Abstract:
1. A system for locating a femoral cutting guide on a distal end of a left or right femur that establishes at least a first reference plane to perform a distal femoral planar cut, the system comprising: a mounting rod insertable into the distal end of the femur, the mounting rod having a cross-section with an anti-rotational shape; a bushing having an aperture corresponding to the shape of the cross-section of the mounting rod for receiving the mounting rod; an index member receiving the mounting rod at an offset such that the index member can be positioned to abut the distal end of the right femur in a first configuration and the distal end of the left femur in a second configuration; a bridge member couplable to the index member selectively in the first and second configurations; a cutting guide member that couples to said bridge member, said cutting guide member having a first channel that establishes the first reference plane; and one or more magnets that releasably couple said cutting guide member to said bridge member, wherein the magnets are operable to generate a sliding resistance between the bridge member and the cutting guide member that is generally overcome to position the cutting guide member relative to the femur, wherein the bridge member has an elongated post removably receivable into an aperture defined in a wall of the index member, the bridge member having a channel having a wall received into the first channel of the cutting guide.
