Abstract
A prospective experiment was carried out in 40 rabbits in which the blood supply to the patella was interrupted for defined periods from 2 weeks to 6 months. With prolonged ischaemia, there were clear changes in the articular cartilage which were comparable with those seen in human osteoarthritis. On a entrepris, sur 40 lapins, un travail expérimental prospectif en interrompant la vascularisation de la rotule durant des périodes allant de 2 semaines à 6 mois. On a constaté qu'une ischémie prolongée entraîne des modifications notables du cartilage articulaire, comparables à celles que l'on observe chez l'homme en cas d'arthrose.
