A method of treating a synovial joint by injecting particles of collagen-based material into the joint. The particles may be dehydrated before implantation, and rehydrated after implantation, or they may be implanted in a "wet" state - such as a slurry or gel. Radiocontrast materials may be included to enhance imaging of the injected material. Other additives may include analgesics, antibiotics, proteoglycans, growth factors, and/or other cells effective to promote healing and/or proper joint function.
L'invention concerne un procédé permettant de traiter une articulation synoviale par injection de particules d'un matériau à base de collagènes dans l'articulation. Les particules peuvent être déshydratées avant d'être implantées, puis réhydratées après implantation, ou encore, elles peuvent être implantées à l'état "humide" (par exemple, sous forme de pâte ou de gel). Des matériaux de contraste radiologique peuvent être incorporés de manière à augmenter la visualisation du matériau injecté. D'autres additifs peuvent comprendre des analgésiques, des antibiotiques, des protéoglycanes, des facteurs de croissance, et/ou d'autres cellules permettant de favoriser la cicatrisation et/ou la bonne fonction articulaire.
