1. A monolithic medical material wherein the medical material is a medical support matrix containing collagen and having at least a first layer and a second layer, wherein anisotropic pores originate in the first layer and continuously extend from the first layer through the interface of the first layer and the second layer into the second layer, wherein the pores have a columnar, lamellar and/or dendritic structure and wherein the medical support matrix is a chondral support matrix.
