Abstract

A computer-implemented method for determining implant positions of two implant components relative to two bones that form a joint is disclosed. The method includes acquiring a set of target poses to be achieved between the two bones, assessing one or more proposed implant arrangements using the set of target poses, and selecting an implant arrangement from the proposed implant arrangements based on the assessment. Assessing an implant arrangement includes determining a real pose between the two bones for each target pose, calculating a pose deviation value for each target pose based on the target pose and the corresponding real pose, and calculating an overall pose deviation value from the individual pose deviation values. The implant arrangement may be selected based on the overall pose deviation values for the proposed implant arrangements.
