It was found that, the states of stress on the hip joint immediately after the operation and 6 weeks after of the operation, were almost the same as for a normal joint. This finding corresponds to the treatment policy of the medical field for the results of a dynamic examination, and it has therefore been understood that this is a steady dynamically operation method.
