1. A bone-cutting guide, comprising:
at least one rail configured to be positioned proximate a bone;
a cutting block disposed on the rail, the cutting block comprising a cutting slot configured to receive a cutting blade therethrough; and
a tracking unit configured to provide data associated with a location and an orientation of the cutting slot;
wherein the cutting block is repositionable relative to the at least one rail between a plurality of cutting block positions;
wherein, in each of the plurality of cutting block positions, the cutting slot defines a respective cutting plane for the cutting blade to cut the bone;
wherein the cutting slot is configurable between an unblocked configuration and a blocked configuration;
wherein, in the unblocked configuration, the cutting slot is capable of receiving the cutting blade therethrough;
wherein, in the blocked configuration, the cutting blade is prevented from passing through the cutting slot;
wherein the cutting slot is configured to automatically change between the unblocked configuration and the blocked configuration based at least in part upon the location of the cutting slot and the orientation of the cutting slot relative to at least one preplanned cutting plane; and
wherein the cutting slot remains blocked until such time that the location and orientation of the cutting slot match the at least one preplanned cutting plane.
