ABSTRACT:
A prosthetic, resorbable meniscus and method of its fabrication are disclosed. The prosthetic meniscus can be implanted in a human knee where it can act as a scaffold for regrowth of native meniscal tissues. The meniscus comprises a dry, porous, matrix of biocompatible and bioresorbable fibers, at least a portion of which may be crosslinked. The fibers include natural polymers or analogs or mixtures thereof. The matrix is adapted to have in vivo an outer surface contour substantially the same as that of a natural meniscus. The matrix has pore size in the approximate range of greater than 50 microns to less than about 500 microns. With this configuration, the matrix establishes an at least partially bioresorbable scaffold adapted for ingrowth of meniscal fibrochondrocytes.
