Fig. 8A–B.

These are the postresection images superimposed on the images of the preoperative plan for (A) a manually resected specimen and (B) a custom jig-resected specimen. On the manually resected specimen, there is substantial deviation from the preoperative plan (preoperative plan = red lines, which actually outline the femur depicting the preoperative plan—in pure ocean blue and directly visible in the vicinity of the resection). In contrast, on the custom-jig specimen, there is close adherence to the preoperative plan (again represented by the red lines). In the right image, the femur representing the preoperative plan coincides closely with the custom jig-resected specimen and thus is not directly visible.
