Tibial cut guide

An apparatus for guiding a tibial bone cut to a tibia during a unicompartmental knee replacement surgery, the apparatus comprising:

• a mounting portion configured to couple with an alignment mechanism;
• and
• a cutting portion connected to the mounting portion and offset in one of medial or lateral direction therefrom, wherein the cutting portion defines a first capture configured for receiving and directing a cutting instrument that performs a proximal cut and a second capture configured for receiving and directing the cutting instrument that performs a sagittal cut, wherein the first capture is configured to define a medial-lateral cut length such that the proximal cut is to a single compartment of the tibia, wherein the cutting portion defines an aperture configured to receive a pin that couples the apparatus to the tibia, wherein the aperture communicates with the second capture but spaced one of directly medial or directly lateral from a first end of the first capture, and wherein a portion of the second capture is defined by one or more projections extending proximally from a proximal surface of the cutting portion.
