A method of preparing a distal femur for a knee joint implant includes mounting a patient-specific bone engagement surface of a femoral alignment guide on a complementary surface of a distal femur of a patient. A plurality of alignment pins is inserted through a corresponding plurality of guiding bores of the femoral alignment guide into the distal femur. A cutting guide is mounted on first and second alignment pins of the plurality of alignment pins, and a first resection of the distal femur is made using the cutting guide while cutting through the femoral alignment guide.
1. A tibial alignment guide for preparing a tibia of a patient for resection during joint arthroplasty, the tibial alignment guide comprising: a first portion engageable with a proximal surface of the tibia, the first portion defining first and second proximal guiding bores and an opening between th
1. A tibial alignment guide for preparing a tibia of a patient for resection during joint arthroplasty, the tibial alignment guide comprising: a first portion engageable with a proximal surface of the tibia, the first portion defining first and second proximal guiding bores and an opening between the first and second proximal guiding bores; a second portion engageable with an anterior surface of the tibia, the second portion defining first and second anterior guiding bores; and a plurality of alignment pins receivable through respective proximal and anterior guiding bores for attaching the alignment guide to the tibia, wherein the alignment pins are configured to be resorbable in vivo and are configured to be divided into one or more portions with at least one of the one or more portions retained within the tibia of after the resection, wherein the plurality of alignment pins are cannulated and configured to receive pins of a cutting block. 2. The tibial alignment guide of claim 1, wherein the opening of the first portion defines a plurality of fin-shaped slots for receiving a finned stem punch. 3. The tibial alignment guide of claim 1, further comprising a removable metal insert shaped to be mateably and removably received in the opening of the first portion. 4. The tibial alignment guide of claim 3, wherein the metal insert defines a plurality of fin-shaped slots for receiving a finned stem punch. 5. The tibial alignment guide of claim 3, further comprising a modular handle removably coupled to the metal insert. 6. The tibial alignment guide of claim 3, wherein the metal insert defines a plurality of apertures configured to fit over and align with the first and second proximal guiding bores. 7. The tibial alignment guide of claim 1, wherein the guide has a patient-specific bone engagement surface defined by the first and second portions and complementary to the proximal and anterior surface of the tibia. 8. The tibial alignment guide of claim 7, wherein the patient-specific bone engagement surface is configured to be complementary so as to closely conform and mate with the proximal and anterior surface of the tibia in only one position based upon a preoperative plan. 9. The tibial alignment guide of claim 1, wherein the second portion defines an elongated slot for guiding a blade during the resection of the tibia. 10. The tibial alignment guide of claim 9, wherein the plurality of alignment pins are cut off by the blade during the resection of the tibia. 11. An orthopedic device comprising: a patient-specific tibial alignment guide operable for preparing a tibia of a patient for resection during joint arthroplasty, the tibial alignment guide including: a first portion engageable with a proximal surface of the tibia, the first portion defining first and second proximal guiding bores and an opening between the first and second proximal guiding bores; a second portion engageable with an anterior surface of the tibia, the second portion defining first and second anterior guiding bores and an elongated slot for guiding a blade for resecting of the tibia; a patient-specific bone engagement surface defined by the first and second portions and complementary to the proximal and anterior surface of the tibia; and a plurality of alignment pins receivable through respective proximal and anterior guiding bores for attaching the alignment guide to the tibia, wherein the alignment pins are configured to be resorbable and are configured to be cut off during resection of the tibia, wherein the plurality of alignment pins are cannulated and configured to receive pins of a cutting block. 12. The orthopedic device of claim 11, wherein the opening of the first portion defines a plurality of fin-shaped slots for receiving a finned stem punch. 13. The orthopedic device of claim 11, further comprising a removable metal insert shaped to be mateably and removably received in the opening of the first portion. 14. The orthopedic device of claim 13, wherein the metal insert defines a plurality of fin-shaped slots for receiving a finned stem punch. 15. The orthopedic device of claim 11, further comprising a modular handle removably coupled to the metal insert. 16. The orthopedic device of claim 11, wherein the plurality of alignment pins are cut off by the blade during the resection of the tibia. 17. An orthopedic system comprising: a patient-specific alignment guide operable for preparing a bone of a patient for resection during joint arthroplasty, the alignment guide including a patient-specific bone engagement surface configured to be complementary to a surface of the bone of the patient, the alignment guide including a plurality of guiding bores;a plurality of alignment pins receivable through corresponding guiding bores for attaching the alignment guide to the bone, wherein the alignment pins are cannulated and are configured to be cut off during a resection of the bone; anda cutting block including a plurality of pins configured to be receivable into corresponding cut-off portions of the alignment pins for a second resection of the bone. 18. The orthopedic system of claim 17, wherein the alignment guide is configured to be cut off during a resection of the bone. 19. The orthopedic system of claim 17, wherein the alignment pins are resorbable.
