Percutaneous and minimally invasive techniques of Achilles tendon ruptures

Despite the controversy regarding the best treatment for an acute Achilles tendon rupture, percutaneous and minimally invasive techniques seem to offer good results in terms of low risks of rerupture and complications with satisfactory clinical and functional outcomes. A comparison between a percutaneous surgical technique and a minimally invasive one has not been reported in the literature. We consecutively evaluated 12 patients who had a modified Ma and Griffith percutaneous Achilles tendon repair and 12 patients who had a minimally invasive technique. The same semifunctional rehabilitation protocol was used after surgery in both groups. At a minimum followup of 24 months (mean, 33 months; range, 24-42 months), we observed no reruptures or major complications in either group. Both groups had similarly high values for the American Orthopaedic Foot and Ankle Society score. The two techniques allowed equivalent time for return to work and sports. In the group of patients treated with the modified Ma and Griffith suture only, the mean loss of calf circumference in the injured leg was greater, compared with the contralateral leg. The two groups were isokinetically similar. In this study, the percutaneous and minimally invasive techniques of repair of the Achilles tendon yielded essentially identical clinical and functional outcomes
