title: [Experimental research for position accuracy of caput femoris center in total knee replacement navigation surgery].
abstract: Finding the position of caput femoris center by exact and fast method is a key technique in total knee replacement navigation surgery. A method for finding the position of caput femoris center is described in this paper. The main idea is abstracting this problem to a geometrical model in which the center of a sphere can be easily worked out with a few known spherical points. Experiments show that the method is feasible and the precision satisfies the requirements of navigation surgery.
