Abstract
Surgical instruments for use in mapping tissue defects include telescoping rulers and tubes. One of the instruments has a pointed anchoring tip for piercing tissue near the site of the defect. Another instrument has a hook for catching an anatomical landmark. Measuring portions of the rulers of both instruments include distance indicia so that a coordinate system can be established for mapping the location of the defect or of an implant at the defect site. The coordinate system can be re-established at a later time using the same fixation point for the anchoring tip and the same landmark for the hook to evaluate the clinical effects of the treatment selected. The method of using the instrument set is also described.
