Brief Summary

This study aims to evaluate the efficacy and safety of this new therapeutic method, which is based on the percutaneous sliding technique with three hemi-cuts in the tendon.

Detailed Description

This study aims to provide a new therapeutic theory which bases on the percutaneous sliding technique with three hemi-cuts in the tendon. In this study, Achilles tendon parenchymal at distal level is hemisected through the most distal incision, Achilles tendon parenchymal at proximal level is hemisected through the middle incision, then Achilles tendon lengthening is accomplished by the sliding tendon under forceful dorsiflexion. It can better achieve soft tissue balance and reduce the recurrence of Achilles tendon contracture when Achilles tendon strength in plantarflexion is weakened. Thus in this study, the partial aponeurosis of gastrocnemius is cut off at most proximal incision in order to weaken Achilles tendon strength in plantarflexion.
