Open vs. Percutaneous Achilles Tendon Repair: Experience of Single Orthopedic Institute with Long-Term Follow-Up.

: There are numerous techniques for the surgical treatment of Achilles tendon lesions described in the literature, and it is possible to distinguish repair techniques as either open surgery or percutaneous repair techniques. Both approaches have advantages and disadvantages. With this retrospective study, we aim to analyze the incidence of re-ruptures and other complications, return to sport and overall quality of life at a long-term follow-up in the treatment of acute ATRs, comparing the results of percutaneous repair with those of open repair. : This is a retrospective study on a consecutive series of patients with complete tear of the AT who were managed through a surgical approach by the Operative Unit of Orthopaedics and Traumatology of Sant'Anna University Hospital (Ferrara, Emilia-Romagna, Italy) between April 2014 and December 2021. Patients were treated with a percutaneous or an open technique according to the surgeon's preference without randomization. : We considered 155 patients who met the established inclusion criteria. Of these, 103 (66.45%) patients underwent percutaneous treatment with the Tenolig system, and 52 (33.55%) underwent open surgery, with an average ATRS in the first group of 92.5 compared to an average ATRS value of 82 in patients treated with the open technique. : In our experience, following overlapping rehabilitation protocols in all patients included, we observed that the Tenolig repair system led to a better ATRS at long-term follow-up, with comparable complication rates to open surgery.
