An orthopedic implant includes a first portion including at least one feature modified to be patient-specific and match the anatomy of a specific patient from a three-dimensional digital image of a patient's joint using computer modeling. The orthopedic implant includes a non-custom inner bone-engaging surface including a plurality of planar surfaces configured for engagement with non-custom bone cuts.

1. An orthopedic implant system comprising: a plurality of orthopedic implants comprising:an inner bone-engaging surface having a length in an anterior-posterior direction that is standardized so as to be independent of an anatomy of a specific patient's joint but is rather one of a series of predetermined size increments for the orthopedic implant system with the length in the anterior-posterior direction of each of the plurality of orthopedic implants differing, each size increment varying by a set amount of the length in the anterior-posterior direction relative to others, wherein the inner bone-engaging surface includes a plurality of planar surfaces configured for engagement with bone cuts to a femur, the bone cuts having an overall length when combined in the anterior-posterior direction that is configured to correspond to that of the inner bone-engaging surface of the orthopedic implant; andat least one of the plurality of orthopedic implants having a joint facing portion opposing the inner bone-engaging surface including at least one feature configured to be patient-specific based on an image of the specific patient's joint, wherein the at least one feature is designed using computer modeling to have a shape dependent upon an anatomy of the specific patient. 2. The orthopedic implant system of claim 1, wherein the series of size increments are in increments of 3 mm or less. 3. The orthopedic implant system of claim 1, wherein the at least one feature is a medial/lateral width of the at least one of the plurality of orthopedic implants. 4. The orthopedic implant system of claim 1, wherein the orthopedic implant is a femoral knee implant and the at least one feature includes an orientation of a patella track of the femoral knee implant. 5. The orthopedic implant system of claim 1, wherein the orthopedic implant is a femoral knee implant and the at least one feature includes a depth of a patella track of the femoral knee implant. 6. The orthopedic implant system of claim 1, wherein the orthopedic implant is a femoral knee implant and the at least one feature includes a shape of an anterior flange of the femoral knee implant. 7. The orthopedic implant system of claim 1, wherein the orthopedic implant is a femoral knee implant and the at least one feature includes a height of an anterior flange of the femoral knee implant. 8. An orthopedic implant system comprising: a plurality of orthopedic implants comprising:an inner bone-engaging surface including a plurality of planar surfaces configured for engagement with corresponding femoral bone cuts, wherein the plurality of orthopedic implants are standardized so as to be independent of the anatomy of a specific patient's joint but each of the plurality of orthopedic implants has a different length in an anterior-posterior direction that is one of a series of predetermined size increments for the implant system, wherein each size increment varies by a set amount of length in the anterior-posterior direction relative to others, and wherein selection of which one of the plurality of orthopedic implants is utilized is made by ascertaining a closest fit from the plurality of orthopedic implants by overlaying the plurality of orthopedic implants on an image of the specific patient's joint using computer modeling; andat least one of the plurality of implants having a joint facing portion opposing the inner bone-engaging surface configured during a preoperative plan to have a patient-specific feature based on the image of the specific patient's joint, wherein the patient-specific feature is designed using computer modeling to have a shape dependent upon the anatomy of the specific patient by modifying a computer model of the one of the plurality of orthopedic implants selected to provide for the patient specific feature, wherein the computer model includes a plurality of planar surfaces corresponding to the plurality of planar surfaces of the inner bone-engaging surface of the one of the plurality of orthopedic implants selected that remain unmodified. 9. The orthopedic implant system of claim 8, wherein the patient-specific feature includes a medial/lateral width. 10. The orthopedic implant system of claim 8, wherein the joint facing portion includes an anterior flange and the patient-specific feature includes a shape of the anterior flange. 11. The orthopedic implant system of claim 8, wherein the joint facing portion includes an anterior flange and the patient-specific feature includes a height of the anterior flange. 12. The orthopedic implant system of claim 8, wherein the joint facing portion includes a patella track and the patient-specific feature includes an orientation of the patella track. 13. The orthopedic implant system of claim 8, wherein the joint facing portion includes a patella track and the patient-specific feature includes a depth of the patella track. 14. The orthopedic implant system of claim 8, wherein the joint facing portion includes an anterior flange and the patient-specific feature includes a medial/lateral width of the first portion, a shape of the anterior flange, and a height of the anterior flange. 15. The orthopedic implant system of claim 14, wherein the joint facing portion includes a patella track and the patient-specific feature includes an orientation of the patella track and a depth of the patella track. 16. An orthopedic implant system comprising: a plurality of orthopedic implants comprising:an inner bone-engaging surface having a length in an anterior-posterior direction that is standardized so as to be independent of an anatomy of a specific patient's joint but is rather one of a series of predetermined size increments for the orthopedic implant system with the length in the anterior-posterior direction of each of the plurality of orthopedic implants differing, each size increment varying by a set amount of the length in the anterior-posterior direction relative to others, wherein the inner bone-engaging surface includes a plurality of planar surfaces configured for engagement with bone cuts, the bone cuts having an overall length when combined in the anterior-posterior direction that is configured to correspond to that of the inner bone-engaging surface of the orthopedic implant; andat least one of the plurality of orthopedic implants having one or more of an orientation of a patella track, a depth of the patella track, a height of an anterior flange, a shape of the anterior flange, and a medial/lateral width that is configured to be patient-specific based on an image of the specific patient's joint, wherein the at least one feature is designed using computer modeling to have a shape dependent upon an anatomy of the specific patient.
