Poster 165: Non-Rigid Fixation Results in Higher Failure Rates Following Arthroscopic Glenoid Reconstruction

Objectives: It has previously been established that screw fixation results in better outcomes than button for arthroscopic anatomic glenoid reconstruction (AAGR) with frozen allograft. There considerable debate on the causes higher dislocation rates non-rigid fixation. The purpose of this study was to evaluate which factors may affect failure AAGR Methods: This a retrospective review patients who had using were age-, gender-, and followup-matched patients. Arthroscopic videos used surgical including graft placement, quality, tensioning, contact, soft tissue quality repair, presence Hill-Sachs, addition Remplissage. Patient demographic (age, gender, medical history etc) also assessed. XRays CTs union, angle, remodeling, pull through. Results: A total 36 included our between 2014 2019 (18 matched 18 fixation). Seven requiring reoperation. Of these, 4/7 poor anterior tissue. All but one patient excellent repair balance at end surgery. seven complete resorption compared those did not fail normal post-operative A-P dimension. Conclusions: In case series, high rate recurrent dislocation. These failed appropriate equivalent dislocated successful correlated technique, or radiographic rather only type. Further is needed methods assess whether type impacts these clinical outcomes.
