Clinical and Radiographic Outcomes in Arthroscopic "Inlay"Bristow Surgery With Screw Fixation vs Suture-button Fixation

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.

Inclusion Criteria:

1. a glenoid defect ≥10%
2. contact sport athletes with a glenoid defect < 10%
3. failure after Bankart repair.

Exclusion Criteria:

1. epilepsy
2. multidirectional shoulder instability
3. concomitant other lesions including rotator cuff tear, symptomatic acromioclavicular joint pathology or pathological involvement of the long head of the biceps
4. Follow-up was less than 2 years or incomplete follow-up data.
