System and technique for accessing extra articular lesions or abnormalities or intra osseous lesions or bone marrow lesions

A system for accessing extra articular lesions or abnormalities or intra osseous lesions or abnormalities or bone marrow lesions, comprising an intra articular localizing pinning member to determine a location of the lesion or abnormality;

• an adjustable guide component, the adjustable guide component having a first arm and a movable second arm, the first arm having a first end and a second end, the first end of the first arm attachable to an exposed portion of the intra articular localizing pinning member at a predetermined position on a shank of the localizing pinning member and the second arm being coupled to a coupling at the second end of the first arm, the coupling configured to move along a straight portion of a second arm, the straight portion of the second arm extends to a curved arcuate portion of the second arm, the curved arcuate portion holds a movable guide component for locating an entry access;
• and wherein the utilization of the localizing pinning member includes positioning an end of the localizing pinning member onto cartilage or subchondral bone without entering the bony lesion or abnormality to define a virtual pathway extending from the end of the localized pinning member through the lesion or abnormality prior to creating a first entry access, holding the end of the localizing pinning member against the cartilage or subchondral bone positioned along the virtual pathway, wherein manipulating the adjustable guide component about the localizing pinning member establishes a first entry access point for the creation of the first entry access based on the relevant anatomy at a location where the movable guide component is set on the curved portion of the second arm so a track extending from the first entry access point is adjustably aligned to intersect the virtual pathway at the desired target location or adjusted therefrom by a fixed distance on the virtual pathway by moving the movable second arm relative to the first arm.
