Claim:
A system for positioning a cutting guide for preparation of a bone of a patient during total knee arthroplasty, comprising: an adjustor for adjusting said cutting guide at the bone; structures operatively associated with the adjustor for adjusting the position of the cutting guide in at least one degree of rotational freedom and at least one degree of translational freedom, at least one of the structures operatively associated with the adjustor configured to convert rotational motion of the at least one structure to translational motion of the cutting guide such that rotation of the at least one structure in a first rotational direction drives the cutting guide in a first translational direction; structures for stabilizing the adjustor at the bone; and structures for engaging the cutting guide; wherein the adjustor further comprises a module for attaching the adjustor to the bone; wherein the module for attaching the adjustor to the bone is for attaching the adjustor to an anchor post or to an intramedullary rod; and wherein the module for attaching the adjustor to the bone is adjustably connected to ball-and-socket structures by a translationally adjustable connection.
