1. A technique for accessing extra articular lesions or abnormalities or intra osseous lesions or abnormalities or bone marrow lesions or all, comprising the steps of:

  • pinning an intra articular localizing pinning member by inserting the localizing pinning member through cartilage and / or subchondral bone into a lesion or abnormality to locate and stabilize by intra articular pinning the lesion or the abnormality with the localized pinning member to create a first entry access, wherein the localizing pinning member is configured to be left in the first entry access and includes a graduated or calibrated depth scale on a shank of the localizing pinning member to indicate the distance to a tip or end of the localizing pinning member;

    attaching a guide component onto the pinning member over an exposed portion of the localizing pinning member when pinned in the lesion or the abnormality, the guide component having a first arm with an end with a shank tightening nut for attachment to the localizing pinning member and a second arcuate arm;

    positioning the guide component at a predetermined position on the shank of the localizing pinning member while maintaining the guide component movable about the localizing pinning member;

    manipulating the guide component to achieve a desired path and rotational position along or about the localizing pinning member by rotating the guide component about the localized pinning member to establish a desired location for the creation of a second entry access based on relevant anatomy to form a blind angled osteal tunnel or channel and tightening the shank tightening nut to secure the guide component to the localizing pinning member, wherein the guide component includes a movable guide which is continuously adjustable along a circumferential arc on the guide component anywhere along a portion of the second arcuate arm of the guide component to be set or fixed at the desired second entry access point;

    positioning the movable guide along the second arcuate arm at the desired second access point; and

    utilizing the fixed or set movable guide of the guide component for passing a drill, a pin or a punch through the guide component to the second entry access to a desired depth within or in the proximity of the lesion or the abnormality.
