Figure 6 illustrates a perspective view of a first cuneiform and a first metatarsal with one embodiment of a patient-specific cutting guide positioned over a TMT joint. In the illustrated embodiment, the first resection feature may take the form of the first slot 660 and the second resection feature may take the form of the second slot 670. As with the embodiment of Figures 3A-19H and 20, the position and/or angles (e.g., orientation) of one or both of the resection features based on patient imaging data is illustrated. The first slot 660 is oriented based on a desired angle for mitigating the condition of the patient. In one example, the first slot 660 is angled perpendicular to a longitudinal axis 676 of the first metatarsal 208. This orientation of the first slot 660 enables the first cut surface to extend from the body 610 toward the bone to form a cut surface that is also perpendicular to the longitudinal axis 676 of one of the bones of a joint.
