Osteochondritis dissecans patellae - Is there a genetic predisposition?

Abstract

The aetiology of Osteochondritis Dissecans Patellae remains controversial. We present a family suffering from the condition in all members of one generation. Clinical data support the hypothesis that the aetiology of the disorder in this family is recurrent subluxation of the patella, the inherited predisposing factor being an abnormality of the mechanics of the knee. © 1992 Springer-Verlag.
