Osteochondral autograft transplantation of the femoral head in sequelae of developmental dysplasia of hip: A case report and review of the literature.

Although osteochondral autograft transplantation (OAT) in the knee and ankle has gained much popularity on the other hand the technique has rarely been applied in the femoral head. In this article, we present a 15-year-old female patient with unstable chondral lesion on the right femoral head. She had a history of open reduction for developmental dysplasia which resulted in avascular necrosis. She had coxa magna, breva and trochanteric overgrowth along with an unstable chondral lesion on the superolateral part of the femoral head. She underwent OAT for chondral lesion, femoral head reshaping and relative neck lengthening. Her Harris Hip Score improved from 55 to 90 in the 18 months of follow-up. The case is unique in a way that the autografts were harvested from the anterior part of the same femoral head that was already intended to be removed during osteochondroplasty.
