A patient is having surgery on his left elbow. Which elbow should be marked by the surgeon as the surgeon faces the patient?

The patient’s left and right are defined from the patient’s own perspective. As the surgeon faces the patient, the patient’s left elbow appears on the surgeon’s right, but it is still the patient’s left elbow that must be marked. Therefore, the surgeon should mark according to the patient’s perspective.
