Abstract:Objective To investigate the efficacy and safety of conventional open Latarjet surgery, arthroscopic Latarjet surgery, arthroscopic Bankart repair combined with Remplissage surgery in the treatment of recurrent anterior shoulder dislocation (RASD) with scapula glenoid bone defect > 15% and meshing Hill-Sachs lesion.Methods The clinical data of 65 patients with RASD with 15%~25% scapula glenoid bone defect and meshing Hill-Sachs lesion admitted to our hospital from January 2022 to December 2024 were retrospectively analyzed. They were divided into group A, group B, and group C according to different surgical methods. Among them, group A underwent conventional open Latarjet surgery (n = 18), group B underwent arthroscopic Latarjet surgery (n = 21), and group C underwent arthroscopic Bankart repair combined with Remplissage surgery (n = 26). The surgical conditions, preoperative and postoperative scores of related scales [visual analogue scale (VAS), Constant-Murley shoulder score, the University of California Los Angeles (UCLA) shoulder score], shoulder range of motion, postoperative complications and recurrence were compared among the three groups.Results Operation time: group B was longer than group A and group C (P < 0.05), and group A was longer than group C (P < 0.05). Intraoperative blood loss and hospital stay: group A was more or longer than group B and group C (P < 0.05), group B was more or longer than group C (P < 0.05). The VAS scores of the three groups at 1, 6 and 12 months after operation were lower than those before operation (P < 0.05). Pain VAS score at 1 and 6 months after operation: group A was higher than group B and group C (P < 0.05). Pain VAS score at 1 month after operation: group B was higher than group C. Pain VAS score at 12 months after operation: there was no significant difference among the three groups (P > 0.05). The UCLA shoulder scores of group A at 6 and 12 months after operation and group B and group C at 1, 6 and 12 months after operation were higher than those before operation (P < 0.05). UCLA score at 1 month after operation: group A < group B < group C (P < 0.05). UCLA score at 6 and 12 months after operation: there was no significant difference among the three groups (P > 0.05). The Constant-Murley scores of group A at 6 and 12 months after operation and group B and group C at 1, 6 and 12 months after operation were higher than those before operation (P < 0.05). Constant-Murley score at 1 month after operation: group A was lower than group B and group C (P < 0.05). Constant-Murley score at 6 and 12 months after operation: three groups were equivalent (P > 0.05). Forward flexion and lifting range of motion in the three groups: at 12 months after operation > before operation (P < 0.05). Forward flexion and lifting range of motion was evaluated at 12 months after operation: there was no significant difference among the three groups (P > 0.05). The range of motion of external rotation at body side and external rotation at 90° abduction before operation and at 12 months after operation: there was no significant difference between group A and group B (P > 0.05). External rotation at body side and external rotation at 90° abduction of group C: at 12 months after operation of it was less than that before operation (P < 0.05). The range of motion of external rotation at body side and external rotation at 90° abduction was obtained at 12 months after operation: group A and group B were greater than group C (P < 0.05). Postoperative complication rate and recurrence rate: three groups were equivalent (P > 0.05).Conclusion Conventional open Latarjet surgery, arthroscopic Latarjet surgery, arthroscopic Bankart repair combined with Remplissage surgery can effectively improve shoulder joint function and relieve pain in the treatment of RASD with 15%~25% scapula glenoid bone defect and meshing Hill-Sachs lesion. However, the two shoulder arthroscopic procedures are less traumatic and have faster postoperative recovery.
