41. A method of resecting a tibia, said method comprising:
providing an instrument having an anchoring member and a resection guide;
securing said anchoring member to the tibia;
registering the position of said resection guide in a computer generated guidance system after said step of securing said anchoring member; and
selectively adjusting the position of said resection guide relative to the anchoring member after said step of registering the position of said resection guide.
42. The method of claim 41 wherein said step of selectively adjusting the position of said resection guide comprises securing said resection guide in said selected translational position and independently securing said resection guide in said selected rotational position.
43. The method of claim 41 further comprising the step of directly securing said resection guide to the tibia after said step of selectively adjusting the position of said resection guide.
44. The method of claim 41 wherein said step of selectively adjusting the position of said resection guide comprises positioning said resection guide in selected translational positions along at least two substantially perpendicular translational axes and positioning said resection guide in selected rotational positions about at least two substantially perpendicular rotational axes.
45. The method of claim 41 wherein said step of selectively adjusting the position of said resection guide comprises positioning said resection guide in selected translational positions along three substantially mutually perpendicular translational axes and positioning said resection guide in selected rotational positions about three substantially mutually perpendicular rotational axes.
