The present invention overcomes the problems of conventional mechanical endoprostheses and the drawbacks of current methods of cartilage replacement by making provisions for the production of a complete biological joint replacement. In order to produce a biological joint replacement having hyaline cartilage, which can cope with heavy loads, devices are used for the shaping, the promotion of diffusion and in particular the compression of the joint replacement that is to be produced, i.e. a compression with alternating pressures and eventually a sliding movement of the walker on the surface of the joint replacement. The invention also relates to substances and methods for promoting the formation of hyaline cartilage tissue. The biological joint replacement is currently preferably suited for implantation in the shoulder and the hip, but can also be applied to other joints by using multi-dimensional milling techniques. |
