Abstract:Objective To explore the difference of efficacy and safety between arthroscopic anterior glenohumeral joint release and conservative treatment for frozen shoulder.Methods 98 patients with frozen shoulder from October 2021 to October 2022 were prospectively selected as the study subjects. They were randomly divided into group A and group B. 48 patients in group A were treated with anterior glenohumeral joint release under shoulder arthroscopy, and 50 patients in group B were treated conservatively. The clinical effects of the two groups were compared. The Constant-Murley shoulder function score, shoulder range of motion, visual analogue scale (VAS), active range of motion (AROM) score and Pittsburgh sleep quality index (PSQI) were compared before and after treatment in the two groups, and the complications of the two groups were observed.Result The total effective rate of clinical treatment in group A was 93.75% (45/48), which was significantly higher than that in group B 76.00% (38/50); After 3 months of treatment, the shoulder joint function score of group A was higher than that of group B, the activity indexes of flexion, internal rotation, abduction and external rotation in two groups were increased after treatment, and group A was higher than group B, VAS and PSQI scores were lower and AROM scores was higher in group A than in group B, the differences were statistically significant (P < 0.05).Conclusion The anterior glenohumeral joint release under arthroscopy has a better therapeutic effect on patients with frozen shoulder than conservative treatment. It can significantly improve the function and activity of the shoulder joint, reduce joint pain, improve sleep quality, and has no significant complications. It is worthy of clinical reference.
