9. An orthopedic implant comprising:
-
a non-custom inner bone-engaging surface including a plurality of planar surfaces configured for engagement with standard size femoral bone cuts prepared for a non-custom femoral implant; and a first portion configured during a preoperative plan to have a patient-specific feature and to closely match a corresponding portion of a femur of a specific patient based on a three-dimensional digital image of a patient'"'"'s joint using computer modeling, wherein the patient-specific feature is obtained by modifying a digital image of the non-custom femoral implant without modifying the plurality of planar surface of the inner bone-engaging surface. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. An orthopedic implant comprising:
-
a tibial bearing including a non-custom portion; and a tibial tray including a non-custom locking mechanism configured to be coupled with the non-custom portion of the tibial bearing, wherein the tibial tray has a patient-specific profile configured during a preoperative plan to closely match a corresponding profile of a tibia of a specific patient based on a three-dimensional digital image of a patient'"'"'s joint using computer modeling, wherein the patient-specific profile of the tibial tray is obtained by modifying a digital image of a non-custom tibial implant without modifying the non-custom locking mechanism. - View Dependent Claims (18, 19, 20)
