Twenty-seven previously treated club feet in 25 patients were evaluated retrospectively following tibialis anterior tendon transfer to the dorsum of the foot to correct residual dynamic supination deformity. In 11 feet, the transfer was combined with additional soft tissue and or bony procedures to treat other accompanying deformities. Electrophysiologically demonstrated peroneal weakness causing muscle imbalance contributed to the etiology of this dynamic deformity. At follow-up, none of the patients had dynamic supination deformity during ambulation. All showed active contraction of the transferred tibialis anterior tendon. There was no case of overcorrection. Functional and cosmetic results were assessed by parents and surgeons as being excellent. Tibialis anterior tendon transfer is recommended to correct residual dynamic supination deformity and to restore muscle balance after satisfactory correction of idiopathic club foot contractures.
