Validity and Reliability of Mini-Invasive Surgery Assisted by Ultrasound in Achilles Tendon Rupture

INTRODUCTION: The surgical treatment for Achilles tendon rupture has become very popular in the last years, because of the good outcomes and the low re-rupture rate. AIM: The aim of this study is to compare the results between open surgery and percutaneous ultrasound-assisted surgery. METHODS: All patients who underwent an Achilles tendon surgical repair in the last 3 years were included, resulting in a total of 56 patients (40 M and 16 F) with an average age of 53 years. Of these patients, 36 were treated with an open suture, while 20 with a mini invasive ultrasound assisted suture. At a minimum follow-up of one year, patients were evaluated echografically, using both the Achilles Tendon Rupture Total score (ATRS) and the McComis score, and performing the ultrasounds bilaterally to assess both the structure and the diameter of tendons. RESULTS: Both groups of patients showed an average ATRS score >80. The McComis score was 54.18 vs. 56.25 (p>0.05). Plantar flexion and dorsal flexion work were not similar (p>0.05). On average, the calf circumference of the operated side was decreased compared to the healthy side between the groups (p>0.05). The thickness of the operated tendons evaluated with ultrasound measurement compared to the average tendon, (p <0.05). CONCLUSION: The ultrasound-assisted tenorrhaphy is a reliable treatment with good clinical and functional outcomes; anyway, the percutaneous technique and the open surgery show similar results.
