ABSTRACT

Objective To investigate the clinical effect of the V-Y advancement flap based on double perfo-rators of the posterior tibial artery for reconstruction of small-area tissue defect in the achilles tendon. Methods From June, 2014 to June, 2017, a total of 8 patients with small-area tissue defect in the achilles tendon were repaired by the V-Y advancement flap based on double perforators of the posterior tibial artery. The size of defects ranged from 1.5 cm ×3.5 cm to 3.5 cm ×5.0 cm, and the size of flaps ranged from 2.0 cm ×8.0 cm to 4.0 cm ×12.0 cm. The donor area was directly sutured. Eight cases were followed-up, and the appearance, quality, color and elasticity was raorded. Results All V-Y advancement flaps based on double perforators of the posterior tibial artery survived, and all donor sites were directly sutured. Followed-up for 3 to 12 months. All V-Y advancement flaps were flat with the sur-rounding tissue. The appearance, quality, color and elasticity of flaps were good. According to the related evaluation criteria made by the American Orthopedic Foot and Ankle Surgery Society (AOFAS), the results of 8 patients were ex-cellent in 6 cases, and good in 2 cases. The patients had a high degree of satisfaction. Conclusion Application of the V-Y advancement flap based on the double perforators of the posterior tibial artery is an ideal method to repair the small-area tissue defect in the achilles tendon. This kind of surgery is simple, safe and has minimal donor site mor-bidity.
