1. A meniscal augmentation device for implantation into a segmental defect of a meniscus in a subject, the device comprising a plurality of biocompatible and at least partially bioresorbable fibers, wherein the device has an outer surface contour substantially complementary to the segmental defect of the meniscus, and the fibers are selected from the group consisting of natural polymers, analogs of natural polymers, and mixtures of natural polymers and/or analog polymers,wherein the device, when implanted into the segmental defect of the meniscus, establishes a biocompatible and an at least partially bioresorbable scaffold which comprises a dry, porous volume matrix having a pore size ranging from about 50 microns to about 500 microns and is adapted for the ingrowth of meniscal fibrochondrocytes, the scaffold and the ingrown meniscal fibrochondrocytes support natural meniscal load forces, and the in vivo outer surface of the composite of said meniscus and said device is substantially the same as that of a natural meniscus without segmental defects.
