Objective    To evaluate the clinical effect of Achillon

®

minimally invasive Achilles tendon suture system on repairing acute closed Achilles tendon ruptures through 2-cm-long incision.     Methods    Twenty-nine patients with acute closed Achilles tendon ruptures were treated with Achillon

®

minimally invasive Achilles tendon suture system

and the clinical effect was evaluated by follow-ups. Based on the results of presurgical physical examination and MRI

the rupture parts of Achilles tendons were located. The rupture end of each rupture part was exposed through 2-cm-long incision

and Achi

llon

®

minimally invasive Achilles tendon suture system was put in to hold the proximal rupture end of Achilles tendon. Then suture threads were introduced to both proximal and distal rupture ends

pulled out and knotted together. The ankle was cast with gypsum for 6 weeks after surgery.     Results    Two out of twenty-nine patients underwent minimally invasive Bunnell suture during surgery as the rupture parts of Achilles tendons were like horsetails. Twenty-six cases were successfully followed-up for 14 to 48 months (average 23 months)

and Arner-Lindholm score showed that the surgical results were perfect for 23 cases (88.5%) and good for 3 cases (11.5%). The patients did not suffer infection or Achilles tendon malunion.     Conclusion    Repair of acute closed Achilles tendon ruptures with Achillon

®

minimally invasive Achilles tendon suture system through 2-cm-long incision is reliable in wound healing with few

if any

invasions to skin. The risk of skin injury

re-rupture and infection is low

and the ankle function recovery is fast. Therefore

Achillon

®

minimally invasive Achilles tendon suture system is a good choice to repair acute closed Achilles tendon ruptures.
