Evaluation of a Modified Spoon-Shaped Medial Incision in the Surgical Repair of a Chronic Achilles Tendon Rupture

Abstract This study aims to investigate the clinical significance of preventing incision skin necrosis and the improved function offered in patients with a chronic Achilles tendon rupture treated surgically with a modified spoon-shaped medial incision. From January 2013 to January 2017, 50 patients (N = 50) who were admitted to our department with a clinically and radiologically confirmed chronic Achilles tendon rupture met inclusion criteria and were divided retrospectively into two groups. In group A (n = 26), a modified spoon-shaped medial incision in the surgical repair of Achilles tendon rupture was performed. In group B (n = 24), a traditional posterior medial incision was used. All skin healing was observed. Functional evaluation was performed using American Orthopedic Ankle & Foot Society scale(AOFAS) hindfoot score and Achilles tendon total rupture score(ATRS). Return-to-work time and major complications were also measured. The patients were followed for 12 to 48 months. All incisions exhibited primary healing in group A, while four incisions healed delay for skin necrosis which includes superficial, deeper necrosis, and skin defection caused by the necrosis in group B. Both groups had similar results regarding return-to-work time. There were no infections in either group. There was no rerupture of the Achilles tendon in either group. Patients in group A had better AOFAS hindfoot score (p = .020) and ATRS (p = .010), and the difference was significant (p ≤ .05).Using the modified spoon-shaped medial incision in the surgical repair of a chronic Achilles tendon rupture seems to be a safe and effective method that may reduce risk of incision skin necrosis and offers better function in patients with a chronic Achilles tendon rupture.
