Management of Chronic Achilles Tendon Rupture with Tibialis Anterior Allograft: A 2-Year Follow-up Study.

Introduction: Chronic Achilles tendon ruptures are challenging to manage, particularly in older patients. This report describes the surgical repair of a chronic rupture using a tibialis anterior allograft in a 61-year-old male, emphasizing the technique and outcomes of this approach.

Case report: A 60-year-old male with a 3-month-old Achilles tendon rupture presented with difficulty in walking, pain, and functional impairment. Imaging revealed a 2 cm gap. Surgical management included debridement and reconstruction using a tibialis anterior allograft anchored transversally through the calcaneus. At 2 years postoperatively, the patient had a full ankle range of motion, pain-free ambulation, and restored functionality.

Conclusion: Tibialis anterior allograft is a viable option for reconstructing chronic Achilles tendon ruptures with smaller gaps in older patients. It offers reliable functional recovery while minimizing the morbidity associated with autografts.
