A method for assessing the orthopaedic performance of a joint of a patient can comprise implanting at least a first and second RF wirelessly detectable markers in first and second bones associated with a site and determining and storing their positions before a surgical procedure is performed. The procedure can be carried out on the site and the positions of the first and second markers can be detected and stored after the procedure has been completed. The detected positions can be used to generate a representation of the orthopaedic performance of the joint after the procedure.

Orthpaedic monitoring system, methods and apparatus

A method for position tracking includes using first and second field generators located at respective different first and second locations to generate respective first and second magnetic fields in a vicinity of first and second objects. The first and second fields are measured using first and second position sensors respectively associated with the first and second objects. First and second potential relative coordinates of the first object relative to the second object are calculated responsively to the first and second magnetic field. The potential relative coordinates are processed in order to determine a correct relative coordinate of the first object relative to the second object.
