FIG. 23 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 guide feature may take the form of the first slot 2260 and the second guide feature may take the form of the second slot 2270. As with the embodiment of FIGS. 19A-19H and 20, the position and/or angles (e.g., orientation) of one or both of the guide features based on patient imaging data is illustrated. The first slot 2260 is oriented based on a desired angle for mitigating the condition of the patient. In one example, the first slot 2260 is angled perpendicular to a longitudinal axis 2276 of the first metatarsal 230. This orientation of the first slot 2260 enables the first cut surface to extend from the body 2210 toward the bone to form a cut surface that is also perpendicular to the longitudinal axis 2276 of one of the bones of a joint.
