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.

Abstract
Systems and methods for joint replacement are provided. The systems and methods include a surgical orientation device and at least one orthopedic fixture. The surgical orientation device and orthopedic fixtures can be used to locate the orientation of an axis in the body, to adjust an orientation of a cutting plane or planes along a bony surface, to distract a joint, or to otherwise assist in an orthopedic procedure or procedures.

10. A method of performing a joint procedure, comprising:
-
securing a base and an adjustment block adjacent to a proximal portion of a knee bone, the adjustment block coupled to the base by at least one hinge and to a surgical orientation device having an associated reference system that is determined without the use of optical sensors disposed outside the surgical field; adjusting the adjustment block in two transverse degrees of freedom when the base is secured adjacent to the knee bone to adjust a medial-lateral angle and an anterior-posterior angle of the adjustment block; coupling a landmark acquisition device to the adjustment block; and contacting a distal portion of the knee bone with the landmark acquisition device. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A method of performing a joint procedure, comprising:
-
securing a base and an adjustment block adjacent to a proximal portion of a knee bone, the adjustment block having a surgical orientation device coupled thereto; determining a reference system of the surgical orientation device by generating inertial or optical signals from within the surgical field; adjusting a medial-lateral angle and an anterior-posterior angle of the adjustment block when the base is secured adjacent to the knee bone; and contacting a distal portion of the knee bone with a landmark acquisition device that is coupled with the adjustment block. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27)
