1. A surgical assistance apparatus for a knee joint operation comprising:
a projector;
a data storage device; and
a Central Processing Unit (CPU) that is communicatively coupled to the projector and the data storage device, wherein the CPU:
stores, in the data storage device, measurements of a knee joint of a patient;
creates a predetermined image projection data based on the measurements of the knee joint of the patient stored in the data storage device,
determines an intraoperative image of the knee joint of the patient and a postoperative image of the knee joint of the patient based on the predetermined image projection data,
creates a projection image based on the predetermined image data, wherein the projection image may include at least one of the intraoperative image of the knee joint of the patient and the postoperative image of the knee join of the patient,
determines, in advance of a surgical operation, alignment parameters to align the projection image on to the patient,
projects, using the projector, the projection image onto the patient based on the alignment parameters,
sets predetermined processing candidate regions from parts of a measurement image that is specified by the measurements of the knee joint of the patient,
creates a predetermined processed image by applying predetermined processing to the processing candidate regions, and subsequently creates the projection image by combining the predetermined processed image with an image other than the processing candidate regions,
receives the measurements of the knee joint of the patient that includes an image of a femur and an image of a tibia of the patient,
sets a first processing candidate region that includes the image of the femur, and a second processing candidate region that includes the image of the tibia, and
creates the processed image by rotating the processing candidate region.
