Abstract:
Objective:To investigate the clinical effect of arthroscopic combined fixation of acromioclavicular joint in the treatment of acute acromioclavicular dislocation.Methods:A retrospective controlled analysis was conducted on 40 patients with acute dislocation of the acromioclavicular joint were treated in Qinhuangdao First Hospital of Hebei Medical University from February 2021 to December 2023. There were 30 males and 10 females, aged from 22 to 54 years, with an average age of (40.55±7.75) years. The patients were divided into two groups based on the surgical method used. The observation group included 19 patients who were treated with Tightrope and suture to reconstruct the coracoclavicular ligament and acromioclavicular ligament, while the control group included 21 patients who were treated with Tightrope to reconstruct the coracoclavicular ligament only. All patients were followed up postoperatively, and their preoperative and postoperative data were recorded. The visual analogue scale (VAS) for pain, Constant score and coracoclavicular distance values of the two groups of patients before surgery and one year after surgery were recorded and compared. The changes of the internal fixation devices were observed. The measurement data with normal distribution were expressed as mean±standard deviation ( ± s), and the t-test was used for comparison between groups, skewed continuous data were presented as [ M( Q1, Q3)], and intergroup comparisons were performed using the Mann-Whitney U test; the count data were expressed as cases and percentages [ n(%)], and the chi-square test was used for comparison between groups. Results:There was no significant difference in the general information (gender, age, affected side, time from injury to operation) between the two groups ( P>0.05). The last follow-up showed that two patients in the control group had early failure of the implant, one of whom had an infection after surgery, and one of whom had obvious displacement of the Tightrope early on. All patients in the observation group were healed by first intention, without any postoperative early complications such as wound infection, early failure of internal fixation, etc. There was no statistically significant difference in the VAS score between the two groups ( P>0.05); the Constant score 85(84, 89) of the observation group was higher than that of the control group 82(80, 85), and the difference was statistically significant ( P<0.05); the VAS score and Constant score of both groups after surgery were significantly improved compared with those before surgery ( P<0.05). One year after operation the coracoclavicular distance was 8.5(8.0-8.8) mm in observation group, and 10.3(9.7, 10.6) mm in control group ( P<0.05). Conclusions:The method of reconstructing the coracoclavicular ligament and acromioclavicular ligament complex fixation with Tightrope and suture using arthroscopy is reliable and has fewer postoperative complications. It is a better method than using Tightrope alone to fix the coracoclavicular ligament for the treatment of acute Rockwood Ⅲ to Ⅴ type acromioclavicular dislocation.
