The invention is directed toward a cartilage repair assembly (10) comprising a shaped allograft construct comprising a cylindrical mineralized cancellous bone base member (12) and a demineralized cancellous bone cap member (20) having a cylindrical top portion (22) and a stem (26) extending from the top portion (22) mounted to the bone base member (12). The base member (12) has a central bore (14) and a transverse bore (16) which intersects the central bore (14) and the cap member stem (26) has a through-going bore (28) which is aligned with the base member transverse bore (16) when the stem (26) is mounted in the central bore (14) to receive a pin member (30). Milled cartilage particles having a size ranging from 10 to 212 microns are mixed with a biocompatible carrier and a cartilage growth factor, with the mixture being infused in the cap member (20) to generate cartilage growth.
L'invention porte sur un ensemble de réparation de cartilage (10), comprenant une structure d'allogreffe façonnée comprenant un élément de base osseux spongieux minéralisé cylindrique (12) et un élément de couvercle osseux spongieux déminéralisé (20) ayant une partie supérieure cylindrique (22) et une tige (26) s'étendant à partir de la partie supérieure (22) montée sur l'élément de base osseux (12). L'élément de base (12) a un alésage central (14) et un alésage transversal (16) qui coupe l'alésage central (14) et la tige d'élément de couvercle (26) a un trou traversant (28) qui est aligné avec l'alésage transversal d'élément de base (16) lorsque la tige (26) est montée dans l'alésage central (14) pour recevoir un élément de broche (30). Des particules de cartilage broyées ayant une dimension allant de 10 à 212 microns sont mélangées avec un support biocompatible et un facteur de croissance de cartilage, le mélange étant infusé dans l'élément de couvercle (20) pour générer une croissance de cartilage.
