Outcomes of anatomic total shoulder arthroplasty: evaluation of implant-related, radiographic, and demographic factors influencing durability and revision rates.

Purpose: To evaluate the impact of implant-associated and radiographic factors on survival rates and revisions of total shoulder arthroplasty (TSA) in patients with primary osteoarthritis (OA).

Methods: This retrospective study included 68 patients who underwent TSA for primary OA at a single institution between 2008 and 2015, with a minimum follow-up of 60 months. Patients with prior shoulder surgeries, perioperative infections, or revisions within 12 months postoperatively were excluded.
