Recurrent dislocation of the patella is a relatively uncommon disease, which is most commonly seen in late adolescence. The condition is usually spontaneous and only rarely follows traumatic dislocation. But congenital anomalies such as cerebral
palsy,
myelodysplasia, arthrogryposis, lateral femoral condyle aplasia, congenital dislocation of the hip, Down syndrome accompany this condition infrequently. The surgery is the treatmetn of choice for recurrent dislocation of the patella. But, no one
type of
operation can be useful for all recurrent dislocation of the patellay, especially in children. A case of the recurrent dislocation of the patella observed in 13 year old boy with Down syndrome, in which the authors performed the semitendinosus
tenodesis.
Postoperative result was good no term of range of motion and no recurrence.
