Retrospective comparative case-cohort study to investigate the efficacy of the modified arthroscopic Bristow-Latarjet surgery and to compare the clinical and radiographic outcomes using screw fixation vs suture-button fixation.
Background：Some studies have advocated the use of suture-button fixation during Bristow-latarjet surgery to reduce complications associated with screw fixation. However, these studies are not comparative studies, and their data are relatively incomplete. Purpose: To compare the clinical and radiographic outcomes using screw fixation vs suture-button fixation. Study Design: Retrospective comparative case-cohort study Methods: Patients who underwent the modified arthroscopic Bristow-Latarjet surgery between June 2015 and February 2018 were selected. Shoulders were separated into two groups based on surgical fixation method. Radiological results on 3D CT scan and clinical results were assessed preoperatively, immediately after operation, and postoperatively at 3 months, 6 months, 1 year and during the final follow-up.

VAS for pain score
The visual analog scale (VAS) for pain score is the most commonly used to describe pain levels in patients, ranging from 0 to 10, with a higher score indicating more intense pain.
Time frame: 2 years after surgery
ASES score
The American Shoulder and Elbow Surgeons (ASES) score is the most commonly used score to describe the function of patients' shoulder joints, ranging from 0 to 100. The higher the score, the better the function of patients' shoulder joints.
Time frame: 2 years after surgery
Active shoulder ranges of motion
internal rotation at the side, and external and internal rotation at 90° of abduction,
Time frame: 2 years after surgery
Bone block position
Bone block position was evaluated using postoperative CT scans.The ideal position of the bone block was defined as flush to the anterior glenoid rim in the axial view and 4 o'clock in the En face view. The bone block was considered too lateral if it went beyond the glenoid rim by more than 5 mm and it was judged to be too medial if it was medial to the rim by more than 5 mm.
Time frame: immediately after surgery.
Bone union
Graft union with the glenoid was assessed using postoperative CT scans. ''Bony union'' of the transplant was defined as no radiolucent zone; ''fibrous union,'' when the transplant had a radiolucent zone of less than 5 mm; and ''migration,'' when the zone was 5 mm or more.
Time frame: 3 months after surgery, 6 months after surgery, 1 year after surgery and 2 years after surgery
