Six months postoperatively, magnetic resonance imaging (MRI) revealed a foreign body lodged at the inferior acromion margin, causing acromial cupping, remodeling, and fibrosis. At the 12-month follow-up, the patient presented symmetrical strength and full range of motion with no pain.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>We report the first case of Regeneten implant migration with acromial lodging. Despite MRI findings, the patient remained asymptomatic with no functional limitations. Close postoperative follow-up is essential to monitor complications, even in asymptomatic patients. This case highlights favorable outcomes with conservative management in the presence of implant migration.<\/jats:p>\n
