System and method of measuring in vivo wear in artificial knee joint

A system for determining wear of an artificial knee assembly, comprising:

• a CT x-ray machine configured to scan an artificial knee assembly in vivo;
• and
• a computer system in communication with the CT x-ray machine, the computer system configured to acquire a first set of computed tomography data about the artificial knee assembly in vivo, generate a first volumetric artificial knee assembly file based on the first set of computed tomography data, generate a first point cloud data set based on the first volumetric artificial knee assembly file;
• and perform a first dimensional analysis of the artificial knee assembly using the first point cloud data set;
• wherein the computer system is further configured to at least one of generate 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 acquire the second volumetric artificial knee assembly file from a model, generate a second point cloud data set based on the second volumetric artificial knee assembly file, perform a second dimensional analysis using the second point cloud data set, compare the first dimensional analysis to the second dimensional analysis, and determine if the first dimensional analysis is different from the second dimensional analysis an amount that exceeds a selected tolerance of the artificial knee assembly.
