Abstract
Once variation of a system for total knee replacement includes: a first alignment guide defining first set of guides that locate a first set of pins on a first bone of a joint in extension and defining a reference surface relative to the first set pin guides; a second alignment guide constrained relative to the first alignment guide by the reference surface and defining a second set of guides, relative to the first set of guides, that locate a second set of pins on a second bone of the joint; a first cut guide located by the first set of pins and defining a first cut plane for resecting the first bone; and a second cut guide located by the second set of pins and defining a second cut plane, linearly offset from the first cut plane, for resecting the second bone.
