Eligibility

Sex/Gender

All

Inclusion criteria

Inclusion criteria: Adults aged 19 years or older with chronic anterior shoulder instability scheduled for surgical treatment (complaining of ipsilateral shoulder pain or instability, with a positive Apprehension test on physical examination) History of at least two complete dislocations of the ipsilateral shoulder Preoperative CT demonstrating anterior glenoid bone loss =20% as measured by the Best-fit circle method (external imaging accepted; investigator may determine the need for repeat imaging based on history and findings)

Exclusion criteria

Exclusion criteria: Voluntary dislocators Pregnant or breastfeeding women Irreparable massive rotator cuff tears (Cofield classification >5cm, Patte stage 3, Goutallier grade =3) Prior surgery on the ipsilateral shoulder for indications other than anterior instability (e.g., infection, fracture) Patients with advanced glenohumeral osteoarthritis (OA, Grade =3 by Samilson and Pietro) or rheumatoid arthritis Uncontrolled seizures, infectious diseases affecting the shoulder, autoimmune or systemic musculoskeletal disorders Cases where a Bony Bankart lesion alone is expected to reduce glenoid bone loss to <20% by arthroscopic surgery Patients with a Hill-Sachs interval (HSI) exceeding the normal glenoid width (D) Patients deemed by the investigator to have insufficient shoulder stability despite surgery Patients who may gain secondary benefits by participating in the trial Patients unwilling to voluntarily participate Other cases deemed unsuitable by the principal investigator (e.g., impaired consent capacity, emotional or socioeconomic reasons)
