1. A method for producing cartilage fibers comprising:
grating recovered cartilage using a grater having a plurality of cutting features, each of which has an opening and a raised cutting surface with a cutting edge which was formed by a die stamping technique, to produce a plurality of cartilage fibers each having three or more laterally-oriented striations and which enable the cartilage fibers to entangle with one another to a greater degree than cartilage fibers without such striations and form a cohesive mass having a shape and which retains said shape until reshaped and, when implanted in a shaped cavity of a cartilage defect, is capable of conforming to and completely filling the shaped cavity and resists swelling, deformation, and migration from the shaped cavity upon hydration with a fluid to a greater degree than cartilage fibers without such striations; and
optionally, storing the plurality of cartilage fibers in storage media.
