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.

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.
