Abstract

Congenital dislocation of the patella is a rare clinical entity and is considered to result from a failure in internal rotation when the myotome develops, which forms the femur, the quadriceps muscle, and the extensor mechanism. Several authors have suggested various treatment methods, but there has been no consensus on treatment. A 12-year-old boy complained of knee pain and presented with a deformity due to bilateral congenital dislocation of the patella. The patient was treated with surgical management using the Stanisavljevic procedure. We report this case of congenital dislocation of the patella treated with this procedure that achieved a stable patellofemoral joint and satisfactory clinical results over 6.5 years of follow-up. In addition, we have included a review of the relevant medical literature.

Figures and Tables

Figure 1

Clinical photograph of a 12-year-old boy with bilateral congenital dislocation of the patella. (A) Patellae are maintained at anatomical position in knee flexion. (B) Patellae are dislocated laterally in knee extension.

Figure 2

The initial anteroposterior radiographs of both knee. (A) The right patella is dislocated laterally, and presented genu valgus with external tibial rotation. (B) The left patella is dislocated laterally, but no genu valgus and external tibial rotation are seen.

Figure 3

Quadriceps muscle is medially rotated by subperiosteal dissection (black arrows). Patellar tendon divided longitudinally, and lateral portion was transferred medially (white arrow). Lateral defect area was covered by the fascia lata (arrow head).

Figure 4

The follow-up radiograph taken 4 years after 1st operation shows a properly located right patella in the trochlea groove, but the left patella is dislocated laterally on the Merchant view.

Figure 5

The follow-up radiograph taken 6.5 years after the 1st operation (2.5 years after 2nd operation) shows a developed trochlear groove and a well located patella on the Merchant view.
