1. An artificial meniscal scaffold for placement in a knee joint, the artificial meniscal scaffold comprising:
an arcuate bioresorbable matrix;
a network of circumferential bioresorbable fibers embedded in said matrix; and
a network of orthogonal bioresorbable fibers embedded in said matrix to prevent separation of said circumferential fiber network;
wherein the bioresorbable circumferential fibers and the bioresorbable orthogonal fibers have a three-dimensional shape and geometry which is substantially the same as the three-dimensional shape and geometry of the matrix;
wherein the scaffold is comprised of an anterior end, a posterior end, and a middle section therebetween defining a curved path between said anterior and posterior ends;
wherein the network of circumferential bioresorbable fibers extends between said anterior and posterior ends along the path of said curve and exits the anterior and posterior ends of the scaffold to form respective anterior and posterior attachment segments;
wherein the anterior and posterior attachment segments have a proximal region, a distal region, a length, and an exterior surface;
wherein a polymeric fiber is wound multiple times around at least a portion of an exterior surface of the middle section to protect the circumferential and orthogonal bioresorbable fibers embedded in the arcuate bioresorbable matrix;
wherein the polymeric fiber is laced through holes in the arcuate bioresorbable matrix and secured by knots to the exterior surface of the middle section of the arcuate bioresorbable matrix; and,
wherein the artificial meniscal scaffold is a C-shaped disc with a wedge-like cross-section.
