Objective To evaluate the mechanical property of a new parachute-like and through-calcaneus suture combination technique for the repair of Achilles tendon rupture. Methods Eight Achilles tendons each respectively from eight New Zealand white rabbits were repaired by a new suture technique which combined the end-to-end suture method with 0/0 Poliglactin-910 and the cross-stitch epitenon suture method with 5/0 Poliglactin-910. After the suture, the rabbits were given 3-day immobilization cast and then 25 days of functional practice. The in vitro experimental study was conducted next. Results The experimental group achieved 90% of the biomechanical property of the intact group. Conclusion The tendon repair of the new combinatory technique allows early-mobilization which in turn improves the mechanical property of the repaired Achilles tendons.
