In management of foot deformity, the operative procedures such as tendon transplantation and bone stabilization are of the relatively recent origin. The first tendon transfer was performed by Nicoladoni in 1881. Since that original report, a voluminous literature was appeared on the subject of tendon trasplantation. During the period, from Jan. 1960 to May. 1992, we have done clinical studies of the 189 feet on 167 patients who had been undergone tendon transfer. The results are as followes, 1. Residual poliomyelitis, leprosy, cerebral palsy and club foot are common etiology. Among them, residual poliomyelitis was the most common, especially in 1960 to 1969. Recently trauma and aged leprosy were increased. 2. Among 189 feet, the equinovaurs deformities were 90 cases. 3. Posterior tibial tendon, peroneus tendons, anterior tibial tendon, Achilles tendon and extensor hallucis tendon were transferred. 4. Posterior tibial tendon was mostly used. 5. The evaluation for surgery, for Good to Excellent was 114 feet 60. 3% 6. The poor results were noticed in the cases of the calcaneal deformity and showed in the age below 5 years old.
