Acromial Cupping with Lodged Bioinductive Collagen Implant Following Rotator Cuff Repair: A Case Report.

CASE: We report a 39-year-old man with a supraspinatus retear treated with a Regeneten implant. 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.

CONCLUSION

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.
