Old achilles tendon rupture accompanied by skin defect was a common amp; annoying problem in clinic. From June, 1985 to June, 1996, 18 cases with this kind of injury were treated by one stage repair of the tendon and skin defect. In this series, there were 15 males and 3 females, the length of tendon defects were ranged from 4 cm-6.1 cm, and the area of skin defect were ranged from 5.9 cm x 3 cm to 8.2 cm x 6 cm. The procedures were: (1) to debridement of the wound thoroughly; (2) to repair the achilles tendon; (3) to repair the skin defect with kinds of pedicle flap; (4) immobilization of ankle and knee for 6 weeks. No infection was occured after the operation. The flaps survived in all cases. After follow-up for one year in 15 cases, 12 patients went back to their work. It was concluded that (1) achilles tendon rupture should be treated carefully and properly during the emergency operation; (2) different methods should be selected according to the length of tendon defect; (3) because of its high survival and retained sensation after operation, the flap pedicled with posterior lateral malleolar artery is the best choice for repairing the skin defect.
