Screw Fixation has Better Outcomes, Lower Incidence of Re-dislocation and Lower Bone Resorption than Button Fixation for Arthroscopic Anatomic Glenoid Reconstruction with Distal Tibia Allograft: A Matched Cohort Analysis.

Purpose: To compare the clinical outcomes between patients who received arthroscopic anatomic glenoid reconstruction (AAGR) using distal tibia allograft with button fixation versus screw fixation.

Methods: A retrospective chart review was conducted for all patients who underwent AAGR with button or screw fixation between 2012 and 2021. Patients were matched at a 1:1 ratio based on sex, type of surgery, and time since surgery.
