Methods and devices are provided for preparing and implanting tissue scaffolds. Various embodiments of scribing tools (10,50) are provided that are configured to mark one or more predetermined shapes (38) around a defect site (36) in tissue (40). The shape or shapes marked in tissue can be used to cut a tissue scaffold (102,106,136,158) having a shape that matches the shape or shapes marked in tissue. In one embodiment, the scribing tool used to mark a shape in tissue can also be used to cut the tissue scaffold. |
