简要总结
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.
详细描述
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.

结局指标
主要结局
Changes in the American Orthopaedic Foot & Ankle Society (AOFAS) scores
时间窗: Before surgery and up to 8 years after surgery
The AOFAS scores of the patients before and after surgery are recorded. The scale ranges from 0-100 points, and increases of the value represent a better outcome.
次要结局
- Equinus recurrence rate(Up to 8 years after surgery)
- Infection rate(Up to 8 years after surgery)
