Implementations may include one or more of the following features. The method may include defining one or more alignment features of the preliminary cutting guide model for the osteotomy procedure. Accessing the bone model further may include: modifying a bone model may include a first modeled bone and a second modeled bone of a joint of the patient such that the first modeled bone is rotated about a longitudinal axis of the first modeled bone from a first position to a second position; defining a first cut surface in the first modeled bone, where the first cut surface is perpendicular to the longitudinal axis of the first modeled bone; defining a first angle for a second cut surface of the second modeled bone, the first angle measured relative to the first cut surface and extends inferiorly away from the first cut surface; defining a second angle for the second cut surface of the second modeled bone, the second angle measured relative to the first cut surface and configured to mitigate the condition; modifying the bone model of the first modeled bone to include the first cut surface and the second modeled bone to include the second cut surface; and where the one or more guide features of a preliminary cutting guide model are configured to enable a surgeon to form the first cut surface and the second cut surface.
