An osteotomy guide is provided for cutting a bone, such as the medial distal tibia, to facilitate an ankle replacement. The osteotomy guide includes a positioning device having a number of fixation points, a first guide member structured to align with a first portion of the bone, in order to perform a first procedure, thereon, and a second guide member structured to align with a second portion of the bone, in order to perform a second procedure thereon. The fixation points engage the bone and maintain alignment of the first guide member with respect to the first portion during the first procedure, and maintain alignment of the second guide member with respect to the second portion during the second procedure, in order that the first procedure and the second procedure are substantially reproducible.
