1. An orthopedic trial component configured to provisionally replace a portion of a bone of a joint, the orthopedic trial component comprising:
a body portion including:
an outward-facing side defining an articular surface for the joint;
an inward-facing side defining a bone-facing surface configured to abut a resection surface of the bone;
a slide channel formed in the inward-facing side of the body portion, wherein the slide channel extends along a slide axis is defined in part by an opening in the bone-facing surface; and
at least one drill guide extending from the articular surface to the bone-facing surface in a predetermined orientation relative to the body portion;
a fastening mechanism slidably mounted to the body portion for movement along the slide axis, the fastening mechanism including a slider body and a bone-engaging post extending from the slider body, the slider body being at least partially received within the slide channel, the bone-engaging post projecting inwardly beyond the bone-facing surface; and
a selective coupling mechanism for coupling the fastening mechanism to the body portion, the selective coupling mechanism being configured to selectively prevent movement of the fastening mechanism along the slide axis, wherein the selective coupling mechanism is configured to permit movement of the body portion relative to the fastening mechanism when a force along the slide axis exceeds a threshold force value, and to prevent movement of the body portion relative to the fastening mechanism when the force along the slide axis does not exceed the threshold force value;
wherein the selective coupling mechanism is configured to exert frictional forces between the slide channel and the fastening mechanism to resist but not prevent relative movement of the body portion and the fastening mechanism.
