A Study on the Treatment of Recurrent Clubfoot With the Tendon Release of Musculi Tibialis Posterior

Study Overview
=================
Brief Summary
-----------------
The musculi tibialis posterior can adduct the foot, so releasing the tedon of the muscle can help to correct the deformity of the forefoot adduction.

Official Title
-----------------
A Multicenter Study on the Treatment of Recurrent Clubfoot With the Tendon Release of Musculi Tibialis Posterior

Conditions
-----------------
Recurrent Clubfoot

Intervention / Treatment
-----------------
* Procedure: The tendon release of musculi tibialis posterior
* Procedure: Anterior tibial tendon transfer(TATT)
