Abstract:
1. A method of performing a joint procedure, comprising: securing a base member and an adjustment block to a tibia, the adjustment block having a surgical orientation device coupled therewith, the surgical orientation device having an associated reference system; manipulating the adjustment block in at least one degree of freedom relative to the base member when the base member is in a fixed position and orientation relative to the tibia; manipulating the adjustment block in at least another degree of freedom relative to the base member when the base member is in a fixed position and orientation relative to the tibia; contacting a location on a proximal surface of the tibia on a mechanical axis with a first measuring device; and positioning a second measuring device adjacent to a distal surface to identify a orientation of a plane extending through the tibia which contains the mechanical axis; wherein the associated reference system is determined without the use of optical sensors disposed outside the surgical field.
