An orthopedic device for cutting or resurfacing an outer bone surface of a bone of a patient includes first and second guides. Each guide has a patient-specific surface preoperatively configured as a negative surface of a portion of the outer bone surface of the bone and a plurality of elongated slots. The elongated slots of the second guide are offset relative to the elongated slots of the first guide and configured for guiding a tool to resurface the outer bone surface.

1. A patient-specific alignment guide system for cutting or resurfacing an outer bone surface of a bone of a patient, the alignment guide system comprising: a patient-specific alignment guide having an engagement surface mirroring the outer bone surface;a first guiding formation connected to the alignment guide on a non-engaging surface to direct a reference pin into the bone at a desired location;a reference pin configured to extend through the first guiding formation; anda cutting effector system comprising: a vibratory cutting tool having a patient-specific cutting support surface mirroring the outer bone surface and a patient-specific cutting surface including grinding elements;a guide member for coupling to the reference pin, the guide member comprising an angled guiding shaft having a distal portion angled with respect to a proximal portion; anda guide connecting the vibratory cutting tool and the guide member, the guide comprising: a guide tube slidably engaged with the proximal portion of the angled guiding shaft; anda connector extending from the guide tube and connected to the vibratory cutting tool:wherein the angled guiding shaft and the connector are sized and shaped so that the guide tube can be translated on the proximal portion of the angled guiding shaft so that the patient-specific cutting surface can engage the outer bone surface that is mirrored by the patient-specific cutting support surface; andwherein the guide is translatable on the guide member to bring the cutting surface into engagement with the outer bone surface. 2. The patient-specific alignment guide system of claim 1, further comprising a second guiding formation connected to the alignment guide on the non-engaging surface to direct a reference pin into the bone at a second desired location. 3. The patient-specific alignment guide system of claim 2, wherein the first guiding formation comprises an anterior guiding formation for locating on an anterior surface of a femur between condyles, and the second guiding formation comprises a distal guiding formation for locating on a distal surface of a condyle of the femur. 4. The patient-specific alignment guide system of claim 1, wherein the patient-specific alignment guide includes a window located entirely within an outer boundary of the patient-specific alignment guide. 5. A cutting effector system for cutting or resurfacing an outer bone surface of a bone of a patient, the cutting effector system comprising: a vibratory cutting tool having a patient-specific cutting surface preoperatively configured to three-dimensionally mirror a three-dimensional digital image of the outer bone surface;a guide member having a reference pin for insertion into the bone at a patient-specific location; anda guide connecting the vibratory cutting tool and the guide member; wherein the guide is translatable on the guide member to bring the patient-specific cutting surface into engagement with the outer bone surface that is mirrored by the patient-specific cutting surface. 6. The cutting effector system of claim 5, wherein the vibratory cutting tool comprises: a patient-specific support surface; andgrinding elements located on the patient-specific cutting surface. 7. The cutting effector system of claim 6, wherein the vibratory cutting tool further comprises: a shaft extending from the patient-specific support surface; anda holder connected to the shaft and the guide. 8. The cutting effector system of claim 5, wherein the guide member comprises: an angled guiding shaft having a distal portion angled with respect to a proximal portion;wherein the reference pin is located at the distal portion of the angled guiding shaft. 9. The cutting effector of claim 5, wherein the guide comprises: a guide tube slidably engaged with the proximal portion of the angled guiding shaft; anda connector extending from the guide tube and connected to the holder; wherein the angled guiding shaft and the connector are sized and shaped so that guide tube can be translated on the proximal portion of the angled guiding shaft so that the patient-specific cutting surface can engage the outer bone surface that is mirrored by the patient-specific cutting surface. 10. A patient-specific cutting system for cutting or resurfacing an outer bone surface of a bone of a patient, the cutting system comprising: a patient-specific resurfacing guide comprising: a guide surface configured to mirror and mate with a corresponding portion of the outer bone surface;a slot extending along the patient-specific resurfacing guide; andan elongated opening extending into the patient-specific resurfacing guide that intersects the slot; anda resurfacing tool configured to ride in the slot to resurface the outer bone surface adjacent the guide surface. 11. The patient-specific cutting system of claim 10, wherein the guide surface of the patient-specific resurfacing guide is configured to track a narrow area between medial and lateral condyles of the bone. 12. The patient-specific cutting system of claim 10, wherein the patient-specific resurfacing guide includes a pin opening configured to receive a guide pin. 13. The patient-specific cutting system of claim 12, further comprising a guide pin configured to be inserted into the pin opening. 14. The patient-specific cutting system of claim 10, wherein the resurfacing tool comprises: a shaft configured to ride in the slot;a peg extending from the shaft and configured to ride in the elongated opening; anda resurfacing member mounted to the peg outside of the patient-specific resurfacing guide, the resurfacing member including a patient-specific resurfacing surface. 15. The patient-specific cutting system of claim 14, wherein the patient-specific resurfacing surface is configured to resurface a condyle. 16. A patient-specific alignment guide system for cutting or resurfacing an outer bone surface of a bone of a patient, the alignment guide system comprising: a patient-specific alignment guide having an engagement surface mirroring the outer bone surface;a first guiding formation connected to the alignment guide on a non-engaging surface to direct a reference pin into the bone at a desired location;a reference pin configured to extend through the first guiding formation; anda patient-specific cutting system comprising: a patient-specific resurfacing guide comprising: a guide surface configured to mirror and mate with a corresponding portion of the outer bone surface;a slot extending along the patient-specific resurfacing guide; andan elongated opening extending into the patient-specific resurfacing guide that intersects the slot; anda resurfacing tool configured to ride in the slot to resurface the outer bone surface adjacent the guide surface, the resurfacing tool comprising: a shaft configured to ride in the slot;a peg extending from the shaft and configured to ride in the elongated opening; anda resurfacing member mounted to the peg outside of the patient-specific resurfacing guide, the resurfacing member including a patient-specific resurfacing surface.
