BACKGROUND Recent data suggest magnetic resonance imaging (MRI) is the best method to analyze the status of the cartilage and subchondral bone in patients with juvenile osteochondritis dissecans (JOCD). METHODS MRI analysis of 122 knees and 132 JOCD lesions in 109 patients who underwent arthroscopic treatment for osteochondritis dissecans lesions of the knee between March 2003 and January 201...

Of ninety-five patients with corticosteroid-induced avascular necrosis of bone, ninety-one had involvement of the femoral head. The risk of developing this lesion appeared to be correlated with the total steroid dose. Forty-nine patients demonstrated a subchondral osteolytic defect which healed without proceeding to collapse. Four femoral heads in four patients developed sequestration, resembli...

The term osteochondritis dissecans is used in this paper to describe an apparently non-infective condition in which a portion of articular cartilage and underlying bone is slowly separated from its bed. The separation, which is at first partial, may be completed with the formation of one or more loose bodies. It is commonly believed that the incidence of osteochondritis dissecans in the knee is...

INTRODUCTION Osteochondritis dissecans (OCD) of the femoral condyle is a rare lesion. MATERIALS AND METHODS A retrospective study (level IV evidence) analyzing a series of 40 pediatric cases with juvenile femoral condyles osteochondritis treated by arthroscopic multiple transchondral drilling between February 1999 and June 2008 was undertaken. This lesion affected the medial condyle in 87.5% ...

Osteochondritis dissecans (OCD) of the capitellum is an uncommon disorder seen primarily in the adolescent overhead athlete. Unlike Panner disease, a self-limiting condition of the immature capitellum, OCD is multifactorial and likely results from microtrauma in the setting of cartilage mismatch and vascular susceptibility. The natural history of OCD is poorly understood, and degenerative joint...

Osteochondritis dissecans is a condition affecting a joint in which a variably sized wedge of subchondral bone and its overlying cartilage dies and becomes detached from the articular surface. Although it occurs most often in the knee joint of young male athletes, other reported sites of involvement include the patella, the capitellum, the talar dome, and the femoral head.I In contrast, the occ...
