Kim, Gwak, Lee, Kim, and Jeong: A Comparative Study of Surgical Treatment Result in the Ruptured Achilles Tendon: Minimal Incision Percutaneous Repair and Open Repair

Abstract

Purpose

To compare and analyse the clinical outcomes between minimal-incision percutaneous repair and open repair among the surgical treatments for Achilles tendon ruptures.

Materials and Methods

We retrospectively analyzed and compared the outcomes between 25 patients with minimal incision percutaneous repair (group 1) and 30 patients with open repair (group 2), from January 2006 to June 2014. The postoperative clinical evaluations were done by Arner-Lindholm scale, American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, overall patient's satisfaction, and cosmetic satisfaction of scar.

Results

There were statistically significant differences between the two groups with respect to AOFAS hind foot score, mid-calf circumference differences, overall patient's satisfaction, and satisfaction of scar; the group 1 showed better achievement. There was no statistical difference between two groups in regards to other clinical outcomes. In group 1, there were 2 cases of sural nerve hypoesthesia, which fully recovered spontaneously at about 6 months after the surgery. In group 2, there were 3 cases of deep vein thrombosis, re-rupture, and deep infection.

Conclusion

We recommend minimal incision percutaneous repair as one of the effective surgical treatment options for Achilles tendon ruptures.
