Claims5
A customized patient-specific tibial cutting block, comprising:
- a body having a bone-facing surface that has a customized patient-specific negative contour configured to receive a portion of an anterior side of a patient's tibia that has a corresponding positive contour;
- an outer surface opposite the bone-facing surface, the outer surface having a recessed area sized to receive an end of a surgeon's finger, the recessed area corresponding to a location on the body at which pressure is to be applied to couple the customized patient-specific tibial cutting block to the patient's tibia;
- at least one tab extending posteriorly from the body, the at least one tab having a bone-facing surface having a customized patient-specific negative contour configured to receive a portion of the proximal side of the patient's tibia that has a corresponding positive contour;
- and a cutting guide coupled to the body, wherein:
- the cutting guide has a cutting slot defined therein, and the cutting guide is formed from a material different from the body and being positioned to allow a surgeon to perform a proximal cut on the patient's tibia using the cutting slot, wherein the cutting guide is formed from a metallic material and is overmolded to the body of the customized patient-specific femoral cutting block.
