1. An assembly of a tool and of a patient-specific rotational guide for guiding a positioning of the tool on a planar resected surface of a bone in an articular joint repair procedure, the assembly comprising:

  • the tool having a planned position relative to the planar resected surface of the bone and having a plate portion with a flat surface adapted to be placed against the planar resected surface such that the plate portion with the flat surface moves along the planar resected surface;

    the rotational guide including a body, a tool attachment member attached to the tool, and a bone contacting member having a bone contacting surface adapted to contact a bone and shaped using patient-specific modeling to conform to a shape of a bone surface adjacent to the planar resected surface, a patient-specific arrangement between the rotational guide, the tool and the bone corresponding to a pre-operative planning defined by a mating contact between said bone surface and the bone contacting surface when the tool is positioned in the planned position on the planar resected surface.
