Abstract:

Objective　To evaluate clinical effects of osteocutaneous flap of adductor magnus tendon pedicled with descending genicular artery on repair of Achilles tendon composite defect.　Methods　Osteocutaneous flap of adductor magnus tendon pedicled with descending genicular artery were individually designed and surgically used on 3 cases with traumatic Achilles tendon defects, combined with soft tissue and calcaneal bone damage. The area of skin defect was ranged from 7 cm×9 cm to 5 cm×7 cm, and the length of Achilles tendon defect was 6 ~ 8 cm. During the operation , the flaps was designed as 8cm×10cm to 6cm× 8cm, with the cutting length of the adductor magnus tendon 7~ 9 cm . Results: All 3 cases were followed-up for 6 to 12 months. The transplanted tissue flap survived well. The texture, appearance and function of the flap were excellent.　Conclusions　It is a ideal way to repair of Achilles tendon composite defect, using osteocutaneous flap of adductor magnus tendon pedicled with descending genicular artery, which avoiding the severe surgical trauma and the extended isolation of vessels.
