Title (EN) ASSESSING THE CONDITION OF A JOINT AND DEVISING TREATMENT
(FR) ÉVALUATION DE L'ÉTAT D'UNE ARTICULATION ET TRAITEMENT AFFÉRENT
Abstract:
(EN) Methods are disclosed for assessing the condition of a cartilage in a joint, particularly a human knee. The methods include converting an image such as an MRI to a three dimensional map of the cartilage. The cartilage map can be correlated to a movement pattern of the joint to assess the affect of movement on cartilage wear. Changes in the thickness of cartilage over time can be determined so that therapies can be provided. Information on thickness of cartilage and curvature of cartilage or subchondral bone can be used to plan therapy. Information on movement pattern can be used to plan therapy.
(FR) Cette invention a trait à des méthodes d'évaluation de l'état du cartilage d'une articulation, notamment celui du genou. On convertit, dans le cadre de ces méthodes, une image, par exemple une image obtenue par résonance magnétique, en projection tridimensionnelle du cartilage. Il est possible de mettre en corrélation cette figuration du cartilage avec un schéma de mouvement de l'articulation, ce qui permet d'évaluer l'incidence du mouvement sur l'usure du cartilage. La détermination des variations d'épaisseur du cartilage dans le temps sert à mettre au point des thérapies adaptées. On peut utiliser les renseignements relatifs à l'épaisseur, à la courbure du cartilage ou de l'os sous-chondral, ainsi que ceux portant sur le schéma de mouvement pour planifier une thérapie.
