Video Summary

Rakesh John presented a study on arthroscopic anatomic glenoid reconstruction (AAGR) using distal tibial allografts for glenoid bone loss in shoulder instability, with a minimum two-year follow-up. This technique preserves the subscapularis and neurovascular structures by using a specialized Halifax portal, offering anatomic reconstruction without subscapularis splitting. In 66 patients (mean age 29.7), AAGR showed 100% graft union, improved clinical scores, and no re-dislocations or nerve injuries. Graft resorption occurred in some but did not compromise stability. Compared to Latarjet, AAGR is safer, less invasive, and spares anatomy for future revisions. Longer-term studies are needed.
