A system for accessing lesions or abnormalities using intra articular localization has an arm and a guide component. The arm with a localizing pin at a first end defines a virtual pathway. The guide component has a straight guide portion and a curved guide or arcuate portion. The curved guide or arcuate portion has a plurality of angularly spaced guide openings for passing a pin or drill or pin or punch along a selected path to form an entry access. The straight guide portion is for holding or coupling the arm at or in proximity to a second end of the arm. The selected path extends toward the virtual pathway to form the entry access using intra articular localization.
