Objectives: Despite a growing body of literature regarding optimal repair configurations, little is known about inferior suture anchor placement (6 o’clock position). Here, we determine the biomechanical strength of adding a 6’oclock anchor to a “standard” Bankart repair in a normal glenoid and a 13% anterior bone loss model. Methods: 12 cadaveric shoulders were tested on a six axis industrial robot to measure the peak resistance to translation force with anterior displacement (1 centimeter). The rotator cuff muscles were loaded during testing to simulate physiological conditions. Test conditions included intact shoulder, Bankart lesion, Bankart repair (3, 4, and 5 o’clock anchors), and Bankart repair with a 6 o’clock anchor. A 13% anterior bone defect was then created (based on pretest CT scan) and all conditions were repeated. Repeated measures ANOVA was used to test for significant differences among groups. Results: In the no bone loss group, the addition of a 6 o’clock anchor yielded the highest peak resistance force (52.8 N, SD: 4.5 N) and was significantly stronger than the standard Bankart repair by 15.8% (7.2 N, p = 0.003). With 13% bone loss from the anterior glenoid, both the standard Bankart repair (peak force 49.3 N, SD: 6.1 N, p = 0.02) and repair with the addition of the 6 o’clock anchor (peak force 52.6 N, SD: 6.1 N, p = 0.006) had a significantly higher peak resistance force compared to the bone loss with Bankart lesion group (35.2 N, SD: 5.8 N). While the 6 o’clock anchor did increase the strength of the standard repair by 6.7%, this was not statistically significant (p = 0.9) in the bone loss model. Conclusion: The addition of a 6 o’clock suture anchor to a ”standard” Bankart repair increases to the peak resistance to translation force (no bone loss), although this additional strength is lost with creation of a 13% anterior glenoid bone defect.

Background: Open Bankart repair provides surgeons and patients with an alternative solution for managing recurrent instability in young athletes with or without minimal bone loss. Despite many studies that have reported low recurrence rates and good functional outcomes after open Bankart repair, we have limited knowledge about the return to sport and work for high-demand populations. Purpose: To assess the return to sport and work for high-demand populations after open Bankart repair for recurrent anterior shoulder instability, outcomes of open Bankart repair with regard to recurrence, and development of osteoarthritic (OA) changes. Study Design: Systematic review; Level of evidence, 4. Methods: We searched PubMed, EMBASE, Cochrane Library, Scopus, and Google Scholar databases using keywords as well as Medical Subject Headings terms and Emtree using “(Open Bankart OR Bankart surgery) (NOT arthroscopy NOT revision)” for English-language studies. We conducted a systematic review in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Results: In total, 11 articles (10 with level 4 and 1 with level 3 evidence) including 563 patients (566 shoulders) were identified. The majority of patients were male (82%), the average age at the time of surgery was 27.4 years, and the mean follow-up was 11.5 years (range, 2.5-29 years). The most common functional score used was the Rowe score (95%) for the reported outcome measures, which showed good to excellent results (mean, 88.5 points). The overall recurrent instability rate, including dislocation and subluxation as a postoperative complication, was 8.5%. A total of 87% of patients were able to return to sport and work postoperatively. Overall, OA changes were reported in 33% of the patients, and the overall revision rate was 1%. Conclusion: Open Bankart repair exhibited favorable results, with a low postoperative instability rate. It is a reliable surgical procedure that allows high-demand patients to return to sport and work.

Objectives A new concept of dynamic anterior shoulder stabilization (DAS) combining Bankart repair with the additional sling effect of the long head of the biceps (LHB) tendon to treat anterior glenohumeral instability has recently been introduced. The purpose of this study was to biomechanically investigate the stabilizing effect of the DAS technique in comparison to standard Bankart repair in different defect models. Methods Twenty-four fresh frozen cadaver shoulders (average ± SD: age 60.1 ± 8.6 years) were mounted in a shoulder-testing system allowing 6 degrees of freedom. According to cross sectional area ratios the rotator cuff muscles and the LHB tendon were loaded with 40 N and 10 N, respectively. Glenohumeral translation was tested in 60° abduction and 60° external rotation (ABER position) while forces of 20 N, 30 N and 40 N were applied. The translation was measured using a 3D-digitizer and the total translation and the relative translation in relation to the native starting position were determined. Maximal external and internal rotation after application of 1.5 Nm torque to the humerus were measured. All specimens went through for 4 different conditions (Intact, defect, isolated Bankart repair, DAS) and were randomized to 3 different defect groups (Isolated Bankart lesion; 10% anterior glenoid defect; 20% anterior glenoid defect). Results Both surgical techniques resulted in decreased anterior glenohumeral translation in comparison to the defect conditions in all defect groups. In comparison with isolated Bankart repair DAS showed significant less relative anterior translation in 10% glenoid defects (30 N: 2.6 ± 3.4 mm vs. 5.3 ± 4.2 mm; p=0.044) and in 20% glenoid defects (40 N: 2.1 ± 6.6 mm vs. 6.0 ± 5.7 mm; p=0.035). However, in 20% defects DAS led to a relevant posterior and inferior shift of the humeral head in ABER position and to a relevant increase of inferior glenohumeral translation. Both surgical techniques did not limit the rotational range of motion. Conclusion In the context of minor glenoid bone defects the DAS technique demonstrates superior results in comparison to isolated Bankart repair.
