We examined radiographs of the inferior pole of the patella in seven juvenile athletes diagnosed as having Sinding-Larsen-Johansson disease (SLJD) and discussed the etiology of the syndrome. Eight knees had tenderness at the inferior pole of the patella accompanied by radiographic abnormalities. A regular or irregular calcification was found at the inferior pole of the patella in three knees; c...

The discoid meniscus is a rare anomaly of the knee that affects mostly the lateral meniscus and is often asymptomatic. The osteochondritis dissecans is a disorder of the subchondral bone and articular cartilage and occurs frequently associated with the discoid lateral meniscus. In the present case, we showed the evolution of this association related to surgical treatment. A patient with lateral...

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...

OBJECTIVE To estimate prevalences of various presale radiographic findings and of presale arthroscopy in horses offered for sale at the 2006 Keeneland September yearling sale and to compare sales prices between yearlings with and without various presale radiographic findings or a history of arthroscopy. ANIMALS 397 Thoroughbred yearlings. DESIGN Cross-sectional study. PROCEDURES Presale r...

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...
