According to the comparison of limited literature, the effect of coracoclavicular ligament reconstruction with autologous or allogeneic tendon in the treatment of acromioclavicular joint dislocation was better than that of clavicular hook plate group in short-term follow-up, and the success rate of acromioclavicular joint dislocation was improved. The occurrence of postoperative complications was reduced, and it was more conducive to promote the recovery of acromioclavicular joint function.
