The site marking will be performed by the surgeon in a standardized manner using the standard marker supplied at the hospital (Sharpie Fine Point Permanent Marker, Sanford Corporation, Oak Brook, IL, USA). All markings will be made in the pre-operative holding area per usual routine. The site marking will be made next to the site of the incision on the anterior thigh. The site marking will include the surgeon's three initials as per usual routine. Underneath the surgeon's initials, three random initials will be placed with a horizontal line drawn underneath. Twenty random three-letter combinations will be pre-generated using MS Excel® (Microsoft Office 2003, Microsoft Corporation, Seattle WA).
