Outcome of Percutaneous Fixation of Acute Achilles Tendon Ruptures.

Background: Conservative treatment of an acute Achilles rupture remains a viable and acceptable option as does surgical fixation, with open and percutaneous repair consisting the main operative techniques. The purpose of this study was to compare the outcomes and complication rates of open versus percutaneous surgical procedures. Methods: From 2009 to 2016, 131 patients were admitted to our department with clinically and radiologically confirmed acute Achilles tendon ruptures. Of those, 82 patients met our inclusion criteria and were randomized into 2 groups, group A (open repair) and group B (percutaneous suturing). Suture equipment was the same for both groups. All patients followed the same rehabilitation protocol. Functional evaluation was made using American Orthopaedic Ankle & Foot Society (AOFAS) hindfoot and Achilles tendon Total Rupture Score (ATRS) questionnaires at the 12-month follow-up. Ankle range of motion (ROM), return-to-work time, and complication rates were additionally measured. Results: Both techniques had similar results regarding complication rates and return-to-work time. The major complication in group A was superficial infection (7%) and skin necrosis (3%), whereas 3 patients in group B developed paresthesias due to sural nerve entrapment. Patients in group B had better AOFAS hindfoot (96/100) and ATRS (95/100) scores, but the difference was not significant. ROM was similar in both groups at the 12-month follow-up. Conclusion: Percutaneous suturing seems to be a safe and effective technique that offers good functional outcomes and low complication rates in patients with acute Achilles tendon ruptures who elect to have surgery. Level of Evidence: Level II, prospective case series.
