title: [Condylar osteonecrosis of the knee in adults and aged. Study of 36 cases].
abstract: The authors analyse the clinical symptoms, the etiology, and the evolution of condylar osteonecrosis of the knee with reference to 36 personal cases, including 28 unilateral forms and 8 bilateral forms. They confirm the predominance of the condition in women and the fact that it usually commences after the age of 50 years. They followed the evolution of the condition in 27 patients, in 20 of them for from 3 to 12 years. Evolution was good or excellent in 12 patients. The authors showed that the existence of a healthy lateral segment on the affected condyle is one element that indicates a good prognosis; they found that intra-articular injections of corticoids did not affect the evolution unfavourably, but that the coexistence of several other associated pathological conditions (vasxular, metabolic...) indicated a poor prognosis. If the precipitating cause of the condylar osteonecrosis of the knee is not known, with the exception of some cases commencing after trauma, the authors put forward the hypothesis of chronic condylar circulatory insufficiency or stasis as the cause leading to the condition, the latter occurring in cases when an already delicate vascular equilibrium is upset.
