Bilateral congenital dislocation of the patella associated with synostosis of proximal tibiofibular and proximal radioulnar joints: A case report.

Congenital dislocation of the patella is a rare and difficult pathology to treat. We present a case of bilateral congenital dislocation of the patella with synostosis of proximal tibiofibular and proximal radioulnar joints without genu valgum deformity of both knees in a 30-year-old man. To our knowledge, congenital dislocation of the patella associated with synostosis of proximal tibiofibular and proximal radioulnar joints has not been reported in the literature yet
