Excision of the posterior tibial tendon during clubfoot release.

In 50 patients (72 clubfeet), the posterior tibial tendon was excised during complete soft tissue clubfoot release. The end results after an average of 3 years were graded as follows: 55.5% excellent, 29.3% good, 8.3% fair, and 6.9% poor. Heel varus and forefoot adduction were the main causes for recurrence. Heel valgus occurred in one foot. Excision of the posterior tibial tendon is safe, does not lead to overcorrection, and may prevent further scarring created when the tendon is lengthened.
