The method of claim 1, further including controlling movement of the first member relative to the second member of the orthopedic brace external to the subject'"'"'s body by one or more force-applying elements, wherein the one or more force-applying elements in response to the one or more controllers permit unrestrained motion of the internal orthopedic joint prosthesis under a first set of the one or more alignment orientations and permit restrained motion of the internal orthopedic joint prosthesis under a second set of the one or more alignment orientations.

3. The method of claim 2, further including controlling application of force to the internal orthopedic joint prosthesis by the one or more force-applying elements by the one or more controllers.

4. The method of claim 2, wherein the one or more force-applying elements are configured to exert force on the first component relative to the second component of the internal orthopedic joint prosthesis.

5. The method of claim 4, wherein the one or more force-applying elements are configured to exert linear force or rotational force on the internal orthopedic joint prosthesis.

6. The method of claim 1, further including restraining motion of the internal orthopedic joint prosthesis by the orthopedic brace external to the subject'"'"'s body under a first set of the one or more alignment orientations, and permitting unrestrained motion of the internal orthopedic joint prosthesis by the orthopedic brace external to the subject'"'"'s body under a second set of the one or more alignment orientations.

7. The method of claim 6, wherein the first set of the one or more alignment orientations includes alignment of the internal orthopedic joint prosthesis based on information related to the subject'"'"'s joint orientation prior to prosthesis implantation, or 3-D modeling of the subject'"'"'s joint.

8. The method of claim 6, wherein the second set of the one or more alignment orientations includes a separation of the first component relative to the second component of the internal orthopedic joint prosthesis.

9. The method of claim 6, further including restraining motion to stop motion of the internal orthopedic joint prosthesis.

10. The method of claim 6, further including restraining motion from the second set of the one or more alignment orientations towards the first set of the one or more alignment orientations.

11. The method of claim 6, further including restraining motion to reduce one or more differences between the second set of the one or more alignment orientations and the first set of the one or more alignment orientations.

12. The method of claim 1, further including detecting the one or more alignment orientations of the internal orthopedic joint prosthesis with one or more second sensors configured to be remote from the internal orthopedic joint prosthesis.

13. The method of claim 1, further including measuring one or more properties of tissue surrounding the internal orthopedic joint prosthesis with one or more tissue sensors.

14. The method of claim 1, further including measuring strain on one or more of ligament, muscle, or bone of the mammalian subject surrounding the internal orthopedic joint prosthesis with one or more strain sensors.

15. The method of claim 12, wherein detecting one or more alignment orientations include detecting one or more of pressure, angle, motion, strain, flexion, extension, position, force, speed, or acceleration of the internal orthopedic joint prosthesis with the one or more second sensors.

16. The method of claim 1, further including detecting one or more of chemical change or biological change in the mammalian subject with one or more biological or chemical sensors.
