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.
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.

Changes in the American Orthopaedic Foot & Ankle Society (AOFAS) scores
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.
Time frame: Before surgery and up to 8 years after surgery
Equinus recurrence rate
The equinus recurrence rate of the patients after surgery is recorded. Lower value represents a better outcome.
Time frame: Up to 8 years after surgery
Infection rate
The infection rate of the patients after surgery is recorded. Lower value represents a better outcome.
Time frame: Up to 8 years after surgery
