Treatment of a Damaged Posterior Tibialis Tendon Through Reconstruction Using a Hamstring Autograft.

This case report presents the unique clinical history of a 26-year-old male patient who experienced a posterior tibial tendon (PTT) rupture following the Kidner procedure for a symptomatic accessory navicular bone. The subsequent reconstruction utilized a hamstring autograft. The patient, unresponsive to conservative treatments, underwent the Kidner procedure, resulting in PTT rupture at the eleventh postoperative week. Surgical intervention involved hamstring autograft retrieval, creating a bone tunnel in the navicular, and securing the autograft to the proximal PTT stump along with an Evans procedure. The case contributes to the discourse on PTT reconstruction methods, emphasizing the distinctive choice of autograft, specifically the hamstring, and its efficacy. At the 28-month follow-up, the patient did not complain of any residual pain and he was able to perform normal daily activities without any limitations. This case sheds light on PTT complications after the Kidner procedure, and emphasizes the role of autograft reconstruction, while contributing to the ongoing discussions about optimal strategies.
