The present disclosure provides a cut guide for use in preparation of the distal femur to form the anterior, anterior chamfer, distal, posterior chamfer and posterior facets as well as the intercondylar box cuts utilized to prepare a femoral intercondylar box. To allow for the use of a single cutting guide to make all of these femoral osteotomies, the present disclosure implements an orthopedic guide assembly including a primary guide body with a secondary guide body rotatably connected to the primary guide body. With this configuration, the secondary guide body can be rotated into an operable position to guide a femoral osteotomy and may also be rotated into an inoperable position in which it is moved from a configuration (i.e., the operable position) in which it acts as a barrier to movement of an osteotome across a guide surface of the primary guide body.
