Systems for use in total knee arthroplasty include a cutting guide having only a single slot. The single slot is configured to be positioned adjacent an anterior side of the medial compartment of the knee joint with no portion positioned adjacent an anterior side of the lateral compartment of the knee joint. The single slot is adapted to guide an oscillating saw blade across the knee bone from the medial compartment to resect at least a portion of the lateral compartment. The system also includes a total knee arthroplasty implant adapted to be implanted on the resected surface.
