We evaluated the histological changes before and after fixation in ten knees of ten patients with osteochondritis dissecans who had undergone fixation of the unstable lesions. There were seven males and three females with a mean age of 15 years (11 to 22). The procedure was performed either using bio-absorbable pins only or in combination with an autologous osteochondral plug. A needle biopsy w...

THE purpose of this paper is to establish the incidence of osteochondritis dissecans in the age group in which it is known to occur most commonly. In the services, the majority of men are ag~d 18-30 years and thereby constitute this age group. The total number of men reporting sick, whose signs and symptoms required a radiograph of a particular joint, were taken as the index for com.parison. Fo...

The cause of OCD is still debated: the most recognized etiology is the occurrence of repetitive micro-traumas associated with vascular impairment, causing progressive ankle pain and dysfunction in sk...

Osteochondritis dissecans (OCD) can affect both adults and children, however the imaging characteristics and significance of imaging findings can differ in the juvenile subset with open physes. Radiography and magnetic resonance imaging (MRI) are the primary modalities used to aid in diagnosis, to define a treatment plan, to monitor progress, to assess surgical intervention, and to identify pos...
