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.展开更多

Therefore, the aim of this study was to investigate the effects of patellar and hamstring tendon grafts on long-term knee function after anterior cruciate ligament reconstruction. Methods This meta-analysis was conducted according to the methodological guidelines outlined by the Cochrane Collaboration. An electronic search of the literature was performed and all trials published between January 1966 and August 2011 comparing knee function after anterior cruciate ligament reconstruction using patellar tendon grafts with knee function after reconstruction with hamstring tendon grafts were pooled. Six studies were included in the final meta-analysis. Results Anterior cruciate ligament reconstruction using hamstring tendon grafts resulted in greater pain upon kneeling than reconstruction using patellar tendon grafts （P=0.001）. However, both grafts resulted in similar levels of anterior tibial translation, and similar results regarding isokinetic extension/flexion tests, Lysholm scores, and the stair-hop test （P 〉0.05）. Conclusion Anterior cruciate ligament reconstruction using patellar or hamstring tendon grafts results in similar long-term knee function.展开更多
