title: Reconstruction of quadriceps tendon with Achilles tendon allograft in older children with congenital dislocation of the knee.
abstract: This is a case report of two children with congenital dislocation of the knee. They have been treated surgically with Z-lengthening of the quadriceps tendon and additional reconstruction of the quadriceps tendon with Achilles tendon allograft to fill in the remaining average 6 cm gap of the tendon. The patients were two girls, 6 and 9 years old. One of them had an operative treatment previously with a tendon lengthening procedure and it was failed and the other patient was untreated before. Preoperatively, untreated case was unable to walk. The other patient was limping. None of them was able to flex their knees beyond the neutral extension position. Postoperatively, both patients were able to walk and the knees were reduced to a range of motion of 0 degrees -95 degrees of flexion. The mean follow-up time was 20 months.
