1. A method of determining wear of an artificial knee assembly, the method comprising: acquiring a first set of computed tomography data about the artificial knee assembly in vivo; generating a first volumetric artificial knee assembly file based on the first set of computed tomography data; generating a first point cloud data set based on the first volumetric artificial knee assembly file; performing a first dimensional analysis of the artificial knee assembly using the first point cloud data set; generating a second volumetric artificial knee assembly file based on a second set of acquired computed tomography data about the artificial knee assembly before implantation or acquiring the second volumetric artificial knee assembly file from a model; generating a second point cloud data set based on the second volumetric artificial knee assembly file; performing a second dimensional analysis using the second point cloud data set; comparing the first dimensional analysis to the second dimensional analysis; and determining if the first dimensional analysis is different from the second dimensional analysis an amount that exceeds a selected tolerance of the artificial knee assembly.
