1. An artificial meniscus implant comprising:
an arc-shaped body comprising a polymer material that inhibits cell ingrowth and having a peripheral edge, an interior edge, a first horn, and a second horn positioned proximate opposing ends of an arc-shaped length of the arc-shaped body, the arc-shaped body defining a circumferential direction extending between the first horn and the second horn and a radial direction perpendicular to the circumferential direction;
a plurality of first fibers embedded in the arc-shaped body and defining a first fiber longitudinal length that extends in the circumferential direction, each of the plurality of first fibers comprising a first end portion having a first interconnected fiber structure protruding beyond the first horn of the arc-shaped body and a second end portion having a second interconnected fiber structure protruding beyond the second horn of the arc-shaped body, wherein the plurality of first fibers are not interconnected within the arc-shaped body; and
at least one second fiber embedded in the arc-shaped body, each of the at least one second fiber extending along at least a portion of a radial width of the arc-shaped body between the peripheral edge and the interior edge, defining a second fiber longitudinal length that extends in the radial direction, and not in contact with and spaced apart from the plurality of first fibers, the first interconnected fiber structure, and the second interconnected fiber structure.
