A device for partial acetabular replacement includes a patient-specific acetabular guide. The acetabular guide has a first surface configured to nestingly mate in only one position to the patient's acetabulum. The acetabular guide includes a patient-specific guiding formation configured to guide a cutting tool to remove damaged tissue from a defect of the patient's acetabulum and prepare a patient-specific implantation slot corresponding to the defect after removal of the damaged tissue. A patient-specific partial acetabular implant can be configured to nestingly mate with the patient-specific implantation slot.
1. A device for partial acetabular replacement comprising: a patient-specific acetabular guide having a first curved three-dimensional surface configured to nestingly mate in only one position to the patient's acetabulum including the acetabulum's articular cartilage and acetabular fossa, the acetab
1. A device for partial acetabular replacement comprising: a patient-specific acetabular guide having a first curved three-dimensional surface configured to nestingly mate in only one position to the patient's acetabulum including the acetabulum's articular cartilage and acetabular fossa, the acetabular guide having a patient-specific guiding formation configured to guide a cutting tool to remove a cartilage defect of the patient's acetabulum and prepare the acetabulum for a patient-specific partial acetabular implant;wherein the acetabular guide includes a second planar outer surface and the guiding formation is an open bore extending from the second surface and through the first surface. 2. The device of claim 1, wherein the guiding formation is a bore through the acetabular guide. 3. The device of claim 1 in combination with a patient-specific partial acetabular implant configured to be received in a patient-specific implantation slot formed by removing the cartilage defect using the acetabular guide. 4. The combination of claim 3, wherein the partial acetabular implant has a three-dimensional peripheral surface configured to mate with a wall of the patient-specific implantation slot. 5. The combination of claim 4, wherein the partial acetabular implant has an outer surface configured to be continuous with a surrounding cartilage after implantation for femoral joint articulation. 6. The combination of claim 4, wherein the partial acetabular implant includes an anchoring element for engaging the acetabulum of the patient. 7. The combination of claim 3, wherein the partial implant is an allograft implant. 8. The combination of claim 3, further including an inverse acetabular guide configured during the preoperative plan of the patient for extracting the partial acetabular implant from allograft tissue. 9. The device of claim 1, wherein the patient-specific acetabular guide includes a depth control surface configured to mate with a distal portion of a handle of a cutting tool for controlling a cutting depth through the guiding formation. 10. A device for partial acetabular replacement comprising: a patient-specific acetabular guide having a first surface configured to nestingly mate in only one position to the patient's acetabulum and a patient-specific guiding formation configured to guide a cutting tool to remove damaged tissue from a defect of the patient's acetabulum and prepare a patient-specific implantation slot corresponding to the defect after removal of the damaged tissue; anda patient-specific partial acetabular implant configured to nestingly mate with the patient-specific implantation slot. 11. The device of claim 10, wherein the first surface is a curved three-dimensional surface configured to mate with portions of an articular cartilage and an acetabular fossa of the acetabulum. 12. The device of claim 10, wherein the guiding formation is a bore through the acetabular guide. 13. The device of claim 10, wherein the acetabular guide includes a second planar outer surface and the guiding formation is an open bore extending from the second surface and through the first surface. 14. The device of claim 10, wherein the partial acetabular implant has a three-dimensional peripheral surface configured to mate with a wall of the patient-specific implantation slot. 15. The device of claim 14, wherein the partial acetabular implant has an outer surface configured to be continuous with a surrounding cartilage after implantation for femoral joint articulation. 16. The device of claim 14, wherein the wall of the patient-specific implantation slot is configured as an envelope of the defect. 17. The device of claim 13, wherein the partial acetabular implant includes an anchoring element for engaging the acetabulum of the patient. 18. The device of claim 10, further comprising an inverse acetabular guide configured during a preoperative plan of the patient for extracting the patient-specific partial acetabular implant from allograft tissue. 19. A device for partial acetabular replacement comprising: a patient-specific acetabular guide having a first curved three-dimensional surface configured to nestingly mate in only one position to the patient's acetabulum including the acetabulum's articular cartilage and acetabular fossa, the acetabular guide having a patient-specific guiding formation configured to guide a cutting tool to remove a cartilage defect of the patient's acetabulum and prepare the acetabulum for a patient-specific partial acetabular implant;wherein the patient-specific acetabular guide includes a depth control surface configured to mate with a distal portion of a handle of a cutting tool for controlling a cutting depth through the guiding formation.
