Abstract: Methods and apparatus provide for modifying a patient's femur to receive a patellofemoral prosthesis, including: a distal punch, an anterior punch and a trochlear punch which are used in well defined orientations to remove material from the femur to accommodate complex geometries of a patellofemoral prosthesis; and optionally a guide operating to engage a distal end of the femur, the guide including a distal slot, an anterior slot and a transverse slot, which ensure that the punches achieve the desired orientations.

Abstract: Methods and apparatus provide for modifying an intercondylar notch of a patient's femur, including cutting bone from the intercondylar notch using a hole saw having a hollow cylinder and a circular cutting edge, where the hollow cylinder of the hole saw defines a central longitudinal axis which is oriented with reference to the patient's femur such that the circular cutting edge of the hole saw removes a portion of material from the intercondylar notch of the patient's femur.

Abstract: The present invention provides for an apparatus for cutting a tibia, a stylus, an apparatus for cutting a femur, an apparatus for aligning a femoral cutting guide, and an ankle clamp in support of a unicondylar knee surgery. The present invention further provides for a method of preparing a femoral condyle of a femur for the implantation of a unicondylar femoral knee implant. The apparatus for cutting a tibia includes a unicondylar tibial resection guide that is adjustably connectable to a unicondylar tibial alignment guide and configured to operate concurrently with the tibial alignment guide. The apparatus for cutting a femur includes a spacer block and a cutting guide configured to operate concurrently with the spacer block.

Abstract: A unicondylar knee implant system according to one embodiment includes a unicondylar femoral knee component having a single sagittal radius, a tibial bearing component, and a tibial tray component having a self-locking keel. The unicondylar knee implant system also provides for a locking mechanism for securing the tibial bearing component onto the tibial tray component. The unicondylar knee system allows for a simplified surgical technique, complete interchangeability between sizes, and a more MIS compatible implant system.

Abstract: A cutting block includes a body having at least three sections spaced in the anterior-posterior direction. Each section has a proximally facing surface for being placed adjacent to the distally facing surface of the femur. The block includes a distally facing surface with a rib connecting the at least three sections. The rib extends outwardly from the distally facing surface of each of the sections of the cutting block. The rib spaces the sections to form a guide slot between adjacent sections for receiving a saw blade. The rib has a proximally facing surface spaced distally of the distal surface of the cutting block adjacent the slots.
