1. A prosthetic articular cartilage device comprising a dry porous volume matrix of biocompatible and at least partially bioresorbable fibers,said fibers selected from the group consisting of natural polymers, and analogs and mixtures thereof, said matrix being adapted to have an in vivo outer surface contour substantially the same as that of natural articular cartilage, said matrix having a pore size in the approximate range of about 100 microns to about 400 microns,whereby said matrix establishes a bioresorbable scaffold adapted for the ingrowth of articular chondrocytes, and for supporting natural articulating joint forces.
