Objective To find out a new vascularized donor tendon for grafting. Methods A detailed anatomical study olplantaris tendon and its vascular connection with the posterior tibial artery was carried out in 16 legs of 8 fresh adult cadavers, and histological examination of the vascular pattern was also performed. Results There exists a close vascular connection between the crural las cial - linked part of the plantaris tendon and the posterior tibial artery. The blood supply of the plantaris tendon is provided by 2~4 transfasctal branches of the posterior tibial artery in the lower- middle part of leg. Out of these branches, one or two anastomosable arteries (more than 1.0cm) together with veins constantly emerge 5~8cm from the insertion of the plantaris tendon. A strip of Achilles tendon can be a substitute in case of plantaris missing tendon. The histotwical observation demonstrates the reliable vascularity of the paratenon and crural fascial. Conclusion The plantaris tendon is a better option of donor vascularized tendon. A composite tendofascial flap with vascularized pedicle from the posterior tibial artery or its branches is supposed to be an advisable method for vascularized tendon gralt clinically. In the case of the plantaris missing, a strip of Achilles tendon should be the second choice.
