Adult acquired flatfoot

and tibialis posterior tendonopathy

Cobb procedure

Another tendon transfer method was described by Cobb and popularised in the southern UK and some other circles by Helal. The tibialis anterior tendon was split, passed through the medial cuneiform or the tibialis posterior insertion, then through the tibialis posterior sheath and attached to the tibialis posterior stump proximally. This gave a large, strong reconstruction which seemed more able to restore the arch.
