A method of distributing a load to a cartilage defect repair plug is
provided. A load is applied to a first articulation layer. The load is
distributed to a second layer and the load is transferred in the normal
direction to the first density of subchondral bone. The load is
distributed to a third layer and the load is transferred in the normal
direction to a second density of subchondral bone. The load is then
distributed to a fourth layer and the load is transferred in the normal
direction to a third density of subchondral bone.
