L’ostéochondrite disséquante du genou chez l’enfant et l’adolescent. Notre expérience à propos de 32 cas

Osteochondritis dissecans (OCD) rarely involves the femoral condyle and affects especially the athletes. Etiology of OCD remains enigmatic. This retrospective study analyzed 32 cases (28 children) stemming from a paediatric series. All the concerned children exercised a sports activity. OCD can be grave on the functional plan and burden the sports future of the child. The clinical symptomatology was poor. The circumstances of discovery were essentially represented by an atypical pain of the knee. The diagnosis was confirmed by a standard radiography revealing a specific hurt of variable aspect, being able to go of a simple suspect line to a big loss of substance at the level of the femoral condyles. The used classifications were the ones of Bedouelle, Cahill, as well as Harding one. Mostly, the pathology was diagnosed at a premature stage I and II of Bedouelle. The examinations of imaging (Magnetic Resonance Imaging MRI], CT scan) were individually decided to explore the lesion or for a choice of the therapeutics. The stake in simple discharge with a strict stop of the sport gave satisfactory results so clinical as radiological in our study. The surgery was exceptional. The forecast is usually good at the child's subject to an adapted coverage by not allowing passing the hour of the surgery. The sport practised in an excessive, intense way (competitive sport) is recognized as a major risk factor.
