A coordinate mapping system is provided for locating a defect in a bone. The system comprises a positioning instrument for controlled delivery of a device to a target site, the instrument comprising a main body and a rail extending from the main body, the rail including a series of indicia corresponding to predefined grid lines, and a template configured to overlay an image of a bone having a defect at the target site, the template including a predefined grid for determining a set of coordinates to locate the target site using the positioning instrument. A method of accessing a target site near a defect in a bone using the radial coordinate mapping system is also provided.
