Abstract

In this paper, mathematical tools, like Monte Carlo simulations and direct propagation methods based on the GUM, are experienced to calculate the uncertainty of a datum reference in orthopedic surgery. In the last approach, the Jacobian matrices of the measurement process are determined either by analytical calculus or through numerical computations. The methods are applied to the determination of reference frames in total knee arthroplasty. The different approaches are employed to calculate the uncertainties and the results are compared.
