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 method for a partial socket replacement comprising: mounting a patient-specific acetabular guide on an acetabulum of a patient, wherein the acetabular guide is configured to mate to the patient's acetabulum in only one position;guiding a cutting tool through a patient-specific bore of the aceta
1. A method for a partial socket replacement comprising: mounting a patient-specific acetabular guide on an acetabulum of a patient, wherein the acetabular guide is configured to mate to the patient's acetabulum in only one position;guiding a cutting tool through a patient-specific bore of the acetabular guide, wherein the patient-specific bore of the acetabular guide is configured to overlay a defect in the acetabulum of the patient;removing damaged tissue of the defect;forming a patient-specific implantation slot by removing the damaged tissue,engaging a patient-specific inverse acetabular guide to allograft tissue;guiding a cutting tool along a guiding slot of the patient-specific inverse acetabular guide, the guiding slot configured during the preoperative plan to mate with a wall of the patient-specific implantation slot; andextracting a patient-specific partial acetabular implant from the allograft tissue; andimplanting the patient-specific partial acetabular implant in the patient-specific slot, wherein the implant is the allograft tissue implant. 2. The method of claim 1, wherein the partial acetabular implant has a peripheral surface configured to mate with a wall of the patient-specific implantation slot. 3. The method of claim 2, wherein the partial acetabular implant has an outer surface configured to be continuous with a surrounding cartilage after implantation. 4. The method of claim 1, further comprising anchoring the patient-specific partial acetabular implant in the acetabulum using an anchoring element. 5. The method of claim 1, wherein the acetabular guide has a first curved three-dimensional surface configured to nestingly mate in only one position to the patient's acetabulum, and a second planar surface opposite the first surface, and wherein the bore is an open bore extending between the first and second surfaces. 6. The method of claim 5, further comprising controlling a depth of the patient-specific implantation slot. 7. The method of claim 6, wherein controlling a depth of the patient-specific implantation slot includes engaging a three-dimensional depth control surface of the acetabular guide to a corresponding outer surface of a distal portion of a handle of the cutting tool. 8. The method of claim 7, wherein the depth control surface extends from the planar second surface of the acetabular guide. 9. A method for a partial socket replacement comprising: mounting a patient-specific acetabular guide on an acetabulum of a patient, wherein the acetabular guide has a first curved three-dimensional surface configured to nestingly mate to the patient's acetabulum, including the acetabulum's articular cartilage and acetabular fossa in only one position;guiding a cutting tool through a patient-specific bore of the acetabular guide, wherein the patient-specific bore passes through the first surface of the acetabular guide and is configured to overlay a defect in the acetabulum of the patient;removing damaged tissue of the defect;forming a patient-specific implantation slot; andcontrolling a depth of the patient-specific implantation slot by the acetabular guide physically constraining the cutting tool from advancing further into the acetabulum. 10. The method of claim 9, wherein the acetabular guide has a second planar surface opposite the first surface, and wherein the bore is an open bore extending between the first and second surfaces. 11. The method of claim 10, wherein controlling a depth of the patient-specific implantation slot includes engaging a three-dimensional depth control surface of the acetabular guide to a corresponding outer surface of a distal portion of a handle of the cutting tool. 12. The method of claim 11, wherein the depth control surface extends from the planar second surface of the acetabular guide. 13. The method of claim 9, further comprising implanting a patient-specific partial acetabular implant in the patient-specific implantation slot. 14. The method of claim 13, wherein the partial acetabular implant has a peripheral surface configured to mate with a wall of the patient-specific implantation slot. 15. The method of claim 14, wherein the partial acetabular implant has an outer surface configured to be continuous with a surrounding cartilage after implantation. 16. The method of claim 13, further comprising anchoring the patient-specific partial acetabular implant in the acetabulum using an anchoring element. 17. A method for a partial socket replacement comprising: mounting a patient-specific acetabular guide on an acetabulum of a patient, wherein the acetabular guide has a first curved three-dimensional surface configured to nestingly mate to the patient's acetabulum, including the acetabulum's articular cartilage and acetabular fossa in only one position, and a second planar surface opposite the first surface;guiding a cutting tool through a patient-specific bore of the acetabular guide, wherein the patient-specific bore extends through the first and second surfaces of the acetabular guide and is configured to overlay a defect in the acetabulum of the patient;removing damaged tissue of the defect;forming a patient-specific implantation slot; andcontrolling a depth of the patient-specific implantation slot by the acetabular guide physically constraining the cutting tool from advancing further into the acetabulum.
