    Abstract: A surgical method for forming a void in bone includes the steps of positioning a support member securely within an intramedullary canal of a bone; attaching a guide member having a longitudinal axis to the support member in a fixed and offset relation to the intramedullary canal; connecting a cutting member having a cutting head to the guide member in a slidable arrangement along the longitudinal axis of the guide member such that the cutting head faces a first bone segment; and cutting the first bone segment along the longitudinal axis of the guide member, thereby forming a first offset bone void.

    Abstract: A cutting guide for performing a bone osteotomy procedure is disclosed. The cutting guide includes a first arm having a first cutting guide surface formed therein, a second arm having a second cutting guide surface formed therein pivotably connected to the first arm and a distractor operatively connected to the first arm. The cutting guide is adapted to be affixed to the bone such that the first cutting guide surface is open to the second cutting guide surface. The first arm and second arm are rotatable with respect to each other such that manipulation of the distractor creates a force between the first arm and the second arm causing rotation of the first arm and second arm relative to each other. A method for using the cutting guide in a bone osteotomy procedure is also disclosed.

    Abstract: Systems and methods for shaping and filling offset bone voids during revision procedures of total knee replacements are disclosed. The systems disclosed herein generally include an intramedullary reamer, an offset driver, a cylindrical reaming tool, an offset reaming guide, and a conical reamer. An alternate embodiment of the system may also generally include an IM reamer, an offset driver, an offset broaching tool, and a second stage broaching tool. Yet another embodiment may generally include an elongate IM reamer, a cone reamer, a reamer guide shaft, a cone trial, a sizing template, a template guide, an offset lobe reamer, and offset lobe reamer retainer. Metaphyseal reconstruction devices and void filling cones can be used to fill the bone voids in conjunction with the systems and methods disclosed herein.

    Abstract: A knee prosthesis includes a femoral component, a tibial component, and a coupling component interconnecting the femoral component and the tibial component. The tibial component includes ball. The femoral component is configured to move relative to the tibial component. The coupling component defines an internal cavity including a first spherical end portion and a second spherical end portion. The internal cavity is dimensioned to receive the ball of the tibial component. The ball is repositioned between the first spherical end portion and the second spherical end portion of the internal cavity upon movement of the femoral component relative to the tibial component.

    Abstract: The present invention relates to systems and methods for preparing the trochlear groove of a patient's femur to receive a prosthesis thereon. In the system, a combination drill-and-alignment guide includes at least a proximal and intermediate section, and preferably also includes a distal section. Guide holes for receiving guide pins therein are located in the proximal and distal sections of the guide. After the guide is positioned using at least one of several visual and/or tactile guide references in the system, the guides pins are placed through the guide holes of the guide and into bone. The guide may then be removed and replaced by cannulated reamers that are rotated and used to resect a predetermined amount of bone around the guide pins. A prosthesis having at least a portion of an outer surface that substantially matches the trochlear groove of the patient in a pre-degenerated state is then implanted on the resected bone.
