To date, there is no consensus concerning the treatment of acute Achilles tendon ruptures. Although surgical treatment decreases the risk of a recurrent rupture, it is not without complications. In particular, percutaneous sutures may cause a lesion of the sural nerve. The purpose of this Technical Note is to describe a reliable and reproducible surgical procedure for treating these lesions. The first operative phase consists of an ultrasound detection that makes it possible to identify the tendon extremities and the sural nerve, which is necessary to secure the posterolateral arthroscopic tract as well as to perform the percutaneous suture. The entry point is thus centered on the lesion and placed at a distance from any surrounding nerve risk. The second arthroscopic phase makes it possible to release the tendon lesion, control the transtendon passage of the surgical threads, and evaluate the dynamic contact of the tendon edges. At the end of the intervention, the complete disappearance from the transillumination via the rupture also makes it possible to ensure the disappearance of the tendon gap. Achilles tendon percutaneous sutures after the ultrasound detection and under arthroscopic control thus makes it possible to control the contact of the tendon edges, while at the same time decreasing the risk of a lesion of the sural nerve, with minimal scarring.
